PRECAUTIONARY/PREPAREDNESS ACTIONS... Most flood deaths occur in automobiles. Never drive your vehicle into areas where water covers the roadway. Flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the road. When encountering flooded roads, make the smart choice: turn around, don`t drown. Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, and ponding of water in urban areas, highways, streets and underpasses as well as other poor drainage areas and low lying spots.
