The tornado touched down on the grounds of the Hebrew Home for the Aged along the east bank of the Hudson River west of Palisade Avenue in Riverdale. High winds flattened a flag pole, downed trees and snapped and sheared off many tree tops. A few trees crashed through first floor windows that caused them to shatter resulting in 7 minor injuries. On the south side of the building, large trees were totally stripped of their canopies and one became a projectile as it was wedged between an upstream tree. An eyewitness account at this location stated that he saw funnel clouds develop upstream over the Hudson as the thunderstorm approached.
Several eyewitnesses along the southeast path of this storm stated that they saw clouds and debris swirl in white out conditions as many tree tops were snapped and sheared off. Significant damage occurred along West 254th Street northwest across Netherlands and Arlington Streets, where at least one residential roof was damaged west of 254th Street.
