Middlesex County, Connecticut

County storm and disaster record · FIPS 09007

NOAA's Storm Events Database holds 491 records for Middlesex County, Connecticut from 1950 through June 30, 2026, on 302 days; the most frequent are winter storm records (169 records). 258 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 April 23, 1998 strong wind, filed for the forecast zone Southern Middlesex, which covers the county: 1 death and 1 injury. FEMA has issued 28 declarations naming the county since 1978, 26 of them for natural hazards; the latest for a natural hazard was “Remnants of Hurricane Ida” on October 30, 2021.
