BOLIVAR – Torrential downpours may have dropped as much as 3 inches of rain on portions of southeastern Cattaraugus and Allegany counties in just a 90-minute period Thursday evening, spurring flash flood warnings from the National Weather Service.
“It was heavy and concentrated [in the Portville and Bolivar communities],” said Kirk Apffel, a Weather Service meteorologist in Buffalo. “It’s coming down real hard.”
The heavy rain, associated with the boundary of an advancing upper-level low-pressure system, started in the area about 6:30 p.m. Radar estimates showed as much as 3 inches of rain already fell in the area by 8 p.m.
Local storm reports by the weather service indicate that nearly 1-inch sized hail fell at about 7:35 p.m. in Bolivar. There also was flooding on several roads reported around town as well as trees down from high winds associated with the storm.
Weather Service reports also showed that Lilli Bridge Road in Portville, Cattaraugus County, was overrun with water as the result of the flash flooding.
Allegany County sheriff’s deputies reported no significant damage or injuries with the storm as of 8:30 p.m., but they said there were residents without power.
National Grid estimates showed 98 customers in Allegany County were dark, mostly in the Town of Cuba.
The weather service reported that additional storms were approaching the affected area in Cattaraugus and Allegany counties from the southwest and additional heavy rainfall was expected later Thursday evening.
