About Tornadoes in Bloomfield

This overview was written July 29, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.

Bloomfield sits in Hartford County, in the lowlands of the Connecticut River Valley where the terrain climbs west toward Talcott Mountain, and the town's tornado history is longer and harsher than New England's mild reputation suggests.

On October 3, 1979, an F4 tornado tore an 11.3-mile path up to 1,400 yards wide through the area, killing 3 people, injuring 500, and causing $275 million in property damage. Years earlier, on May 24, 1962, an F3 tracked 11.6 miles, killing 1 person and injuring 50. August 21, 1951 brought back-to-back strikes: an F2 that traveled 43.9 miles and injured 9 people, and an F3 the same day that injured 8.

The Enhanced Fujita era has produced its own destructive day. On June 1, 2011, an EF3 traveled 37.58 miles on a path as wide as 880 yards, leaving 3 dead, 200 injured, and $227.6 million in damage. More recent seasons have brought weaker tornadoes: EF1s on May 15, 2018 and September 4, 2019, and EF0s on July 18, 2021 and June 21, 2024.

These dates cluster in the warm months, midsummer above all, but the edges of the season deserve respect here: the F4 of 1979 struck in October, and an EF0 touched down as late as November 13, 2021.
