Ossining, the town this property stands in, in 15 storm reports between 1994 and 2024: 11 thunderstorm wind, 3 flash flood, 1 hail.
The reports record 1 death. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
Flash flooding resulted in an estimated $92.6 million in damages across Westchester County. This estimate includes $78 million in FEMA individual assistance to property owners, renters, and businesses and an additional $14.6 million in damages to Westchester County government infrastructure.
A television camera man reported large diameter trees snapped off. The Journal News showed a tree that fell onto a crushed a truck on Ferris Place in Ossining. Power lines and a transformer were also damaged.
As a line of severe thunderstorms moved southeast, it produced high winds that downed numerous trees and power lines from Ossining northeast to Croton Falls. Local police and newspapers reported numerous trees and power lines downed in Ossining. Several newspapers reported that a large tree toppled over onto a moving car on Route 22 in Croton Falls.
A cold front sweeping across the region generated a line of heavy showers and thunderstorms. Some trees and power lines were downed as strong winds aloft were brought to the surface in the thunderstorms downdraft. Winds gusted between 50 and 60 knots for only a couple of minutes as the outflow generated by the parent storm passed through. Some residents reported that the sky never blackened and there was no thunder or lightning when the actual winds struck.
