Every state in the U.S. has experienced tornadoes and severe weather, and although some more than others, everyone is at risk. You can take steps to prepare for when severe weather strikes in your area.

Before

• Continually monitor the media – Be aware of storm's which could impact your area.
• Know what type of severe weather is common for your area.
• Know where to shelter (basement, interior room, bathroom, closet, etc).
• Know how to shut off utilities including electric, water and gas, to your home.

During

• Keep an eye on the sky. Look for darkening skies, flashes of light or increasing wind. Listen for the sound of thunder.
• Heed shelter or evacuation requests made by officials.
• Gather family members, bring pets indoors and have your emergency supply kit ready.
• If it has been raining hard for several hours, or steadily raining for several days, be alert to the possibility of a flood.
• Do not walk through flowing water. Drowning is the number one cause of flood deaths.

After

• Stay off roads to allow emergency crews to clear roads and provide emergency assistance.
• Use care around downed power lines. Assume a downed wire is a live wire.
• Watch out for overhead hazards such as broken tree limbs, wires and other debris.
• Listen to media reports and/or local authorities about whether your community water supply is safe to drink and other instructions.
• Take photographs/videos of damage as soon as possible. Contact your insurance company to file a claim.

Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature.  Most heat disorders occur because the victim has been overexposed to heat or has over-exercised for his or her age and physical condition. Older adults, young children and those who are sick or overweight are more likely to succumb to extreme heat.  Conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor air quality. Consequently, people living in urban areas may be at greater risk from the effects of a prolonged heat wave than those living in rural areas. Also, asphalt and concrete store heat longer and gradually release heat at night, which can produce higher nighttime temperatures known as the "urban heat island effect."  A heat wave is an extended period of extreme heat, and is often accompanied by high humidity. These conditions can be dangerous and even life-threatening for humans who don't take the proper precautions.

Before Extreme Heat

To prepare for extreme heat, you should:

• To begin preparing, you should build an emergency kit and make a family communications plan.
• Install window air conditioners snugly; insulate if necessary.
• Check air-conditioning ducts for proper insulation.
• Install temporary window reflectors (for use between windows and drapes), such as aluminum foil-covered cardboard, to reflect heat back outside.
• Weather-strip doors and sills to keep cool air in.
• Cover windows that receive morning or afternoon sun with drapes, shades, awnings, or louvers. (Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.)
• Keep storm windows up all year.
• Listen to local weather forecasts and stay aware of upcoming temperature changes.
• Know those in your neighborhood who are elderly, young, sick or overweight. They are more likely to become victims of excessive heat and may need help.
• Be aware that people living in urban areas may be at greater risk from the effects of a prolonged heat wave than are people living in rural areas.
• Get trained in first aid to learn how to treat heat-related emergencies.

During

What you should do if the weather is extremely hot:

• Listen to NOAA Weather Radio for critical updates from the National Weather Service (NWS).
• Never leave children or pets alone in closed vehicles.
• Stay indoors as much as possible and limit exposure to the sun.
• Stay on the lowest floor out of the sunshine if air conditioning is not available.
• Postpone outdoor games and activities.
• Consider spending the warmest part of the day in public buildings such as libraries, schools, movie theaters, shopping malls, and other community facilities. Circulating air can cool the body by increasing the perspiration rate of evaporation.
• Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do so by a physician.
• Drink plenty of water; even if you do not feel thirsty. Avoid drinks with caffeine. Persons who have epilepsy or heart, kidney, or liver disease; are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
• Limit intake of alcoholic beverages.
• Dress in loose-fitting, lightweight, and light-colored clothes that cover as much skin as possible. Avoid dark colors because they absorb the sun’s rays.
• Protect face and head by wearing a wide-brimmed hat.
• Avoid strenuous work during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.
• Check on family, friends, and neighbors who do not have air conditioning and who spend much of their time alone.
• Avoid extreme temperature changes.

