FLOODS AND FLASH
FLOOD SAFETY
Prolonged rainfall can cause a river, stream or other waterway to
overflow its banks. This slow-rising flood can take several days before
the flooding begins. Most communities in the United States can experience
some kind of flooding. Floods can happen anytime during the year, such as
after winter snowmelts, spring thunderstorms, and fall hurricanes.
Another type of flood that comes swiftly and usually with little warning
is the flash flood. Flash floods are rapidly developing floods that can
happen with little or no warning after an intense rainfall, a severe
thunderstorm, or a dam, levee or dike breaks. Flash floods can occur in or
near mountainous areas, on small streams and even in large cities. Water
levels can suddenly rise in heavy rainstorms, leaving little time before
small streams, desert-washes and drainage ditches become raging rivers.
Sometimes a flash flood can unleash its deadly force in just a few
minutes.
SAFETY TIPS
BE READY BEFORE THE FLOOD
- Know your area's flood risks. If you're not certain contact the local
National Weather Service office, Red Cross chapter, or Emergency
Management Agency. (Civil Defense or F.E.M.A.)
- If you live in an area that could flood, find out if flood insurance
is available, what provisions it affords, and what... if any, additional
coverage's are afforded above and beyond your insurance by local or
national programs.
- Keep insurance policies, documents, and valuables in a safe-deposit
box.
- Prepare a family evacuation plan. Do a practice run through once a
year.
- Prepare instructions on how to turn off utilities.
- Watch the Weather Channel; listen to your local radio or national
weather service broadcasts (accessible through readily available monitor
radios), to keep track of weather patterns and know the risks and
hazards as they develop. Flash Flooding can happen quickly so you'll
want to pay attention during heavy rain events in your area.
- Keep your car's gas tank filled, and your fuel deliveries
current. Floods can cut power and knock out your fuel station's ability
to pump gas.
- Keep first aid supplies available.
- Keep a portable radio, flashlight, and portable food supplies that
don't require refrigeration available. The power could be cut off for
days.
DURING A FLOOD WARNING
A flood WARNING means flooding is occurring or will occur soon.
If a flood WARNING is issued for your area, go to safety.
- Listen to local TV and radio stations for vital information.
- Be careful moving furniture and valuable to higher ground. Rushing to
move things can lead to injury and heart attack. Have someone help you.
Certainly save your life and family first before your things.
- Turn off your utilities as best you can if your home is likely to be
flooded.
- Evacuate if you are told to do so.
- Don't cross barricades that are there to protect you from the flood
waters.
- Don't drive, walk or wade in flood waters. Keep your children away
from the flood waters due to disease and the threat of getting washed
away.
DURING A FLASH FLOOD WATCH
A flash flood WATCH means flash flooding is possible in your
area. If a flash flood WATCH is issued for your country or parish,
get set.
- Stay tuned to TV and radio for vital local information.
- Keep alert for signs of flash flooding, such as intense rainfall or
rising waters. If you suspect flooding has started, GO TO SAFETY
IMMEDIATELY. DON'T WAIT!
DURING A FLASH FLOOD WARNING
A flash flood WARNING means you may have only seconds to escape.
A flash flood can happen so rapidly that you may NOT get a warning. If a
flash flood WARNING is issued for your county, parish, or town
GO TO SAFETY IMMEDIATELY.
- Leave low-lying areas immediately.
- If you are driving in a desert or canyon area and you encounter a
flash flood, get out of your car and climb to higher ground immediately.
Don't get swept away by the flood. Don't try to outrun a flash flood in
your car. Climb to safety immediately.
- Stay away from storm drains and irrigation ditches. You could easily
get swept into one by the fast moving water.
- Don't ever approach and drive on flood waters covering roads or
bridges. The water has a force far greater than the power than you might
think. It only takes a few feet of rushing water to sweep your car away
or tip it over. Also, the roadway may have washed out and the rushing
water may be deeper than you think.
AFTER THE FLOOD OR FLASH FLOOD
- Throw out and start fresh with any food stuffs that have come into
contact with flood waters. Also, any food that hasn't been able to hold
in refrigeration.
- Tests drinking water for potability. Water lines and wells could be
spoiled by muddy flood waters full of debris and sewer effluent making
them dangerous to drink.
- Be careful with live electrical equipment and gas stoves. Both may be
weakened or damaged resulting in an explosion or electrical discharge.
Have all utilities checked by proper authorities.
- Report damaged utilities and power lines to be fixed.
- Ensure the weather threat that caused the flooding is over. More
flooding could occur in an on-going heavy rain weather event.
