Thunderstorms

A thunderstorm is a storm that contains both thunder and lightning. These storms can produce flash flooding, gusty winds, hail, and even tornadoes. The southern part of the United States has the highest number of average annual thunderstorms, especially those states located near the Gulf of Mexico and the Atlantic Ocean.

New York typically sees between 20 and 40 thunderstorms a year, depending on the location within the state. Most of the thunderstorm activity is observed during the summer months.