All thunderstorms are dangerous. Every thunderstorm produces lightning. While lightning fatalities have decreased over the past 30 years, lightning continues to be one of the top three storm-related killers in the United States. In 2010 there were 29 fatalities and 182 injuries from lightning. Although most lightning victims survive, people struck by lightning often report a variety of long-term, debilitating symptoms.

Other associated dangers of thunderstorms include tornadoes, strong winds, hail and flash flooding. Flash flooding is responsible for more fatalities – more than 140 annually – than any other thunderstorm-associated hazard. Dry thunderstorms that do not produce rain that reaches the ground are most prevalent in the western United States. Falling raindrops evaporate, but lightning can still reach the ground and can start wildfires.

Before

To prepare for a thunderstorm, you should do the following:

• To begin preparing, you should build an emergency kit and make a family communications plan.
• Remove dead or rotting trees and branches that could fall and cause injury or damage during a severe thunderstorm.
• Postpone outdoor activities.
• Secure outdoor objects that could blow away or cause damage.
• Get inside a home, building, or hard top automobile (not a convertible). Although you may be injured if lightning strikes your car, you are much safer inside a vehicle than outside.
• Remember, rubber-soled shoes and rubber tires provide NO protection from lightning. However, the steel frame of a hard-topped vehicle provides increased protection if you are not touching metal.
• Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades or curtains.
• Unplug any electronic equipment well before the storm arrives.

During

If thunderstorm and lightning are occurring in your area, you should:

• Use your battery-operated NOAA Weather Radio for updates from local officials.
• Avoid contact with corded phones and devices including those plugged into electric for recharging.  Cordless and wireless phones not connected to wall outlets are OK to use.
• Avoid contact with electrical equipment or cords. Unplug appliances and other electrical items such as computers and turn off air conditioners. Power surges from lightning can cause serious damage.
• Avoid contact with plumbing. Do not wash your hands, do not take a shower, do not wash dishes, and do not do laundry. Plumbing and bathroom fixtures can conduct electricity.
• Stay away from windows and doors, and stay off porches.
• Do not lie on concrete floors and do not lean against concrete walls.
• Avoid natural lightning rods such as a tall, isolated tree in an open area.
• Avoid hilltops, open fields, the beach or a boat on the water.
• Take shelter in a sturdy building. Avoid isolated sheds or other small structures in open areas.
• Avoid contact with anything metal—tractors, farm equipment, motorcycles, golf carts, golf clubs, and bicycles.
• If you are driving, try to safely exit the roadway and park. Stay in the vehicle and turn on the emergency flashers until the heavy rain ends. Avoid touching metal or other surfaces that conduct electricity in and outside the vehicle.

After 

If lightning strikes you or someone you know, call 9-1-1 for medical assistance as soon as possible. The following are things you should check when you attempt to give aid to a victim of lightning:

• Breathing - if breathing has stopped, begin mouth-to-mouth resuscitation.
• Heartbeat - if the heart has stopped, administer CPR.
• Pulse - if the victim has a pulse and is breathing, look for other possible injuries. Check for burns where the lightning entered and left the body. Also be alert for nervous system damage, broken bones and loss of hearing and eyesight.

After the storm passes remember to:

• Never drive through a flooded roadway. Turn around, don’t drown!
• Stay away from storm-damaged areas to keep from putting yourself at risk from the effects of severe thunderstorms.
• Continue to listen to a NOAA Weather Radio or to local radio and television stations for updated information or instructions, as access to roads or some parts of the community may be blocked.
• Help people who may require special assistance, such as infants, children and the elderly or those with access or functional needs.
• Stay away from downed power lines and report them immediately.
• Watch your animals closely. Keep them under your direct control.

While the danger from winter weather varies across the country, nearly all Americans, regardless of where they live, are likely to face some type of severe winter weather at some point in their lives. Winter storms can range from a moderate snow over a few hours to a blizzard with blinding, wind-driven snow that lasts for several days. Many winter storms are accompanied by dangerously low temperatures and sometimes by strong winds, icing, sleet and freezing rain.

