Gloucester County, New Jersey

County storm and disaster record · FIPS 34015 · population 302,128 · 322 sq mi

NOAA's Storm Events Database holds 1,217 records for Gloucester County, New Jersey from 1950 through June 30, 2026, on 877 days; the most frequent are severe thunderstorm wind events (313 records). 658 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. The deadliest single record is the March 16, 2007 winter weather, filed for the forecast zone Gloucester, which covers the county: 4 deaths and 14 injuries. FEMA has issued 28 declarations naming the county since 1965, 25 of them for natural hazards; the latest for a natural hazard was “Remnants of Hurricane Ida” on September 5, 2021.
