What the reports say
Written by National Weather Service staff at the time of the event · public domain
The remnants of a tropical system combined with a stalled frontal boundary acted to ignite slow moving thunderstorms on the evening of August 30th. These thunderstorms moved over Western Orange County NY for several hours. Hourly radar rainfall estimates in the 3-5" range were observed at times. The hardest hit areas were Port Jervis and Deer Park, where flooding was severe enough to initiate states of emergencies. Houses were damaged, roads were destroyed, and buildings collapsed throughout Western Orange County. Damage estimates were 2.2 million in public and 1.8 million in private property.
In New Hampton, I-84 was closed at Dolson Ave. due to flooding. Additionally, a portion of Dolson Ave. was closed due to flooding, including the intersection of Dolsontown Rd. and Dolson Avenue. Basement flooding was also reported in Middletown.
Heavy rain resulted in ponding of water 1 1/2 to 2 1/2 ft. high in the streets of the 4th ward of Port Jervis, which caused basement flooding in several homes. The department of public works reported 3.25 inches of rainfall in an hour.
