A Powerful Storm System To Impact the Southern Plains to the Gulf Coast

A vigorous storm system will develop over the southern Plains and deliver several threats on Thursday. Strong winds are expected across the region along with fire weather concerns from southeast New Mexico to south Texas. A marginal risk of severe storms and excessive rain from the ArkLaTex to the central Gulf Coast. Even a few inches of snow will be possible in Texas, including just west of DFW. Read More >

North Texas Flash Flood Climatology

   

 

Flash flooding kills more people annually than any other type of severe weather.  There are numerous social, educational, and political issues that contribute to the high fatality rates associated with flash flooding.  According to the American Meteorology Society (AMS), flash flooding is a “flood that rises and falls quite rapidly with little or no advance warning, usually as the result of intense rainfall over a relatively small area.”  But what does that mean?  How much rain over how big of an area constitutes a flash flood?  Forecasters, the public, the media, storm spotters, and law enforcement officials all have ideas about whether a situation is a flash flood or not.  It is ultimately up to National Weather Service (NWS) forecasters to classify whether an event is a flash flood.  Storm Data, issued by the National Climatic Data Center, is the official publication for severe weather events.  Flash flooding was first documented in Storm Data in 1995. 

 

Unlike other severe weather events, such as tornadoes and hail, flash flooding can be caused and exacerbated by high population densities and poorly planned urban infrastructure.  This makes flash flooding a unique warning and forecasting challenge as forecasters must take into account more than just meteorological factors.  That is why this database, which identifies the most dangerous locations in north Texas, can be a crucial piece of information for issuing effective warnings.  In addition, findings from this study may be incorporated into warning templates, thereby strengthening the public’s perception of danger and hopefully saving lives.
