The National Weather Service files these reports in its Local Storm Reports. A storm collects any two reports that fell no more than 75 miles and 6 hours apart, and any report already linked to either one joins that storm too, even when the reports sit in different states. Storms that last more than 48 hours are divided at the hour where reports are fewest, and each part is checked again. A page needs 5 reports or a top of 2 inches, and at least 3 reports either way.

All states touched

National Weather Service offices file Local Storm Reports; the Iowa Environmental Mesonet of Iowa State University relays them to this page, where they appear as live spotter reports. Under 17 U.S.C. 105, no copyright attaches to the government-produced figures on this page, including reports, alerts, station observations, and normals, which were created by the National Weather Service and other NOAA offices. The notice that 17 U.S.C. 403 requires appears in this sentence. It does not imply endorsement by or affiliation with those agencies. See: Data sources and attribution.
