This application presents a browsable archive of SPC issued tornado and severe thunderstorm watches. Each sequential watch is assigned a numeric ID, which uniquely identifies a watch for each year. Up until 2006, the polygon was the valid area of the watch. Since then, the valid area is issued by county and marine zone.
