About the FEMA and NOAA records
FEMA declarations are federal administrative actions that include a county designation; they are not a complete inventory of every local event.
NOAA Storm Events are county-coded observed-event reports. Forecast-zone and marine-zone reports are excluded from county totals.
FEMA and NOAA records remain in separate counts, comparisons, and coverage periods.
