A heavy thunderstorm dumped rain Thursday on parts of Allegheny County, prompting the National Weather Service to issue a flash flood warning and police to close some streets.
The weather service last night also confirmed an earlier report of a tornado touchdown in Washington County.
A funnel cloud was reported around 4 p.m. in the Eighty Four area where South Strabane, North Strabane and Somerset townships meet. After touchdown, the tornado caused minor damage.
In Allegheny County, the thunderstorm dumped more than an inch of rain on Moon, where the weather service is based, between 2 p.m. and 6 p.m., said Rihaan Gangat, a meteorologist with the National Weather Service.
A trained spotter reported 1.85 inches of rain in Penn Hills and a county official told the weather service flooding was reported in Clarion, Wilkins and Baldwin Borough, where first-responders rescued someone on Streets Run Road.
Flooding prompted police to temporarily restrict traffic to one lane in each direction on Route 51 at Lewis Run Road in Pleasant Hills, an emergency dispatch supervisor said.
Commuters on Friday morning faced areas of drizzle and fog, the weather service said. Highs are expected to reach into the mid 60s under mostly cloudy skies.
