Flash flooding has been reported across the Pittsburgh area on Friday.

Amid the Friday rush hour, heavy rains have led to flooding in multiple communities in Allegheny County, including Monroeville and Rankin. Parts of Westmoreland County, including Greensburg and Jeannette, are also impacted by the storms.

KDKA First Alert Meteorologist Ray Petelin said about 3 inches of rain fell across the two counties over 90 minutes. 

The weather has also led to a rain delay for the Pirates' game against the Phillies at PNC Park in Pittsburgh.  

A vehicle was nearly completely submerged in water on the Tri-Boro Expressway in Monroville after flooding from heavy rain covered the road in rising water. Police responded to the scene. 

In Turtle Creek, The Wolvarena was partially flooded after torrential rains hit the area. 

The National Weather Service also said on social media that there were "multiple reports" of flooded roads and vehicles being stranded in floodwaters near Pitcairn.

Valley Avenue in Wall Borough is covered in debris after flash flooding rolled through the community.

The severe weather created a sinkhole on Valley Avenue in the borough, and residents said they have never seen water levels like that before. Authorities said there were no reported injuries.
