Hurricane Preparedness Week: Put Your Emergency Plan to Work

Satellite imagery shows three positions of hurricane Andrew before, during, and after it hit Florida.

The Path of Hurricane Andrew

Surviving a hurricane requires planning before a storm threatens. The Atlantic Hurricane Season begins June 1, 2014, and the Eastern Pacific Season has already begun and has already seen the first tropical cyclone of the season.

It is important to understand the tropical storm and hurricane hazards and how they can affect your home. If you live on or near the coast where hurricanes are possible, then you should already have a plan in place in the event a hurricane or tropical storm threatens. When forecasters determine a storm threatens, the time has come to put that plan into action.

Put together an emergency disaster kit and stock it with supplies for at least one week. Plan your escape route ahead of time and if you are forced by the weather or ordered by authorities to evacuate, exit along the planned route and go to the safe haven you have chosen.

Storm Watches

Chart showing wind speed tropical depressions, storms, and hurricanes.

Saffir Simpson Scale

Watches are issued 48 hours ahead of the arrival of tropical-storm-force winds. Tropical storms have sustained winds from 38 to 73 mph. Hurricane winds start at 74 mph.

When a watch is issued for your area, the time has come to activate your plan immediately. Check your emergency disaster kit, identify missing items, and replenish them if necessary. Of utmost importance are medications, food, and water for at least three days, and a week is better.

Fill your car with fuel so you can evacuate if necessary without stopping to wait in long gas station lines. Check supplies of fuel for portable generators and top off supplies if necessary. Ensure that standby generators have an adequate supply of liquid propane if they run off the home’s tank. Perform any necessary maintenance and restock maintenance supplies like oil, filters, and plugs.

If you have a boat moored at a marina, you may have to move it to a safer location.

Storm Warnings

Hurricane Get Ready

Hurricane Get Ready

A hurricane or tropical storm warning means that tropical-storm-force winds will occur within 36 hours or sooner. You should already have put your emergency plan into action.

Listen to local news for updates and notifications on evacuation orders. Stay informed by listening to your NOAA radio and by visiting the National Hurricane Center website.

If evacuation becomes necessary:

  • Close storm shutters or board up windows and doors.
  • Turn off the gas and water.
  • Take your emergency disaster supply kit with you, along with clothing, medications, and personal items. Pack your car and leave along the evacuation route you have planned. Go to the planned location where you will wait out the storm in safety. Do not return until authorities have declared an area safe.

If you stay home:

  • Do not venture outdoors during the storm. Stay in the room previously chosen as your shelter until the storm ends.
  • Don’t be fooled into believing the storm is over before authorities give the all clear. The eye of the storm passes quickly and the high winds return suddenly.
  • Stay alert and informed. Listen to your weather radio for information. Remember that cell phones often work when regular land lines do not, but cell networks may become overwhelmed in the aftermath.
  • Stay close to your shelter after the storm has ended. Be aware of post-storm hazards including flooding and downed power lines. Although it is tempting to move around and survey the damage, remember that putting your own life in danger may also put a rescuers life at risk as well.
  • Monitor your standby generator and be sure to check the oil on a regular basis according the manufacturer’s instructions. Standby generators can operate a long without refueling, but they need regular maintenance when run for extended periods.
  • Conserve fuel if you’re using a portable generator. Lowering the electrical load will reduce fuel use, and running the generator only when necessary is a good idea. Keep refrigerators and freezers closed except when the generator is running, and only open them when necessary. A freezer can easily keep food frozen for twelve hours or more if the door is not opened.

Hurricane Preparedness Week: Get a Plan and be Ready to Act

National Hurricane Preparedness Week 2014 Banner for May 25th to May 31st.

National Hurricane Preparedness Week

The Atlantic Hurricane Season begins on June 1 and runs through the end of November. According to the Federal Emergency Management Agency, if you live on the coast or inland from the coast you should take steps to formulate a plan now before a storm threatens your community. Be informed about the hazards associated with hurricanes and tropical storm and know what you can do to protect your family and home before, during, and after a weather-related disaster.

