NOAA Storm Events 1950–2024
One-time dated snapshot.
Rebuilt storm-event snapshot with event-linked locations and fatalities, source provenance, and separate audit tables.
Verified coverage: Events: 1950–2024; locations: 1972, 1996–2024.
Records: 1,940,615 events; linked locations and fatalities.
This repository contains a 1,000-row public sample, not the full package. A sample does not establish complete historical coverage.
Limitations
- Join locations and fatalities to details by EVENT_ID, which is unique in the event table. Aggregate each child table separately before combining to avoid multiplying rows.
- Use derived EVENTYEAR and EVENTEPISODEID for parent-event analysis. Original YEAR, YEARMONTH and EPISODEID values are retained: 92,268 primary location rows disagree on source year and 2,298 on source episode ID. These source inconsistencies are explicitly flagged, not overwritten.
- The locations audit table retains 282,461 excluded rows: 20,817 linked to 2025 events outside this snapshot, 261,643 with missing coordinates, and one with invalid coordinates. Audit rows are not part of the primary location table; 2025 event details are not delivered.
- Primary location coverage is sparse: two rows link to 1972 events, with other rows in 1996–2024. Complete latitude/longitude pairs pass numeric bounds checks, which do not establish geographic accuracy. Detail-table endpoint coordinates remain as supplied, with missing, incomplete or invalid values flagged.
- TORLENGTH, BEGINRANGE, ENDRANGE and TORWIDTH preserve source decimals. NOAA documents tornado width in whole yards, but 148 source values are fractional; these values are retained without assuming a corrected unit.
- Event types and reporting practices vary over the historical period. The archive is not a complete or uniform history of all weather hazards; long-term comparisons need source-specific qualification.
- Damage amounts are parsed nominal USD estimates, not inflation-adjusted losses. Derived damage, injury and death totals treat missing components as zero; a zero total does not prove no loss or harm.
- This is a dated 1950–2024 event snapshot rebuilt from pinned source revisions. Future updates are not included.
Package upload: 2026-09-19. Listing reviewed: 2026-09-19. These dates do not extend source coverage. Rebuilt from NOAA source revisions pinned September 19, 2026; primary event coverage remains 1950–2024.
