NWS Local Storm Reports

The Storm Reports page is organized based on reports received from 1200 UTC to 1159 UTC the next day. For example, storm report page for 20150430 covers reports from 20150430 at 1200 UTC to 20150501 at 1159 UTC.

Note: To access REST service for Local Storm Reports, visit: https://mapservices.weather.noaa.gov/vector/rest/services/obs/nws_local_storm_reports/MapServer/.

Note: On March 8, 2011, the proximity space/time rule is no longer being utilized to de-duplicate events and minimal filtering is now applied to the decoded reports. All comments/remarks in the LSRs are captured on the raw files and the users can decide, for their own purposes, the best way to remove duplicate reports from the LSR's.

Note: Starting January 5, 2010, the daily storm report summaries, below, will record 1 inch and greater diameter hail, as well as severe thunderstorm wind and tornado reports. Please see this link for more information.

Note: These reports are preliminary and are plotted and listed "as is" from NWS Local Storm Reports usually sent in realtime. The SPC does NOT decode non-thunderstorm related LSRs such as hurricane related wind reports. Please see SPC FAQ for more details. Consult NOAA/NWS Storm Data for post-storm summaries and statistics. To obtain official documentation of severe weather, please contact the National Centers for Environmental Information (NCEI). Click here to search the NCEI Storm Events database.
Another good source of Local Storm Reports is Iowa Environmental Mesonet/Iowa State University Department of Agronomy.
