An upper-level disturbance interacted with a very moist atmosphere on July 1, generating several rounds of 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 hit particularly hard by flash flooding, with many residences experiencing basement and first-floor flooding and several roads washed out as Woods Brook overwhelmed its flood protection system and coursed through the town. A state of emergency was declared for the village, where an estimated $300,000 in damage occurred. Across Rensselaer County, flooding resulted in an estimated $3.6 million in damage. Rainfall amounts up to 4 were recorded in Washington County where several roads were washed out. Neighboring Warren County estimated $1 million in flood damage. In Herkimer County, a mudslide closed a state highway, and people had to be evacuated from locations in the villages of Herkimer and Frankfort due to rising water. Several area rivers reached minor and moderate flood stage, including the Mettawee River at Granville which crested just below major flood stage.  Finally, a few of the storms resulted in isolated wind damage.

A nearby rain gauge reported 1.63 inches of rain in an hour, and an additional 1.23 inches in the next two hours.

Numerous houses reported basement flooding, with a few reporting flooding on the first floor, leading to evacuations. Three sinkholes developed, one the size of two tractor trailers. Several roads remained closed well into the following day, and flood waters washed out a portion of the train tracks that pass through the village. A local state of emergency was declared.
