...Severe Weather Awareness Week...


Flash flooding refers to a dangerous sudden rise in water along a
creek, river, or a normal dry land area. Flash floods result from
heavy rainfall, sudden breaks in river ice jams, and dam or levee

Flash floods can occur within a few minutes or hours, and can move
at surprisingly high speeds, striking with little warning. Flash
floods are quite destructive because of the force of the moving
water, and the debris that accumulates in flood waters, such as
trees and boulders, which can destroy roadways, bridges, and

Other complications in Colorado are recent wildfires which raise the
flood threat when locally heavy rain falls on recent burn scars.
Residents in and near burned areas should plan ahead on response
actions for flooding. Nearly half of all flash flood fatalities are
vehicle related.

Do not enter a flooded roadway, instead Turn Around, Don`t Drown.

In rapidly rising waters, backing up away from water may be safer.
One or two feet of water will carry away most vehicles, and you also
cannot tell if the road is damaged beneath moving water.

Colorado Severe Weather Awareness Weekcontinues through this
Saturday.Remember, Turn Around, Don`t Drown!
