Pittsburgh, Pa. – Torrential thunderstorms on Tuesday night have led to flash flooding in parts of Western Pennsylvania, affecting several counties from Fayette to Clarion. The heavy rainfall has caused small creeks to overflow, stranding drivers and creating hazardous conditions.
Flash Flood Warnings Across Multiple Counties
The National Weather Service in Pittsburgh has issued flash flood warnings for several counties, including Indiana, Westmoreland, Armstrong, and Jefferson, which will remain in effect through at least 10:30 p.m. Radar data and law enforcement reports confirm that 1 to 2 inches of rain have fallen in under an hour, with more rain expected throughout the evening.
Affected Areas and Rising Waters
In southeastern Westmoreland County, towns like Latrobe, Mount Pleasant, and Ligonier are reporting street flooding and rising water levels in underpasses. Meanwhile, Oil City officials confirmed flash flooding had already started by 7:30 p.m., as storms moved east at a rate of 15 mph. Nearby towns such as Franklin, Sandy Lake, and Sugarcreek are also experiencing flooding.
Northern Fayette and southern Westmoreland counties are not spared, with flash floods affecting towns like Connellsville, California, and Seven Springs. Some areas have seen rainfall rates as high as 1.5 inches per hour, increasing the risk of flooding.

Residents in the affected areas are advised to avoid all unnecessary travel, especially after dark.
