New York isn't thought of as tornado-prone, but our state has recorded more than 400 twisters since the official record began in 1950. Twelve of them have caused loss of life. New York has averaged about nine tornadoes a year since the mid-1990s, when technological improvements and greater public awareness led to better detection of the storms.

[2] The deadliest tornado listed here claimed the lives of nine elementary school students in Newburgh, Orange County in November 1989. Their deaths are officially attributed to the collapse of a school wall as the tornado struck the school, but many experts argued the collapse was due to a strong downburst, not tornadic winds.
[3] Prior to 1996, the National Weather Service assigned a dollar range when it estimated property damage from a tornado. An entry of “0” means no estimate was provided.
[4] When more than one county is listed, the first is the county where the tornado initially touched down. The others are in order of the tornado’s progression.
