Flooding can occur as streams and rivers overflow their banks, when dams or levees break, with run-off from deep snow cover, or any time there is rainfall with significant duration and intensity.
Keep these facts in mind to stay alive and dry.
Flash floods can come rapidly and unexpectedly. They can occur within a few minutes or hours of excessive rainfall, or when a dam or levee fails and even a sudden release of water held by an ice or debris jam. Be cautious during storm seasons, or any time that flooding is common in your area.
You may not have warning that a flash flood is approaching.
Do not drive unless absolutely necessary.
If Driving, DO NOT DRIVE THROUGH FLOODED AREAS! Even if it looks shallow enough to cross. The majority of deaths due to flooding are due to people driving through flooded areas. Water only one foot deep and displace 1500 pounds! Two feet of water can easily carry most vehicles. Roadways concealed by floodwaters may not be intact.
If there is no other route, get to higher ground and wait for the waters to subside.
Even if the water appears shallow enough to cross, don't try it. Water hides dips in the road. Worse yet, there may be no road at all under the water. Flooding can scour away the entire road surface and a significant amount of ground beneath.
If your car stalls, abandon it immediately and climb to higher ground.
Six inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.
One foot of water will float almost many vehicles.
Two feet of rushing water can sweep away most vehicles — including SUVs and pick-ups.
If caught outside, go to higher ground immediately! Avoid small rivers or streams, low spots, culverts, or ravines. Do not try to walk through flowing water more than ankle deep, as it only takes six inches of water to knock you off your feet. Do not allow children to play around streams, drainage ditches, or viaducts, storm drains, or other flooded areas.
If ordered to evacuate or if rising water is threatening, leave immediately and get to higher ground.
