FLOODS Floods are one of the most common hazards in the United States. Floods can develop slowly, over a period of days, or within a few minutes, without any visible signs of rain, such as with flash floods. It is a good idea to be aware of flood hazards no matter where you live, but especially if you live in a low lying area. Even very small streams, dry steam beds, or low lying ground that appears harmless in dry weather can flood. What to do in a heavy rainfall: Stay away from stream beds. Use your map. Know whether you are on low ground or below a dam. Move to higher ground. Many roads and trails parallel existing drainage patterns, and may be swept away by flood waters. Stay out of these low lying areas when there is a risk of flooding. Never attempt to outrun a flood on foot or in your vehicle, climb to safety. Avoid driving through flooded areas. Flood waters can rise quickly and sweep vehicles away. If an area is flooded, consider taking an alternate route. Before a flood: Know the National Weather Service terms: Flash flood watch means that heavy rains are occurring or may occur, and may cause flash flooding. Be Alert. Flash flood warning means that flash flooding is occurring or imminent. If you live in the warning area, you should act immediately. During a flood: Be aware of possible flash flooding hazards. If there is any possibility of a flash flood, move immediately to higher ground. Do not wait for instructions to move. Listen to radio or television stations for local information. Be aware of streams, drainage channels, canyons, or other areas prone to flooding. If local authorities issue a flood watch, prepare to evacuate: Secure your home; if instructed, turn off utilities at the main switches or valves; fill bathtubs with water in case water becomes contaminated or unavailable. Before filling the tub, sterilize it with a diluted bleach solution. Be especially careful if walking and avoid walking through moving water. Moving water can easily knock you off your feet. Avoid driving into flooded areas. Water may reach the bottom of most passenger vehicles causing loss of control and possible stalling. After a flood: Avoid flood waters, the water may be contaminated by oil, gasoline, or raw sewage. The water may also be electrically charged from downed power lines. Avoid moving water. Be aware of areas where flood waters have receded, the road may have been weakened and may collapse under the weight of a car. Stay away from downed power lines and report them to the power company. Stay away from designated disaster areas unless authorities ask for volunteers. Return home only when authorities indicate it is safe. Be caution when returning, there may be hidden damage, particularly in foundations.
