Flash Flooding

Flash Flooding ,water Flash Flooding Warning means NOW!

If heavy rain has fallen over a long period of time river flooding can occur and last for weeks or longer.  Some floods are seasonal and with spring rains and melting snows the rivers can fill quickly.  Hurricanes and tropical storms are another source of flooding in the summer and fall. 

Flash floods come when the rain is heavy.  The flash flooding can occur in mountain streams, canyons, or dry washes.  Cities and suburbs can have flash flooding in low spots.  Sometimes with the amount of rainfall the water can not sink into the ground and will rush down stream and fill up banks causing overflow. 

When a flash flooding warning has been issued in your area it means there is flooding now.  Stay away from low lying roads and low spots during the flooding.  Two feet of moving water is enough to sweep a car or truck away, uproot trees, wash out roads and bridges can start to tumble. 


If you are caught in a flash flood, do not drive over or through a flooded bridge or road. Back up and try a higher route. If your vehicle is surrounded by water, get out and seek higher ground. If you are stranded in a tree or building, don't leave it to enter the flood water.


Some of the flood water collects in large, underground reservoirs, but most of it forms rivers and streams that flow into the oceans, bringing the water back to its starting point.  Completely drying out a flood can take anywhere from twelve hours to a few weeks, depending on the size of the flood. 

Floodwaters are contaminated because they carry sewage and other pollutants. This type of contaminated water is commonly referred to as brown or black water. 

Floods are the most common natural disaster in the United States.  You need to have a plan for your household and your pets.  Make sure your family knows what to do, where to go, and what you will need to protect yourselves from flooding. Practice evacuation routes, shelter plans, and flash flood response. Gather supplies, including non-perishable foods, cleaning supplies, and water for several days, in case you must leave immediately or if services are cut off in your area.  Flooding can happen suddenly and being prepared will save time and possibly lives.  Stay weather alert and do not return to hazardous situations until your area has been cleared.
