St. Croix Island, U.S. Virgin Islands
Island storm and disaster record · FIPS 78010 · population 40,913
NOAA's Storm Events Database holds 170 records for St. Croix Island, U.S. Virgin Islands from 1950 through June 30, 2026, on 134 days; the most frequent are floods and flash floods (56 records). 99 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day.

FEMA has issued 29 declarations naming the county since 1974, 25 of them for natural hazards; the latest for a natural hazard was “Tropical Storm Ernesto” on October 25, 2024.
