  • Federal declarations are administrative actions and do not enumerate every damaging local incident.
  • Statewide-only and tribal designations are intentionally excluded from exact-county counts.

NOAA records by year

Coverage: Jan 1, 1996 – Jun 30, 2026.

No matching county records in this source for the stated coverage period. This is not a claim that no disasters occurred.

Official source: NOAA NCEI Storm Events Database
  • Storm Events reports are not a complete loss inventory and reporting practices vary over time.
  • Forecast-zone and marine-zone records are excluded because they cannot be assigned exactly to one county.
  • 15 optional archive damage cells contained only a K/M/B suffix, so their dollar amounts remain unknown/null rather than inferred.
  • 2 archive record with an unrecognized CZ_TYPE was excluded rather than attributed to a county.
  • The current-year file is preliminary through the latest event present in its selected official revision.