Know the Hazards

Direct hazards are components of a hurricane that threaten life and property and include extreme winds, storm surge, and inland flooding. Indirect hazards are caused by the hurricane, but are not part of it. They include tornadoes spawned by the hurricane, rip currents that pose a danger to swimmers and beach goers, waves that are higher and travel further up the shore than normal, and power outages caused by damage to the distribution system.

Most people are familiar with the direct hazards, but rip currents can occur long before the hurricane threatens land, even when it is hundreds of miles offshore. Some hurricanes spawn tornadoes by the dozens and by the time storm dissipates, they may total in the hundreds.

Tropical storms, though less intense than hurricanes, can inundate inland areas with incredible amounts of rainfall that overwhelms waterways and flood control systems to cause widespread inland flooding. Weaker storms have a history of producing the most rain and causing some of the worst inland flooding.

Get a Plan

Take the first step in forming a plan and visit, a website by FEMA that provides information on preparing for disasters like hurricanes and tropical storms. You will find information on putting together a disaster kit, planning for evacuation, and how to live safely in the days and weeks following a disaster.

Find out if you live in an evacuation zone. Learn the evacuation routes and plan to leave as soon as an evacuation notice is issued. Part of your evacuation plan should include knowing where you will go when you evacuate. Your plan might include sheltering at relatives, a motel or hotel, or in some cases you may need to stay at an emergency facility.

Emergency Disaster Kit

Put together an emergency disaster kit. Disaster kits should be portable so you can take them with you in the event you are required to evacuate.


  • Three days of non-perishable food and three gallons of water for each person.
  • Battery-powered or crank-powered NOAA weather radio with extra batteries.
  • Flashlight with extra batteries.
  • First aid kit.
  • Dust mask for each person.
  • Plastic sheeting and duct tape to create temporary shelter if required.
  • Moist towelettes, toilet paper, garbage bags and plastic ties for human waste disposal.
  • Tools for turning off utilities—channel-lock pliers or wrenches.
  • Hand-held can opener.
  • Local map.
  • Cell phone, charger, and inverter.

If your local officials recommend evacuating, don’t wait. It is better to leave and return later than to be trapped in a situation that grows worse and makes leaving impossible.

Before you leave, turn off your natural gas at the meter (requires a wrench or large pliers) or your propane at the tank. Shut off the water (some homes require a wrench or large pliers to turn the valve.) Turn off the electricity at the main disconnect. Lock your doors and windows and board them up if possible.

Plan to Stay

If you are not in an evacuation zone, you still must act to ensure your safety. Areas that flood are highly susceptible to flash flooding during a hurricane or tropical storm, even if you live inland from the coast.

  • Store at least seven gallons of drinking water for each person—a weeks supply.
  • Keep seven days of non-perishable food for each person. Include a can opener.
  • Flashlights, cell phones, NOAA weather radio and extra batteries.
  • Portable generator for emergency power and seven days worth of fuel. Include two maintenance kits with oil, filters, and spark plugs.
  • Have a standby generator installed. They provide emergency power automatically, run on natural gas or propane, and reduce your reliance on liquid fuels.
  • Build the FEMA emergency disaster kit, keep it handy, and take it with you if conditions make it impossible to stay.

If you’re in the direct path of a hurricane and hurricane warnings have been issued, don’t wait. Take your emergency kit, your clothing, medicine, and personal items, and leave. There is no better plan of action than to get out of a hurricane’s path.

Hurricane Preparedness Week: Forecasting Tropical Cyclones

The National Hurricane Center (NHC) is a division of the National Weather Service (NWS), an agency within the National Oceanic and Atmospheric Administration (NOAA). The NHC is responsible for forecasting and tracking tropical cyclones and their associated hazards in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and Eastern Pacific Ocean.

National Hurricane Preparedness Week 2014 Banner for May 25th to May 31st.

