Documentation for /cgi-bin/request/gis/spc_watch.py
The IEM archives the Storm Prediction Center (SPC) watch polygons and associated metadata. Please note that these polygons are no longer the official watch geography with watch-by-county being the official product. These polygons are still generally useful and somewhat accurate to the actual watch geographic extent.
