Storm Based Warnings Officially Began October 1, 2007

On October 1, 2007 the National Weather Service will implement Storm Based Warnings nation wide.  The Indianapolis National Weather Service office has been a test site for this concept for the past 3 severe weather seasons. 

Storm-Based Warnings (threat-based polygon warnings), are essential to effectively warn for severe weather. Storm-Based Warnings show the specific meteorological or hydrological threat area and are not restricted to geopolitical boundaries. By focusing on the true threat area, warning polygons will improve NWS warning accuracy and quality. Storm-Based Warnings will promote improved graphical warning displays, and in partnership with the private sector, support a wider warning distribution through cell phone alerts, pagers, web-enabled Personal Data Assistants (PDA), etc.