National Hurricane Preparedness Week

Tropical cyclones are the largest cyclonic weather event on the Earth and a large storm can span more than 1000 miles in diameter. Storm classifications include depressions, storms, hurricanes, and major hurricanes. The most intense tropical cyclone on record was Hurricane Allen in 1980. It was the first and strongest hurricane of the season and formed on July 31. Allen had sustained winds of more than 190 MPH, the highest of any hurricane on record.

Collecting Data

The NHC collects data to determine when and where tropical cyclones are likely to form. They forecast storm intensity and direction, and determine a likely path the storm will follow from a number of hypothetical models that use current and historical data to formulate a storm track.

Data is collected from satellites, ships, buoys, air craft, radio soundings, radar, and automated surface observation stations from all over the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico and includes factors like pressure systems, wind speeds, ocean temperatures, humidity, and much more. The formation of a tropical cyclone is dependent on all these factors, and once formed, how they also affect how the storm will grow and how intense it will become.

The information gathered is added to computer models which use a combination of current and historical data to determine what chance a weather system has of forming a tropical cyclone.

Categorizing a Storm

Chart showing wind speed tropical depressions, storms, and hurricanes.

Saffir Simpson Scale

Tropical cyclones get their energy from warm ocean water and the warm air over the ocean. Storms over the warm water intensify and begin to rotate. As organization (the horizontal rotation and the circulation of air into, up and out from the system center) increases, the storm becomes a tropical depression and is given a number. Tropical depressions have sustained winds less than or equal to 38 mph.

Increased organization will allow the sustained wind speed to exceed 38 mph. The storm will have circulation that is apparent in the shape of its cloud structure. Satellite imagery clearly shows this rotation. Once sustained winds reach 39 mph, the classification changes to a tropical storm and the system is assigned the next name in the list for that year.

If organization continues, the storm may intensify into a hurricane with sustained winds of 74 mph. Major hurricanes have sustained winds greater than 110 mph.

Forecast Cycle

The NHC updates forecasts on tropical cyclones every six hours. Data collection from all the sources is synchronized at various times to increase efficiency, which reduces the amount of time needed to update the forecast. Forecast times are at 00:00, 06:00, 12:00, and 1800 UTC (Coordinated Universal Time). It takes time to put together a forecast and coordinating data collection at specific times allows forecasters to issue advisories on a regular schedule.

Location of the storm, size of the storm, and strength of the storm are considered when issuing advisories. During the forecast cycle, if observations warrant immediate updates, the NHC will issue special advisories between usual forecast times.

The forecast cycle increases accuracy and allows forecasters to fine tune the forecast as a storm approaches land. This increases public confidence in the forecast and in the process saves lives.

Public Response

Timely and accurate forecasts with warnings and watches allow government officials time to respond and evacuate areas in the direct path of a storm. They also give residents advance warning and allow them time to respond by boarding up homes, checking supplies of food, water, and fuel for electric generators.

With 24 to 36 hours of notice, people have time to make last minute preparations or evacuate in a timely manner ahead of clogged roadways. It is important to have a plan and to be able provide for yourself in the hours and days after a hurricane makes landfall and devastates cities, towns, and rural areas.

Hurricane Preparedness Week: Torrential Rain and Inland Flooding

Tropical cyclones produce copious amounts of rain. The energy released when rain drops condense are what provide the storm with it’s high winds. Conversely to wind speed, it is the less intense tropical cyclones that produce the most rain.

It is not uncommon for a major hurricane to dump 12 inches of rain across a wide area, but a weaker storm can easily produce local amounts that exceed two feet or more. Torrential rains cause inland flooding when waterways and flood control systems are overwhelmed by the influx of rain.

Don’t be caught unaware. Visit the National Hurricane Center website for more information.

Extreme Rain

One-quarter of all deaths associated with hurricanes are caused by inland flooding. One characteristic of tropical cyclones is their slow movement, and weaker storms can stall or move even slower than strong storms. This allows more rain to fall in localized areas and the result is catastrophic flooding.

