Archived NWS Watch/Warnings

This page allows you to generate a custom GIS shapefile (with additional CSV file of events) or Google Earth KML of NWS issued watches and warnings for a time period of your choice. Please be sure to read the archive status and dbf schema below. The IEM's archive is certainly not complete or official. If you are looking for a real-time source of warning shapefiles, you can find that here.

Due to transient server load or other issues, this application sometimes fails to generate output. You may wish to try shorting the duration of your request or email us for help.