One of the primary concerns is the winter weather's ability to knock out heat, power and communications services to your home or office, sometimes for days at a time. Heavy snowfall and extreme cold can immobilize an entire region.

The National Weather Service refers to winter storms as the “Deceptive Killers” because most deaths are indirectly related to the storm. Instead, people die in traffic accidents on icy roads and of hypothermia from prolonged exposure to cold. It is important to be prepared for winter weather before it strikes.

Before

To prepare for a winter storm you should do the following:

• Before winter approaches, add the following supplies to your emergency kit:
• Rock salt or more environmentally safe products to melt ice on walkways. Visit the Environmental Protection Agency for a complete list of recommended products.
• Sand to improve traction.
• Snow shovels and other snow removal equipment.
• Sufficient heating fuel. You may become isolated in your home and regular fuel sources may be cut off. Store a good supply of dry, seasoned wood for your fireplace or wood-burning stove.
• Adequate clothing and blankets to keep you warm.
• Make a Family Communications Plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together and what you will do in case of an emergency.
• A NOAA Weather Radio broadcasts alerts and warnings directly from the NWS for all hazards. You may also sign up in advance to receive notifications from your local emergency services.
• Download FEMA’s Be Smart. Know Your Alerts and Warnings for a summary of notifications at: www.ready.gov/prepare. Free smart phone apps, such as those available from FEMA and the American Red Cross, provide information about finding shelters, providing first aid, and seeking assistance for recovery.
• Minimize travel. If travel is necessary, keep a disaster supplies kit in your vehicle.
• Bring pets/companion animals inside during winter weather. Move other animals or livestock to sheltered areas with non-frozen drinking water.

During

• Stay indoors during the storm.
• Walk carefully on snowy, icy, walkways.
• Avoid overexertion when shoveling snow. Overexertion can bring on a heart attack—a major cause of death in the winter. Use caution, take breaks, push the snow instead of lifting it when possible, and lift lighter loads.
• Keep dry. Change wet clothing frequently to prevent a loss of body heat. Wet clothing loses all of its insulating value and transmits heat rapidly.
• Signs of Frostbite: Occurs when the skin and body tissue just beneath it freezes. Loss of feeling and white or pale appearance in extremities, such as fingers, toes, earlobes, face, and the tip of the nose.
• What to Do: Cover exposed skin, but do not rub the affected area in an attempt to warm it up. Seek medical help immediately.
• Signs of Hypothermia: Dangerously low body temperature. Uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and apparent exhaustion.
• What to Do: If symptoms of hypothermia are detected take the person’s temperature. If it is below 95°, seek medical attention immediately. Get the victim to a warm location. Remove wet clothing. Warm the center of the body first by wrapping the person in blankets or putting on dry clothing. Give warm, non-alcoholic beverages if the victim is conscious. Seek medical help immediately.
• The U.S. Centers for Disease Control and Prevention (CDC) recommends, if you detect symptoms of frostbite, seek medical care. Because frostbite and hypothermia both result from exposure, first determine whether the victim also shows signs of hypothermia. Hypothermia is a more serious medical condition and requires emergency medical assistance.
• Drive only if it is absolutely necessary. If you must drive: travel in the day; don’t travel alone; keep others informed of your schedule; stay on main roads and avoid back road shortcuts.
• Let someone know your destination, your route, and when you expect to arrive. If your car gets stuck along the way, help can be sent along your predetermined route.
• If the pipes freeze, remove any insulation or layers of newspapers and wrap pipes in rags. Completely open all faucets and pour hot water over the pipes, starting where they were most exposed to the cold (or where the cold was most likely to penetrate).
• Maintain ventilation when using kerosene heaters to avoid build-up of toxic fumes. Refuel kerosene heaters outside and keep them at least three feet from flammable objects.
• Conserve fuel, if necessary, by keeping your residence cooler than normal. Temporarily close off heat to some rooms.
• If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55ºF.