In 2001, Tropical Storm Allison formed out of a tropical wave over the Gulf of Mexico in early June. It struck the Texas coast and moved inland, eventually reaching Luftin, Texas where it met a high pressure system and stalled before it changed direction and moved back over the Gulf of Mexico.

While over Texas, Allison dropped more than 40 inches of rain. Houston had 70,000 flooded homes and more than 30,000 people were left homeless. Forty-one people died as result of the storm. Damage estimates in Texas topped 5.5 billion dollars.

But Allison wasn’t finished. It’s remnants stalled again over the Gulf of Mexico. It then moved to the northeast and strengthened. It made landfall a second time at Morgan City, Louisiana with winds of 45 MPH.

Twenty one tornadoes added to the destruction.

Inland Flooding

Tropical Storm Allison is a good example of why coastal and inland residents should not rely on the Saffir-Simpson Scale as a measure of a tropical cyclone’s strength. Allison was a relatively weak tropical storm that formed very early in the season, but it had a long history and a track that took it across a wide swath of the Gulf and Mid Atlantic States.

Photographer Jim Occi captured these photos of gas lines in Cranford on Thursday following Hurricane Sandy.

More than 230 flash flood warnings were issued by the National Weather Service while the storm was over land. Even after Allison crossed the southern states and moved over the Atlantic Ocean, it continued to dump rain over a wide land area all the way to Long Island and Massachusetts, and inland flooding followed the rain, resulting in road closures and evacuations.

The Red Cross opened nearly fifty shelters and served more than 300,000 meals during the disaster. Because of the extreme rainfall and the extent of the inland flooding, Tropical Storm Allison was the deadliest and most costly tropical storm in the history of the United States, even though it was a relatively weak tropical cyclone.

Inland Flooding Preparation

NOAA logo for the all hazards weather radio systemWeather radios are an essential piece of equipment for every household in the United States. Weather alerts issued by the NOAA and the National Weather Service are invaluable information tools, and knowledge can save your live and the lives of your family.

Flash flood warnings saved hundreds of lives in Texas during Tropical Storm Allison. The average advance notice before a flood was just 39 minutes, and a weather radio can give you the most up to date information available ahead of local news stations who must receive the information, interpret it, and then rebroadcast it.

Purchase flood insurance. Most homeowner insurance policies explicitly deny coverage for damage caused by flooding. Flood insurance is government guaranteed insurance program that mitigates damage and loss of property from a flood.

Inland flooding also contaminates water supplies. Each person needs a minimum of one gallon of drinking water per day, and another gallon for personal hygiene. Stock potable water in containers, and store it above rising water levels.

Isolated by flood waters, a backup generator for emergency home use can keep your food cold, your sump pump running, and even run your air conditioner. Standby generators work with an automatic transfer switch to isolate your home from the electrical grid and local distribution system while supplying you with the power you need to keep your family and property safe. They are automatic systems that operate on a home’s natural gas or propane supply and can run for extended periods without the need for refueling.

Hurricane Preparedness Week: Extreme Wind Hazards

Palm trees bent nearly horiztonal by hurricane-force winds.

Palm Trees Bent by Hurricane-Force Winds

Mention hurricane and the first thing people think of is the extreme wind that impacts structures and landscapes when the storm comes ashore. Television images depict reporters leaning into the wind and horizontal rain.

The winds associated with a tropical cyclone can shred structures, uproot or snap trees, and turn just about anything into a deadly missile. Coast dwellers typically board up their windows and doors when a hurricane threatens in order to keep the glass intact and keep the rain out.

The high winds, the debris they carry, and the trees they topple are all closely related to the widespread power outages as distribution systems are damaged and in some cases, destroyed.

Storm Intensity

Chart showing wind speed tropical depressions, storms, and hurricanes.

