Overview

An upper-level disturbance interacted with a very moist atmosphere on July 1, generating widespread thunderstorms across areas mainly along and north of I- 90. These storms resulted in torrential rainfall and flash flooding in portions of Herkimer, Fulton, Warren, Washington, and Rensselaer Counties. It was the second straight day of heavy rainfall for some of these areas. The village of Hoosick Falls was particularly hard-hit by flash flooding, with several residences experiencing basement and first-floor flooding and several roads washed out. Rainfall amounts up to 5" were recorded in Washington County. Several area rivers reached minor and moderate flood stage. A microburst in Sandgate, VT snapped and uprooted many trees with peak winds estimated around 100 mph. A few other reports of wind damage occurred as well.
