Known 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 EVENT_YEAR and EVENT_EPISODE_ID for parent-event analysis. Original YEAR, YEARMONTH and EPISODE_ID 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.
TOR_LENGTH, BEGIN_RANGE, END_RANGE and TOR_WIDTH 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.