Saffir Simpson Scale

Tropical cyclones are graded by intensity using the Saffir-Simpson scale which has three classifications: Tropical Depression, Tropical Storm, and Hurricane.

All three storms are cyclones, but the hurricane is the most organized and the strongest of the three. Hurricanes are categorized on a scale of 1 to 5, with five being the most intense. The Saffir-Simpson Scale excludes information about locations, barometric pressure, storm surge and inland flooding, all which effect the amount of damage the storm is capable of.


Less known are the tornadoes that a hurricane can spawn after it makes landfall. As the tropical cyclone begins to decay, the low pressure and difference in wind speed between the upper and lower levels in the atmosphere make conditions ripe for tornado formation. This also makes it likely that tornadoes may form far inland from the coast, and before the eye reaches land. Most tropical-cyclone related tornadoes form 50 to 200 miles from the eye, but some storms have had tornadoes within the eye or the eye wall.

Tropical-cyclone tornadoes may form out of small storm cells that appear harmless on radar, especially if they are far away from the radar equipment.

Nearly all tropical cyclones that make landfall cause at least one tornado to form, but the number is often much higher. Hurricane Ivan spawned at least 117 tornadoes which by themselves caused eight deaths and 17 injuries. Tornadoes formed when a tropical cyclone comes ashore are typically weaker and shorter lived, but they are still a force to be reckoned with and planned for and inland residents should take precautionary measures to keep themselves safe.

Prepare for High Winds

If you live near the coast, invest in a supply of plywood for boarding up your house. It’s a good idea to cut and label plywood for each window and door in the home. Have sufficient fasteners on hand and a battery powered drill to drive screws with. Screws hold better than nails and should be long enough to reach well into the home’s structural frame.

Visit for information on preparing an emergency disaster kit and formulating a plan to help your family safely survive a tropical-cyclone-related disaster.

Choose a shelter room away from exterior walls, preferably at ground level and without windows. Ideally, the room should not be open to other rooms and have wooden doors. The shelter room will help protect you and your family from flying debris and shattered window glass.

Stay indoors, in your shelter room, and don’t go outside. Stay away from windows.

Power Outages

Generac model# 5875Tropical storm and hurricane force winds can damage the utility lines and equipment directly, while flying debris slices through transmission and distribution lines and wrecks transformers and substations.

Power outages during and after a hurricane or tropical storm are very common and usually widespread. They often affect millions of utility customers and many residents will wait a full week after the storm for the utility to restore power. Some will wait much longer.

Emergency power supplied by a standby generator will turn on automatically and continue to run for an extended period of time without frequent refueling. Standby systems use municipal natural gas supplies or may run on propane supplied by the home’s tank. If a standby system is impractical, portable generators can operate appliances via extension cords. A manual transfer switch and inlet box allows a portable generator to power furnaces, air conditioners, and other permanently wired appliances.

Hurricane Preparedness Week: Storm Surge and Coastal Flooding

National Hurricane Preparedness Week 2014 Banner for May 25th to May 31st.

National Hurricane Preparedness Week

News television networks often talk about storm surge and how it can overwhelm dikes and levees, cause damage to shorelines, and inundate coastal areas with fast rising water. When storm surge combines with a high tide, the effect is even more pronounced.

Coastal regions experience the greatest loss of life and property from the storm urge. High winds drive waves that batter shorelines and structures while the water level rises dramatically, sometimes more than 20 feet. The higher than normal water level allows the waves to reach further onto the shore than waves of a similar height.

Storm Surge

Depiction of wind and pressure storm surges

Storm Surge

Atmospheric pressure pushes down on the ocean surface. If pressure were equal everywhere, it would have no effect on water level. However, the center of a hurricane is an area of very low pressure which differs substantially from areas outside the storm. As the atmosphere presses down on the ocean surface, the low pressure within the eye of the hurricane allows the surface of the ocean to rise.

