Flooding can occur as streams and rivers flow over 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.
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 necessary.
Do not drive through flooded areas. If you see a flooded-out roadway ahead, turn around and find another route to get to your destination.
If there is no other route, proceed to higher ground and wait for the waters to subside.
Even if the water appears shallow enough to cross, do not attempt to cross a flooded road. Water can conceal dips, or worse, floodwaters can damage roadways, washing away the entire road surface and a significant amount of ground.
If your car stalls, abandon it immediately and climb to higher ground.
Remember, 6 inches of water will reach the bottom of most passenger cars, causing loss of control or possible stalling.
One foot of water will float many vehicles.
Two feet of rushing water can carry away most vehicles including SUV's and pick-ups.
