Where the numbers come from

2026 figures come from NOAA Storm Prediction Center preliminary reports, verified per event and published on this site within days of each storm. Ten-year figures come from the NOAA NCEI Storm Events Database, finalized records for 2016-2025. NCEI finalizes a year roughly three months after it ends, so the two sets are not identical in method: the preliminary set can include reports NCEI later drops, and NCEI can carry reports that SPC's filtered files leave out. Hail days count verified reports of 1.00 in or larger; a day with several reports counts once. This page rebuilds every time a new report publishes.