At the same time, the cyclonic winds push water at a 45-degree-angle to the wind. Hurricane winds move in a circle, thus all the water around the eye is being pushed toward the eye. The result is a mound of water that peaks in height at the edge of the hurricane’s eye.

Ocean currents affected by the earth’s rotation can also magnify the storm surge to a certain degree.

Storm Tide

an image showing water heights increased due to storm surge and high tides with tall waves.

Storm Surge Combines with High Tides and Extreme Waves

A high tide that coincides with the storm surge will magnify the surge by the height of the tide. A five-foot high tide will combine with a 15-foot surge to produce a 20-foot storm tide—water that is 20 feet above the mean sea level.

The coastline along the Gulf of Mexico experiences lower tides than the Atlantic and Pacific Coasts, typical high tides are usually less then two feet above mean sea level. The Atlantic Coast has higher tides, often more than five feet. As a result, the Atlantic Coast experiences greater storm tides than the Gulf Coast.

Battering Waves

Satellite image showing a tropical cyclone with defined rotation and storm bands.

Tropical Cyclone

As the tropical cyclone moves closer to shore, the winds drive high waves ahead of themselves and onto the shore. The waves will combine with the storm surge and storm tide to reach extreme heights and reach much further up the shore than normal. The kinetic energy within the wave combines with the force of the wind that drives it to push the waves further up the shore before they break. Waves can reach far beyond the beach under these circumstances to damage property and threaten lives.

Storm Preparation

Preparation begins long before a storm threatens. Residents of coastal areas should know evacuation routes and make plans that include where they will go if a hurricane or tropical storm forces evacuations in their areas. Once a storm is predicted and forecasters have determined a track, local officials will notify residents of evacuations.

Once the order has been given, evacuate as soon as possible. Routes may become clogged with traffic as the storm nears land and supplies of fuel may also run short.

Inland residents should also make preparations that include topping off stores of food and water and performing preventative maintenance on emergency standby generators. Homes with generators that run on propane should top off their supply if possible. Portable generator owners should also do maintenance and ensure that supplies of gasoline are fresh.

Regardless of location, anyone living where hurricanes or tropical storms threaten should have an emergency preparedness kit and an NOAA weather radio that provides storm updates and emergency information.

Hurricane Preparedness Week: What You Need to Know About Storms

Hurricane Preparedness Week: What You Need to Know About Storms

NOAAs hurricane preparedness week banner

Hurricane Preparedness Week 2014

Few things in nature can match the power, breadth, and scope of a major hurricane. They can span more than a thousand miles, dump rainfall that measures in feet instead of inches, spawn tornadoes, flood miles of countryside, and wash shorelines and small islands into the ocean.

Hurricanes are the ultimate cyclonic storm and it is important to understand how they threaten life and property, and how to prepare your family, home and business when forecasters predict a hurricane will make landfall on a coastline near you.

The week of May 25 – May 31 is National Hurricane Preparedness Week. Are you prepared?

Tropical Cyclones

Satellite imagery of tropical cyclones

Tropical depression (left), Tropical Storm (upper right). Hurricane or Typhoon (lower right)

Low pressure systems over the Atlantic Ocean, Caribbean Sea, or Gulf of Mexico increase in strength and organization. In order of strength, they form tropical depressions, tropical storms, hurricanes, and major hurricanes. They are cyclonic, which means they are rotating masses of air with an upward motion. When a weather system reaches tropical storm strength, the National Hurricane Center gives the storm a name.

Warm water evaporates and the vapor rises until it meets cooler air. The vapor condenses back into water droplets, and as each droplet releases a tiny amount of energy as it turns from a gas back into liquid. That tiny amount of energy pushes on the air and makes it move slightly. By itself, the energy of a single droplet is barely measurable, but combined with the uncountable other droplets doing the same thing, they can move the air at a considerable rate.

The difference in energy between the low pressure at the center of the forming storm and the energy released by the water droplets causes the air to move in a circle around the low pressure center. More water vapor is drawn into the system from the surrounding ocean water and rises to the top to add energy to the storm.

