SPC Severe Weather Database

Open SPC historical severe-report database compiled from NWS Storm Data, currently covering U.S. tornadoes 1950–2025 and hail/damaging wind 1955–2025. Annual/full-period CSVs and SVRGIS path/initial-point shapefiles are one product family. Tornado files include raw state/county segments and de-segmented actual tracks. Magnitude means F/EF rating for tornado, inches for hail, and knots for wind with measured/estimated gust/sustained qualifier. Dated releases can correct and reprocess records, so retain release metadata. It is not a complete census, radar footprint, or building-impact dataset. SVRGIS creates a 0.0001-degree offset endpoint when no real endpoint was reported.
