Search for NWS Watch/Warning/Advisories Products by County/Zone
The National Weather Service issues watch, warnings, and advisories (WWA) for counties/parishes. For some products (like winter warnings), they issue for forecast zones. In many parts of the country, these zones are exactly the same as the counties/parishes. When you get into regions with topography, then zones will start to differ to the local counties.
This application allows you to search the IEM's archive of NWS WWA products. Our archive is not complete, but there are no known holes since 12 November 2005. This archive is of those products that contain VTEC codes, which are nearly all WWAs that the NWS issues for.
Please note: NWS forecast offices have changed over the years, this application may incorrectly label old warnings as coming from an office that did not exist at the time.
The table will automatically populate below once you make your selections above. Click on the linked Event ID to get more information on the warning.
