  2. Archived Local Storm Reports Shapefiles

This page allows you to generate a GIS shapefile of NWS issued Local Storm Reports 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 lsrs, you can find with the following files generated every 5 minutes: ESRI Shapefile, Comma Delimited, GeoJSON.

Looking to automate the downloading of LSRs?
You can use the following URI form to get the most recent number of seconds worth of LSRs. Note that these times are based on the valid time of the LSR and not the issuance of the text product itself that contained the LSR.
