It is possible to experience a flash flood in areas not immediately receiving rain.
What’s the difference between a flash flood watch and a flash flood warning?
A flash flood warning is issued when a flood is imminent or occurring, the NWS says. If you are in a flood prone area, you should move immediately to high ground. The NWS issues a flash flood watch when flash flooding is possible.
What to do during a flood warning
If advised to evacuate, do so immediately.
Use a battery-operated radio or television to get the latest emergency information.
Do not walk through floodwater. Just six inches of floodwater can sweep you off your feet if it is moving swiftly.
Turn around, don’t drown; do not drive into a flooded street. Cars can be swept away by two feet of moving water or there may be unseen damage to the road. If you come to a flooded area turn around and go another way. Most flood-related deaths are caused by people driving through water.
Watch out for fire hazards.
Stay alert, turn weather notifications on.
Do not allow children to play in flowing water. Waters can hide rocks, trees and debris.
