About Tornadoes in Franklin Square

This overview was written April 23, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.

Franklin Square, New York, sits within a 25-mile radius that has recorded 31 tornadoes since 1950, according to the NOAA Storm Prediction Center. While tornadoes are often associated with the Great Plains, this Long Island community and its surrounding area experience periodic tornado activity, with events documented across seven decades. The majority of these tornadoes have been relatively weak, with 11 rated EF0 and 15 rated EF1 on the Enhanced Fujita scale, which measures tornado intensity from EF0 (weakest) to EF5 (strongest). Five tornadoes reached EF2 intensity, capable of causing considerable damage to structures.

Tornado activity in the Franklin Square area peaked during the 1970s, when 11 tornadoes were recorded within the 25-mile search radius. Activity declined sharply in the 1980s with only 3 events, then fluctuated through subsequent decades: 5 tornadoes in the 1990s, 4 in the 2000s, and 7 in the 2010s. The current decade has seen 1 tornado as of the data collection date. Unlike many regions where tornado season peaks in spring, the Franklin Square area sees its highest activity in August, which accounts for 10 of the 31 recorded events.

The most significant tornado in the area's modern record occurred on September 16, 2010, when an EF1 tornado caused one fatality and $17.2 million in property damage. This event, which carved a 4.0-mile path with a maximum width of 100 yards, stands as both the deadliest and costliest tornado on record for the region. The widest tornado documented was an F1 that touched down on July 19, 1971, reaching 400 yards in width during its 2.0-mile track and causing $275,000 in damage.

The most recent tornado struck on November 13, 2021, an EF0 event that traveled an exceptional 13.1 miles—the longest path length recorded in the area—while maintaining a relatively narrow 50-yard width. This tornado caused $300,000 in property damage but resulted in no fatalities, consistent with the generally lower-intensity tornadoes that characterize the region's historical pattern.
