EMERGENCY DISASTER PREPAREDNESS
HURRICANES
Hurricanes, also known as typhoons, are tropical cyclones with
torrential rains and sustained winds of 74 miles per hour or greater which
blow in a counter-clockwise direction around a center "eye."
If the eye passes directly overhead, there will be a lull in the
wind lasting from a few minutes to half an hour.
On the other side of the eye, the winds will return rapidly to
hurricane force and blow from the opposite direction. Hurricane winds can
exceed 155 miles per hour and severely affect areas hundreds of miles
inland.
Hurricanes form over water as tropical storms before gathering enough
force to reach land. As
hurricanes approach the coast, a huge dome of water called a storm surge
crashes into the coastline, causing major damage to everything in its
path. About nine out of ten
people killed in hurricanes are victims of the storm surge. Hurricanes also spawn tornadoes and cause severe flooding
from heavy rains. All coastal
states, particularly Atlantic and Gulf Coastal States, are threatened by
hurricanes. Hurricane season
usually extends from June through November.
Hurricanes are classified into the five categories, based on their wind
speeds, central pressure, and damage potential.
The groupings are:
Category 1: winds
of 74 to 95 MPH and a storm surge of 4-5 feet above the mean high tide.
Category 2: winds
of 96 to 110 MPH and a storm surge of 6-8 feet above the mean high tide.
Category 3: winds
of 111 to 130 MPH and a storm surge of 9-12 feet above the mean high tide.
Category 4: winds
of 131 to 155 MPH and a storm surge of 13-18 feet above the mean high
tide.
Category 5: winds
over 155 MPH and a storm surge over 18 feet above the mean high tide.
It is important to know the terms used to describe hurricanes and like
threats. They are:
Hurricane Watch – meteorological conditions make the
appearance of a hurricane within 36 hours likely. Stay tuned to radio or television reports.
Hurricane Warning – a hurricane is expected within 24 hours.
Tropical Storm Watch – meteorological conditions favor the
appearance of a tropical storm (wind speeds between 39 and 74 mph).
Stay tuned to radio or television reports.
Tropical Storm Warning – a tropical storm is expected within
24 hours.
Preparation for a hurricane is the best method for minimizing injury or
damage during one. There will
be little time to move to protected areas once a hurricane is in the
immediate vicinity. Follow
these important steps to prepare yourself and your family for a hurricane:
- Purchase
a National Oceanic and Atmospheric Administration Weather Radio with a
battery backup and tone-alert feature.
A NOAA (pronounced "Noah") radio will automatically alert
you when a Hurricane Watch or Warning has been issued. Also purchase a battery-powered commercial radio and
extra batteries as well.
- When
skies are threatening or a hurricane watch has been issued for the
Florence area, listen to NOAA radio or local radio or television
newscasts for the latest information and special instructions from
local officials.
- Learn
community evacuation procedures and routes. Determine where you would go and how you would get there
if you needed to evacuate. Keep
your car fueled and in good condition in case evacuation is required.
- Determine
places to seek shelter during a hurricane and practice going there
with your family. A
basement, storm cellar, or interior room or hallway on the lowest
floor of your home is the best place.
If you live in a low-lying area, a beach front, or a mobile
home, determine a safe place outside of the area to take shelter, as
these areas are very prone to hurricane damage.
- Talk
to your family about hurricanes.
Plan a place to meet your family in case you are separated.
Determine the needs of family members or neighbors who may need
your help in a hurricane. Choose
an out-of-state contact for everyone to call to say they are okay.
- Gather
emergency supplies and have them on hand in case a hurricane
approaches. Keep tools,
flashlights, a portable radio, batteries, a First Aid kit, fresh
water, and non-perishable foods handy.
- Make
plans to protect your property. Permanent
storm shutters offer the best protection for windows.
A second option is to purchase 5/8" marine plywood, cut to
fit and ready to install. Also,
secure loose objects in your yard and windowsills which can become
airborne missiles in a hurricane.
Moor boats securely or move them to a safe place well in
advance of a storm.
- Know
how to shut off utilities. Know
where gas pilots, water mains, and circuit breakers are located and
how the heating and air-conditioning system works.
- Have
your home inspected for compliance with local building codes.
Many homes destroyed by hurricanes are destroyed because they
were not constructed according to building codes.
- Much
of the damage caused by hurricanes comes from flooding.
Consider purchasing flood insurance.
