Flash Flood Warnings
Flash Flood Warnings
Flash Flood Warnings - what are they? A Flash Flood Warning is a short-fuse bulletin issued by the National Weather Service when
a flash flood is present or imminent in the warning area. Flash flood warnings can be issued when the Doppler radar
indicates very heavy reflectivities and hence outflow from thunderstorms, but more often are taken into account along
with the current water content of the soil and other factors. Flash floods are deadly killers - flash flood warnings should
therefore be treated as potentially dangerous as a tornado warning.
When flash flood warnings are issued, they are entered in the AFOS system where they are routed to the central AFOS facility in
Maryland and then disbursed through various channels. One of the quickest ways to get flash flood warnings is through the
StormWarn email delivery service.
