...Continuing Severe Weather Awareness Week for Louisiana...

Today`s topic is Flash Flood Safety...

As part of Louisiana Severe Weather Awareness Week, the National
Weather Service wants you to be aware of the dangers of the
number one storm killer, flash flooding.

A flash flood is a rapid rise of water along a stream, or in a low
lying urban area. Flash flooding can result from slow moving
thunderstorms, from numerous thunderstorms which develop
repeatedly over the same area, and from heavy rains associated
with tropical cyclones. These floods may develop within minutes,
depending on the intensity of rainfall, the topography, soil
conditions, and ground cover.

Few people realize the true power of water. Rapidly moving flood
waters only six inches deep can knock an adult off their feet. Two
feet of water can lift approximately 3000 pounds, which is the
weight of an average sized vehicle. Vehicles crossing a flooded
roadway can lose traction with the road, actually floating in some
cases. In some cases, water can erode the earth underneath a road,
causing it to wash out. If a vehicle becomes overturned, it can
fill with water, endangering the lives of its occupants. Flash
flood statistics indicate that half of the annual flood related
fatalities are vehicle related.

When flash floods occur in rural areas, people who enjoy hunting,
camping, and fishing need to stay away from streams if strong
thunderstorms have occurred. Water in streams can rise over ten
feet in less than an hour with the heavy rainfall.

So how can we stay safe from the dangers associated with flash

Monitor weather radio and pay close attention to flash flood
warnings issued by the National Weather Service.

Be especially cautions at night when it is more difficult to
recognize the dangers of flash flooding.

Avoid low lying areas that are prone to flooding. Don`t camp or
park your vehicle along streams and washes. If your vehicle is
suddenly caught in rising water, leave it immediately and move to
higher ground.

Lastly, never attempt to cross areas where water covers the road.
Remember the first safety rule of flash flooding, turn around,
don`t drown.