Plan ahead, as there is normally a five-day waiting period
before flood insurance takes effect.
- Know
the locations of shelters in places where you and your family spend
time, such as public buildings, nursing homes, and shopping centers.
Ask whether your children's schools have been inspected for
shelter space by a registered engineer or architect.
If a hurricane is threatening the Florence area, the most important
thing to do is listen for information and instructions on radio or
television newscasts or NOAA Radio. These
emergency broadcasts will tell you whether you should prepare to evacuate
or seek shelter in or near your own home. Get together with family members to talk about what needs to
be done. Make sure everyone
knows where to meet and who to call in case you are separated from one
another. Determine the needs
of family members or neighbors who may need your help.
Secure your home. Close
storm shutters and board up windows. Secure outdoor objects or bring them indoors.
Moor your boat if time permits.
Gather your emergency supplies and make arrangements for pets, as
they are not allowed in emergency shelters.
If instructed, turn off utilities at the main valves.
If you are instructed to evacuate, follow instructions as to where to
go and the routes you should take. Be
sure that your car is fueled and you have emergency supplies with you.
Leave immediately to avoid being marooned by flooded roads and
fallen trees, especially if you live in a low-lying area, a beach front,
or a mobile home. Stay away from coastal areas, river banks, and streams.
If you have time, tell others where you are going.
If you are not required to evacuate, stay indoors during the hurricane
and away from windows. In a
house or small building, go to the basement or storm cellar.
If there is no basement, go to an interior room on the lower level
– closets and interior hallways work well.
In a high-rise building, go to a small, interior room or hallway on
the lowest floor possible. Be
sure not to be directly under heavy appliances on an upper floor.
Do not be fooled if there is a lull in the storm – it most likely
means you are in the eye of the storm, in which case winds will pick up
again shortly. Avoid using
the phone except for serious emergencies.
Local authorities need first priority on telephone lines.
After a hurricane, danger and injury are still possibilities.
It is extremely important to keep the following information and
safety standards in mind:
- If
you are in a safe location, stay where you are until local authorities
give the okay to return.
- Keep
tuned to local radio or television stations for information such as
caring for your family, finding medical help, or applying for
financial assistance.
- Talk
with your children about what has happened and how they can help
during the recovery. Being
involved will help them deal with the situation.
Consider the needs of your neighbors. People often become isolated during hurricanes.
- Stay
away from disaster areas unless local authorities request volunteers.
If you are needed, bring your own drinking water, food, and
sleeping gear. Another
way to help is to donate money to a recognized disaster relief
organization. Do not
donate food, clothing, or other personal items unless they are
specifically requested.
- Drive
only when necessary and be especially careful. The streets will be filled with debris and downed power
lines. Roads may be
undermined and collapse under the weight of a car.
- Stay
away from coastal areas, river banks, and streams until potential
flooding has passes. Report
broken gas, sewer, or water mains.
Do not let children play in the street due to possible health
hazards from overflow of raw sewage from sewer manholes.
- Contact
your insurance agent. An
adjuster will be assigned to visit your home.
Take photos or videotape of the damage. Separate damaged and undamaged belongings.
Locate your financial records.
Keep detailed records of cleanup costs.
- If
the electricity goes out, use flashlights or battery powered lanterns.
Do not use candles, matches or open flames indoors after the
hurricane because of possible gas leaks.
- Check
your home, especially roofs and chimneys, for structural damage.
The initial check should be made from a distance.
If you have any doubts about safety, have your home inspected
by a professional before entering.
Wear sturdy shoes in areas covered with fallen debris and
broken glass.
- Clean
up spilled medicines, bleaches, gasoline and other flammable liquids
inside buildings. If you
smell gas or hear a hissing or blowing sound, open a window and leave
the building. Shut off
the main gas valve outside, if you can.
Report the leak to the gas company from a neighbor's house.
Stay out of the building.
If you shut off the gas supply at the main valve, you will need
a professional to turn it back on.
- Visually
inspect utility lines and appliances for damage. If there is electrical damage, switch off all power at
the main fuse box or circuit breaker.
If your home has suffered water damage, do not turn on the
electricity until the circuits have been checked by a qualified
electrician – moisture may still be trapped within electrical boxes,
receptacles, motors, and switches.
- If
water or sewer pipes are damaged, shut off the water supply at the
main valve. Do not flush
toilets. If water is cut
off, use water from the water heater.
