A coastal storm brought a prolonged period of moderate rainfall across portions of eastern New York, mainly on Tuesday, October 26, 2021. While the rain was not falling particularly heavily, persistent rainfall rates of 0.25 to 0.50 of an inch an hour occurred for several hours across portions of Ulster, Greene, Schoharie and Schenectady counties. This resulted in rainfall amounts of 2 to 5 inches across the region. Minor flooding began as early as the late morning hours on October 26, but the greatest coverage of flooding occurred during the afternoon and evening hours as roads began to close. Rivers, creeks and streams also began overflowing their banks leading to additional flooding. Rain ended during the overnight hours, slowly allowing waters to recede. However, roads damaged by the flooding remained closed into the daytime hours of October 27.
Gusty winds between 30 and 40 mph also accompanied the storm which resulted in a few downed trees and some power outages.
New York Governor Kathy Hochul declared a State of Emergency for selected counties across New York State including Greene, Montgomery, Schenectady, Schoharie and Ulster.
