Rounds of heavy showers and thunderstorms caused destructive flash flooding around Pittsburgh on Wednesday evening.

A state of emergency was declared in the towns of Bethel Park and Upper St. Clair, CBS Pittsburgh reported. Both communities are located about 30 minutes south of Pittsburgh.

At least 66 water rescues were reported in Allegheny County, an official told the news station. Numerous vehicles were stranded due to impassable conditions in the county.

Nearly 4 inches of rain fell in Monroeville, while around 3.40 inches fell in Washington, Pennsylvania. Road closures were reported around the town of Bridgeport, where about 3.3 inches had fallen.

“Until flooding conditions subside, DO NOT drive on the roadways. Seek shelter on upper floors or higher elevation,” the Bethel Park Police Department said on Twitter.

The Pittsburgh Port Authority reported its Blue Line light rail service was suspended due to flooding and storm damage on the tracks.

The heavy rain also forced the Major League Baseball game between the Milwaukee Brewers and Pittsburgh Pirates to be postponed.

Although dry weather aided cleanup and recovery efforts on Thursday, a storm system will bring rainfall back to the region starting on Friday and lasting into the weekend, according to AccuWeather Long-Range Meteorologist Evan Duffey.

"Between Friday afternoon and Sunday afternoon, multiple rounds of showers and some thunderstorms can be expected," Duffey said. "While rainfall does not appear to be as heavy as the rain that lead to the flooding in southwestern Pennsylvania, it will aggravate any flooding issues and continue to swell area rivers and streams."
