County vs. Polygon Latitude/Longitude points at the bottom of all TORs, SVRs, FFWs, and SMWs.
4
Polygon Information in Warnings Today Polygons graphically highlight the area of greatest threat Latitude/longitude vertex points included in all short duration warnings –TOR, SVR, FFW, SMW
5
The Challenge Dissemination –Many TV Stations not prepared to display polygons Niche market for private sector (e.g., WeatherData) –NOAA All-Hazards Radio Technical limitation: location is based only on county New generation of NWR needs to allow users to input either lat/long or nearest city to take advantage of polygon technology
