Flood Hazard:
A flood can occur when tropical storms, hurricanes or other heavy rainstorms are apparent. The flood hazard areas in the Palm Beach County are: along the coastal ride, Hagan and Clair Ranch tracts, Loxahatchee Wildlife Preserve, J W Corbitt Preserve, surrounding Lake Okeechobee, and inland bodies of water.
Flood Warning Systems:
Palm Beach County depends on the National Weather Service (NWS) for flood recognition. The NWS will issue a flood advisory for Palm Beach County at least six hours before expected rainfall would overflow drainage systems and cause the isolation of structures by the inland ponding of flood waters. Stay tuned to local TV or radio stations known to have an active new bureau. When flood warnings are issued, it will be done first through the Emergency Alert System, then if needed, by sirens and loudspeakers form police and fire vehicles that will give evacuation routes.
