Flooding
Because of its vast network of rivers, creeks, streams, and its the proximity to the Chesapeake Bay, the State is considered to be flood prone. Flooding may be caused by heavy rains, fast snow melts, or dam failures.  When this occurs, the natural waterways can become raging torrents capable of great destruction.

Warning
Except in the case of flash flooding, the onset of most floods is a relatively slow process with the buildup taking several days. Progressive situation reports are available from the NWS and the River Forecast Center district office of NOAA. Check with your emergency operations center because different areas are served by different agencies (NOAA/NWS and River Forecast Centers)
Flash flood watches are issued by the NWS to the public by radio/TV stations. A watch means that flooding MAY occur.
Flash flood warnings are issued by the NWS to the public by radio/TV stations when flooding is actually occurring.

Preparation
Know what a forecast river height means as it relates to the facility. Helpful information includes:
  Know whether or not the facility is in a flood plain.
  Knowledge of how elevations relate to river gauges from which a forecast is prepared.
Response
Evacuate children to shelters
Shut off water at mains so contaminated water will not back up into facility supplies.
