Flood Safety Rules
*During periods of heavy rain, move to higher ground and stay away from low lying areas such as streambeds, drainage ditches, and culverts.
Water runs off streets and parking lots very rapidly causing natural and man-made drainage systems to overflow with rushing flood waters.
These flood waters carry debris that can be deadly to someone in their path. A rapidly flowing stream or ditch can sweep you off your feet or even sweep your car downstream.
* Stay out of flooded areas.
In flooded areas, the water may still be rising and is usually swift. Children are especially vulnerable and should not be allowed to play or walk in flowing water.
* Never drive your car into water of unknown depths or around barricades
Most flash flood deaths occur when people drive their vehicles into flood waters. Flood waters may rise very quickly and could cover the vehicle or sweep it away. If your vehicle stalls, abandon it and immediately seek higher ground.
* Be especially cautious at night, when it is harder to recognize flood dangers.
