A hurricane is a type of tropical cyclone or severe tropical storm
that forms in the southern Atlantic Ocean, Caribbean Sea, Gulf of
Mexico, and in the eastern Pacific Ocean. A typical cyclone is
accompanied by thunderstorms, and in the Northern Hemisphere, a
counterclockwise circulation of winds near the earth's surface.
All Atlantic and Gulf of Mexico coastal areas are subject to
hurricanes. Parts of the Southwest United States and the Pacific
Coast also experience heavy rains and floods each year from
hurricanes spawned off Mexico. The Atlantic hurricane season lasts
from June to November, with the peak season from mid-August to late
October. The Eastern Pacific hurricane season begins May 15 and ends
November 30.
Hurricanes can cause catastrophic damage to coastlines and several
hundred miles inland. Hurricane can produce winds exceeding 155
miles per hour as well as tornadoes and mircrobursts. Additionally,
hurricanes can create storm surges along the coast and cause
extensive damage from heavy rainfall. Floods and flying debris from
the excessive winds are often the deadly and destructive results of
these weather events. Slow moving hurricanes traveling into
mountainous regions tend to produce especially heavy rain. Excessive
rain can trigger landslides or mud slides. Flash flooding can occur
due to intense rainfall.
Between 1970 and 1999, more people lost their lives from freshwater
inland flooding associated with tropical cyclones than from any
other weather hazard related to such storms.
To prepare for a hurricane, you should take the following
measures:
- To begin preparing, you should build an emergency kit and make a
family communications plan.
- Know your surroundings.
- Learn the elevation level of your property and whether the land is
flood-prone. This will help you know how your property will be
affected when storm surge or tidal flooding are forecasted.
- Identify levees and dams in your area and determine whether they
pose a hazard to you.
- Learn community hurricane evacuation routes and how to find higher
ground. Determine where you would go and how you would get there if
you needed to evacuate.
- Make plans to secure your property:
- Cover all of your home's windows. Permanent storm shutters offer the
best protection for windows. A second option is to board up windows
with 5/8" marine plywood, cut to fit and ready to install. Tape does
not prevent windows from breaking.
- Install straps or additional clips to securely fasten your roof to
the frame structure. This will reduce roof damage.
- Be sure trees and shrubs around your home are well trimmed so they
are more wind resistant.
- Clear loose and clogged rain gutters and downspouts.
- Reinforce your garage doors; if wind enters a garage it can cause
dangerous and expensive structural damage.
- Plan to bring in all outdoor furniture, decorations, garbage cans
and anything else that is not tied down.
- Determine how and where to secure your boat.
- Install a generator for emergencies.
- If in a high-rise building, be prepared to take shelter on or below
the 10th floor.
- Consider building a safe room.
- Hurricanes cause heavy rains that can cause extensive flood damage
in coastal and inland areas. Everyone is at risk and should consider
flood insurance protection. Flood insurance is the only way to
financially protect your property or business from flood
damage.
If a hurricane is likely in your area, you should:
- Listen to the radio or TV for information.
- Secure your home, close storm shutters and secure outdoor objects or
bring them indoors.
- Turn off utilities if instructed to do so. Otherwise, turn the
refrigerator thermostat to its coldest setting and keep its doors
closed.
- Turn off propane tanks
- Avoid using the phone, except for serious emergencies.
- Moor your boat if time permits.
- Ensure a supply of water for sanitary purpose such as cleaning and
flushing toilets. Fill the bathtub and other larger containers with
water.
- Find out how to keep food safe during and after and
emergency.
You should evacuate under the following conditions:
- If you are directed by local authorities to do so. Be sure to follow
their instructions.
- If you live in a mobile home or temporary structure – such shelter
are particularly hazardous during hurricane no matter how well
fastened to the ground.
- If you live in a high-rise building – hurricane winds are stronger
at higher elevations.
- If you live on the coast, on a floodplain, near a river, or on an
island waterway.
If you are unable to evacuate, go to your wind-safe room.
If you do not have one, follow these guidelines:
- Stay indoors during the hurricane and away from windows and glass
doors.
- Close all interior doors – secure and brace external doors.
- Keep curtains and blinds closed. Do not be fooled if there is a
lull; it could be the eye of the storm – winds will pick up
again.
- Take refuge in a small interior room, closet or hallway on the
lowest level.
- Lie on the floor under a table or another sturdy object.
Avoid elevators.
- Continue listening to a NOAA Weather Radio or the local news for the
latest updates.
- Stay alert for extended rainfall and subsequent flooding even after
the hurricane or tropical storm has ended.
- If you have become separated from your family, use your family
communications plan or contact FEMA or the American Red Cross.
- FEMA has established the National Emergency Family Registry and
Locator System (NEFRLS), which has been developed to help reunite
families who are separated during a disaster. The NEFRLS system will
enable displaced individuals the ability to enter personal
information into a website database so that they can be located by
others during a disaster.
- The American Red Cross also maintains a database to help you find
family. Contact the local American Red Cross chapter where you are
staying for information. Do not contact the chapter in the disaster
area.
- If you evacuated, return home only when officials say it is
safe.
- If you cannot return home and have immediate housing needs. Text
SHELTER + your ZIP code to 43362 (4FEMA) to find the nearest shelter
in your area (example: shelter 12345).
- For those who have longer-term housing needs, FEMA offers several
types of assistance, including services and grants to help people
repair their homes and find replacement housing. Apply for
assistance or search for information about housing rental
resources
- Drive only if necessary and avoid flooded roads and washed-out
bridges. Stay off the streets. If you must go out watch for fallen
objects; downed electrical wires; and weakened walls, bridges,
roads, and sidewalks.
- Keep away from loose or dangling power lines and report them
immediately to the power company.
- Walk carefully around the outside your home and check for loose
power lines, gas leaks and structural damage before entering.
- Stay out of any building if you smell gas, floodwaters remain around
the building or your home was damaged by fire and the authorities
have not declared it safe.
- Inspect your home for damage. Take pictures of damage, both of the
building and its contents, for insurance purposes. If you have any
doubts about safety, have your residence inspected by a qualified
building inspector or structural engineer before entering.
- Use battery-powered flashlights in the dark. Do NOT use candles.
Note: The flashlight should be turned on outside before entering -
the battery may produce a spark that could ignite leaking gas, if
present.
- Watch your pets closely and keep them under your direct
control.
- Watch out for wild animals, especially poisonous snakes. Use a stick
to poke through debris.
- Avoid drinking or preparing food with tap water until you are sure
it's not contaminated.
- Check refrigerated food for spoilage. If in doubt, throw it out.
Wear protective clothing and be cautious when cleaning up to avoid
injury.
- Use the telephone only for emergency calls.
- NEVER use a generator inside homes, garages, crawlspaces, sheds, or
similar areas, even when using fans or opening doors and windows for
ventilation. Deadly levels of carbon monoxide can quickly build up
in these areas and can linger for hours, even after the generator
has shut off.