In a sense, the storm feeds on the energy in the warm ocean water.

Immediate Hazards

All tropical cyclones are capable of causing death or injury and property damage. A tropical depression—often a precursor to tropical cyclone formation—has sustained winds up to 38 MPH with gusts capable of snapping trees and heavy rainfall that causes inland flooding.

Extreme wind can shred buildings, topple large trees, and kill or maim people with deadly debris that flies with the wind. Despite media broadcasts that show reporters leaning into the wind and horizontal rain, wind isn’t the greatest worry, but it does help form the second most immediate hazard of a tropical cyclone.

The high winds and low pressure cause two mounds of water to form just ahead of the storm center. When the storm makes landfall, the mounds of water surge onto land and up waterways. The Storm Surge is the second most deadly hazard, second only to Inland Flooding.

Inland flooding is responsible for more property damage and takes more lives than storm surge and extreme winds combined. Torrential rains fall over a relatively short period of time and overwhelm natural and man-made drainages, filling low-lying areas and causing flash floods along waterways and many areas that are normally well above water.


The most important preparation is access to information. An NOAA Weather Radio can provide official information automatically and should be a part of every family’s disaster plan.

Prepare in advance to evacuate if necessary by knowing evacuation routes and having an emergency kit ready in the event an evacuation is necessary. The safest course of action for anyone living on or near the coast when a hurricane threatens is to leave well in advance of the storm.

Food, water, and fuel may be difficult to purchase in the days following a hurricane. Non-perishable foods supplies and enough drinking water for a week will make survival easier in the aftermath of a storm and lessen your dependence on outside sources.

Widespread power outages following a hurricane may last weeks. A source of emergency electricity such as a standby generator can keep refrigerators and freezers running, provide heating or air conditioning, and keep home safety appliances like sump pumps operating during and after the storm. Just as importantly, your emergency supply of electricity keeps you in touch by powering televisions, radios, and charging cell phones.

Atlantic Hurricane Season is Just Three Weeks Away – Are You Ready?

A sattelite view of a tropical cyclone with hurricane or typhoon status showing circular motion and storm bands.

Are You Ready for Hurricane Season?

The Atlantic Hurricane Season begins on June 1 and is far more likely to affect the United States than the Pacific Season. The NHC keeps the Atlantic Graphical Tropical Weather Outlook page on their website updated with storm tracks and weather systems that have even a slight chance of becoming a tropical cyclone.

The Eastern Pacific Hurricane Season begins this week on May 15th. The National Hurricane Center has already tracked one storm that could have escalated into a tropical cyclone as it headed straight for Mexico. Fortunately, it only brought heavy rains to affected areas, but it had a 50 percent chance of becoming a cyclone before it made landfall.

Atlantic Season Storms

The Atlantic Hurricane Season begins on June 1 and ends on November 30. Although tropical cyclones are possible during any month of the year, the official season marks a period when damaging storms are more likely to occur than during other times.

Tropical Cyclones include hurricanes, tropical storms, and tropical depressions. When a weather system reaches tropical storm status, it is named using the next name in the list for that year. The weather systems that produce these storms form mainly off the coast of Africa, in the Caribbean Sea, or in the Gulf of Mexico. Other areas can also produce weather systems that form into tropical cyclones.

Long term forecasts give an overview of what forecasters expect for any given storm season and often do not accurately reflect the actual activity. In 2013, forecasters predicted an above average Atlantic Hurricane Season, but it turned out to be one of the least active seasons on record. The long term forecast for 2014 by University of Colorado researchers indicates a below average season, but only time will reveal the accuracy of that prediction.

Hurricane Preparedness Week

National Hurricane Preparedness Week 2014 Banner for May 25th to May 31st.

National Hurricane Preparedness Week

The NHC will once again host Hurricane Preparedness Week to raise awareness and prepare coastal residents of coastal states for the upcoming season. This year the week runs from May 25 until May 31, with each day highlighting a different aspect of tropical cyclone understanding and how to prepare.

