Part of the tornado outbreaks of 1989

A destructive series of tornadoes in damage struck the Northeastern United States on Monday July 10, 1989. The storm system affected five states with severe weather, including hail up to 2.5 inches (6.4 cm) across, thunderstorm winds up to 90 mph (140 km/h), and 17 tornadoes. Several towns in New York and Connecticut were particularly hard-hit. Several homes were leveled in Schoharie, New York, and extensive damage occurred in Bantam, Connecticut. A large section of Hamden, Connecticut, including an industrial park and hundreds of homes, was destroyed, and in some places, buildings were flattened to the ground.

The tornado outbreak injured more than 150 people, and straight-line thunderstorm winds killed one person. While tornado outbreaks in this area are unusual, this storm was especially rare in that it produced six significant tornadoes, including two violent F4 tornadoes and several long-tracked tornadoes.