After

• If your home loses power or heat for more than a few hours or if you do not have adequate supplies to stay warm in your home overnight, you may want to go to a designated public shelter if you can get there safely. Text SHELTER + your ZIP code to 43362 (4FEMA) to find the nearest shelter in your area (e.g., SHELTER20472)
• Bring any personal items that you would need to spend the night (such as toiletries, medicines). Take precautions when traveling to the shelter. Dress warmly in layers, wear boots, mittens, and a hat.
• Continue to protect yourself from frostbite and hypothermia by wearing warm, loose-fitting, lightweight clothing in several layers. Stay indoors, if possible.

Floods are very common hazards in the U.S. and can happen very slowly or very fast. Floods can be caused by excessive rain causing rivers and creeks to overflow. They can be caused by melt off from deep snow or damn and levee failure.

Here are some safety tips to prepare for rising water—and what to do once a flood has begun.

Before a Flood

• Avoid building in a floodplain.
• Construct barriers (levees, beams, floodwalls) to stop floodwater from entering your home.
• Seal walls in basements with waterproofing compounds to avoid seepage.
• If a flood is likely in your area, listen to the radio or television for information.
• Know the difference between a flood watch and a flood warning. A watch means flooding is possible. A warning means flooding is occurring or will occur soon.

When a Flood is Imminent

• Be prepared! Pack a bag with important items in case you need to evacuate. Don't forget to include needed medications.
• If advised to evacuate your home, do so immediately.
• If there is any possibility of a flash flood, move immediately to higher ground.
• If possible, bring in outdoor furniture and move essential items to an upper floor.
• Turn off utilities at the main switches or valves if instructed to do so. Disconnect electrical appliances.

During a Flood

• Do not walk through moving water. As little as 6 inches (15 centimeters) of moving water can make you fall.
• If you have to walk in water, wherever possible, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.
• Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground if you can do so safely.
• Do not touch electrical equipment if you are wet or standing in water.

After a Flood

• Listen for news reports to learn whether the community's water supply is safe to drink.
• Avoid floodwaters; water may be contaminated by oil, gasoline, or raw sewage. Water may also be electrically charged from underground or downed power lines.
• Avoid moving water.
• Be aware of areas where floodwaters have receded. Roads may have weakened and could collapse under the weight of a car.
• Stay away from downed power lines, and report them to the power company.
• Return home only when authorities indicate it is safe.
• Stay out of any building if it is surrounded by floodwaters.
• Service damaged septic tanks, cesspools, pits, and leaching systems as soon as possible. Damaged sewage systems are serious health hazards.
• Clean and disinfect everything that got wet. Mud left from floodwater can contain sewage and chemicals.

Chemicals are found everywhere. They purify drinking water, increase crop production and simplify household chores. But chemicals also can be hazardous to humans or the environment if used or released improperly. Hazards can occur during production, storage, transportation, use or disposal. You and your community are at risk if a chemical is used unsafely or released in harmful amounts into the environment where you live, work or play.  Hazardous materials in various forms can cause death, serious injury, long-lasting health effects and damage to buildings, homes and other property.

Many products containing hazardous chemicals are used and stored in homes routinely. These products are also shipped daily on the nation's highways, railroads, waterways and pipelines.  Chemical manufacturers are one source of hazardous materials, but there are many others, including service stations, hospitals and hazardous materials waste sites.  Varying quantities of hazardous materials are manufactured, used or stored at an estimated 4.5 million facilities in the United States--from major industrial plants to local dry cleaning establishments or gardening supply stores.  Hazardous materials come in the form of explosives, flammable and combustible substances, poisons and radioactive materials. These substances are most often released as a result of transportation accidents or because of chemical accidents in plants.

Before a Hazardous Materials Incident

Many communities have Local Emergency Planning Committees (LEPCs) whose responsibilities include collecting information about hazardous materials in the community and making this information available to the public upon request. The LEPCs also are tasked with developing an emergency plan to prepare for and respond to chemical emergencies in the community. Ways the public will be notified and actions the public must take in the event of a release are part of the plan. Contact the LEPCs to find out more about chemical hazards and what needs to be done to minimize the risk to individuals and the community from these materials. Your local emergency management office can provide contact information on the LEPCs. 