Hurricanes can cause enormous damage to large areas that encompass entire states. Advance preparation before the season arrives helps to ensure that local governments, businesses, and residents are ready for storms that may threaten their areas.

In some cases, only a few days of advance notice is possible as illustrated by Tropical Storm Debbie in 2012.

Tropical Storm Debbie formed out of a depression in the Gulf of Mexico on June 23rd and hit Florida on the 26th. Forecasters expected Debbie to head for Texas or Louisiana, but instead it tracked east. Debbie reached peak intensity with 65-MPH winds despite conditions that discouraged development. In other conditions, Debbie could have been a hurricane when it made landfall instead of a weakening tropical storm.

Even though Debbie continued to weaken as it made landfall, it dumped nearly 30 inches of rain in some places, flooded hundreds of homes, caused widespread power outages, and killed 10 people. State and Interstate Highways were closed due to flooding in Northern Florida with some roads under more than five feet of water. Tornadoes spawned by the storm wreaked additional havoc on buildings and infrastructure.

Home Preparedness

Prepare your home in advance for a hurricane or tropical storm. Determine the amount of plywood you will need to board up your windows and doors and purchase it in advance along with plenty of fasteners to hold the plywood in place. If you have a basement, you probably have a sump pump to help keep it dry. A backup pump can be well worth the money when it prevents your home from flooding.

Don’t forget about an emergency supply of electricity to run your pump, refrigerator, and furnace or air conditioner. A standby generator is your best option because it can run on natural gas from the municipal supply, or propane from your home storage tank. Standby units take time to purchase and install, so don’t wait until a storm threatens. Portable generators are also good options, but they require a steady diet of gasoline—often a hard to find commodity after a devastating storm.

Be prepared for hurricane season and watch for the upcoming blog posts during National Hurricane Preparedness Week.

Generac Promotion Adds Extended Warranty to Standby Generator Packages

Generac 5-year extended warranty promotion ad.

Special Offer: Get a FREE 5 Year Extended Warranty $495.00 VALUE!! Expires 05/05/14 w/ Select Generac Generators

For a limited time beginning Monday, April 21, 2014, Generac’s standby generator packages offered by Norwall PowerSystems will include the Extended Warranty for Generac Power Systems Air-Cooled Generators, a 495-dollar value. The offer includes select standby packages from 8 to 20 kilowatts and includes “bumper-to-bumper” coverage for a five full years.

Generator packages that include the offer are the 20kW, 17kW, 14kW, and 11kW with 200-amp automatic transfer switch, and 17kW, 14kW, and 11kW with 100-amp automatic transfer switch. Also included are the 8kW and 11kW with 50-amp automatic transfer switch.

The Manufacturer’s Warranty as a Purchase Consideration

Anyone considering the purchase of a major appliance will usually factor the manufacturer’s limited consumer warranty in their decision making process. Two products that are otherwise equal in cost, features, and reputation may have different warranty periods or features, and those are an important part of the purchase.

Warranties are a good measure of product reliability. They tell the consumer that the manufacturer stands behind their product and if something goes wrong besides normal wear and tear, the manufacturer will fix it. There are usually limitations. If you crash your car into a wall, your warranty isn’t going to pay for replacing the bumper. Likewise, most product warranties don’t cover maintenance items or maintenance labor such as changing the oil or air filters.

Generac’s Limited Consumer Warranty

Generac’s limited consumer warranty on air-cooled products covers the standby generator for five years or 2000 hours—parts and labor are covered during years one and two, parts only during year three, and engine, rotor, and stator parts only during years four and five.

The standard limited warranty is limited to standby generators installed for residential use by a home that is connected to utility power. Use as a prime power generator or in a location without utility service will void the warranty. Generac air-cooled standby generators are designed to operate during a power outage to provide emergency power until the utility service is restored.

Bumper to Bumper Coverage
