North Texas Graphical Warnings

The graphical severe weather warnings project (GWARN) represents a collaborative effort between the National Weather Service Fort Worth, TX, the National Weather Service Southern Region Headquarters, and the North Central Texas Council of Governments.  Using the warning polygon area, a demographic database at the North Central Texas Council of Governments is queried to determine characteristics of the population at risk.  This has served as a model for numerious other collaborations where demographics have become incorporated into weather impacts and warnings.  Below are current National Weather Service warnings mapped and presented with estimated populations in the impact area.