The following are things you can do to protect yourself, your family and your property from the effects of a hazardous materials incident:

• Build an Emergency Supply Kit, which includes items like non-perishable food, water, a battery-powered or hand-crank radio, extra flashlights and batteries. You should add plastic sheeting, duct tape and scissors to the kit in order be better prepared for a hazardous materials incident. You may want to prepare a portable kit and keep it in your car in case you are told to evacuate.
• Make a Family Emergency Plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together and what you will do in case of an emergency.

During a Hazardous Materials Incident

Listen to local radio or television stations for detailed information and instructions. Follow the instructions carefully. You should stay away from the area to minimize the risk of contamination. Remember that some toxic chemicals are odorless.

If you are asked to evacuate

• Do so immediately.
• Stay tuned to a radio or television for information on evacuation routes, temporary shelters, and procedures.
• Follow the routes recommended by the authorities--shortcuts may not be safe. Leave at once.
• If you have time, minimize contamination in the house by closing all windows, shutting all vents, and turning off attic fans.
• Take pre-assembled disaster supplies.
• Remember to help your neighbors who may require special assistance--infants, elderly people and people with access and functional needs.

If you are caught outside

• Stay upstream, uphill, and upwind! In general, try to go at least one-half mile (usually 8-10 city blocks) from the danger area. Move away from the accident scene and help keep others away.
• Do not walk into or touch any spilled liquids, airborne mists, or condensed solid chemical deposits. Try not to inhale gases, fumes and smoke. If possible, cover mouth with a cloth while leaving the area.
• Stay away from accident victims until the hazardous material has been identified.
• In a motor vehicle
• Stop and seek shelter in a permanent building. If you must remain in your car, keep car windows and vents closed and shut off the air conditioner and heater.

If you are requested to stay indoors

• Bring pets inside.
• Close and lock all exterior doors and windows. Close vents, fireplace dampers, and as many interior doors as possible.
• Turn off air conditioners and ventilation systems. In large buildings, set ventilation systems to 100 percent recirculation so that no outside air is drawn into the building. If this is not possible, ventilation systems should be turned off.
• Go into the pre-selected shelter room. This room should be above ground and have the fewest openings to the outside.
• Seal gaps under doorways and windows with wet towels or plastic sheeting and duct tape.
• Seal gaps around window and air conditioning units, bathroom and kitchen exhaust fans, and stove and dryer vents with duct tape and plastic sheeting, wax paper or aluminum wrap.
• Use material to fill cracks and holes in the room, such as those around pipes.
• If gas or vapors could have entered the building, take shallow breaths through a cloth or a towel. Avoid eating or drinking any food or water that may be contaminated.

After a Hazardous Materials Incident

The following are guidelines for the period following a hazardous materials incident:

• Go to a designated public shelter if you have been told to evacuate or you feel it is unsafe to remain in your home. Text SHELTER + your ZIP code to 43362 (4FEMA) to find the nearest shelter in your area (example: shelter 12345).
• Act quickly if you have come in to contact with or have been exposed to hazardous chemicals.
• Follow decontamination instructions from local authorities. You may be advised to take a thorough shower or you may be advised to stay away from water and follow another procedure.
• Seek medical treatment for unusual symptoms as soon as possible.
• Place exposed clothing and shoes in tightly sealed containers. Do not allow them to contact other materials. Call local authorities to find out about proper disposal.
• Advise everyone who comes in to contact with you that you may have been exposed to a toxic substance.
• Listen to local radio or television stations for the latest emergency information.
• Help a neighbor who may require special assistance - infants, elderly people and people with access and functional needs. People who care for them or who have large families may need additional assistance in emergency situations.
• Return home only when authorities say it is safe. Open windows and vents and turn on fans to provide ventilation.
• Find out from local authorities how to clean up your land and property.
• Report any lingering vapors or other hazards to your local emergency services office.
