The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A tornado briefly touched down in a few locations. The first report of a touchdown was in Woodmere where several trees and powerlines were down. From there, the tornado lifted and skipped in a few locations as it traveled nearly 50 mph to the northeast towards Hempstead, Uniondale, and Levittown. Here, damage reports were sporadic, but in Uniondale NY, the tornado touched down again and tore a roof off a two-story colonial building on Liberty Street, which landed on a nearby house. Scattered debris, including shingles, insulation and twisted siding was thrown into the next block up, including the intersection of Emerson and Goodrich Street. Significant damage was also noted near Clover Lane in Levittown, where a large tree was felled onto a house before the tornado lifted.

The wider storm

A strong and slow moving frontal boundary, along with a potent mid level disturbance triggered strong to severe thunderstorms which impacted Southeastern New York. Six tornadoes also touched down across Long Island with one in Nassau County and five across Suffolk County.

Began near Hewlett (40.6249, -73.7198).
