The National Weather Service and its Office of Meteorology and Office of Hydrology have produced many brochures and videos detailing the hazards of floods and flash floods. Among the videos are, "The Awesome Power" and "The Hidden Danger, Low Water Crossings." You can view either of these movies by clicking here. You will need RealPlayerto view the videos. Don't have the software? Don't worry. You can download your RealPlayer at the same site.

Some of the statistics are in a .pdf format.

Interested in how floods/flash floods have compared to other weather-related disasters during the past several years?

Floods and flash floods often occur in concert with the approach and passage of tropical weather systems, like hurricanes. When tropical weather systems threaten any area common to the Southern Region Headquarter's area of responsibility, the Southern Region Regional Operations Center is opened and staffed around the clock until the threat passes. The latest tropical information and forecasts can be found at NWS Southern Region Headquarters.

Warning Coordination Meteorologists (WCMs) implement the hazardous weather warning, preparedness, and coordination programs for their office's County Warning Areas (CWAs). This includes flood and flash flood safety and awareness. They also engage in projects with agencies outside the NWS and serve as public education and customer service points of contact within their CWA. The names of the 31 Southern Region WCMs, as well as can be found here.
