What happened

The episode as NWS ALY wrote it up.

A cold front triggered severe thunderstorms and flash flooding across Dutchess and Ulster Counties. Severe thunderstorms downed trees and wires across several locations in both these counties. Approximately 2,000 customers were without power for several hours. A thunderstorm blew a tree down on a house at Gardiner in Ulster County. Severe thunderstorms also contained large hail. Torrential rains from the storms produced flash flooding across Ulster and Southern Dutchess Counties. In Dutchess County in the Village of Wappingers Falls several basements had to be pumped out. Flooding of roadways occurred at New Preston, Hopewell Junction and Wingdale. In Ulster County, roads were flooded in Rosendale, New Paltz, Shawangunk, Marlboro and Ellenville. At Glasco, in northern Ulster country, four residents of an apartment building were evacuated due to a flooded stream that washed out part of the foundation.
