How to interpret this hazard lens

Hazard categories normalize source labels into a shared taxonomy; source definitions and reporting practices still differ.
FEMA declarations reflect federal administrative actions and do not inventory every damaging local event.
NOAA totals include only distinct county-coded Storm Events records; forecast-zone and marine-zone records are excluded.
Only counties with a positive count for this category appear in each source table. Open a county profile for its complete source disclosures and preparedness context.
