Aftermath

Because there were no tornado warnings before the storm (and it occurred in an area where tornadoes are rare), the initial damage reports claimed an explosion had damaged a roof. Soon, however, the storm's nature and impact became apparent. Governor Ella Grasso lived just a block away from the tornado's path, though she was in Hartford at the time of the storm. She declared an 8 pm–5 am curfew in the days following the tornado. About 500 National Guardsmen were activated to prevent looting

), or $442 million in 1997 dollars.

Because of the vast scope of the damage, initially Windsor town officials feared many, possibly even hundreds, of people could have been killed. While there were many serious injuries, only three people were killed by the storm. Two victims,construction workers, working in a bank parking, lot took shelter in a work truck when they saw the storm approach, the first victim was killed immediately by a piece of flying lumber, the other died a few weeks later from his injuries becoming the 3rd victim. The second victim was found the next day across the street from her obliterated house. . Over 400 people were hospitalized, mostly for injuries from flying glass or the victims' having been thrown by winds.
