Pittsburgh, PA – Heavy rainfall sweeping through southeastern Pennsylvania and northern West Virginia could lead to flash flooding this afternoon as a slow-moving front crawls south.
According to the National Weather Service in Pittsburgh, a Level 1 (Marginal) risk of flash flooding is in effect through early evening Tuesday, with the greatest concern in southeastern Pennsylvania, northern West Virginia, and along the Appalachian ridge. This zone faces at least a 5% chance of excessive rainfall leading to flash flooding within 25 miles of a given point.
The heaviest rain is expected midday through late afternoon, potentially impacting cities such as Morgantown, Uniontown, and Johnstown. Drivers on I-68 and Route 219 should watch for ponding and reduced visibility, especially in low-lying or poorly drained areas.
Residents are urged to monitor NOAA Weather Radio or local alerts and ensure mobile devices are set to receive emergency warnings. Those in flood-prone neighborhoods should prepare to move vehicles to higher ground and avoid walking or driving through flooded roadways.
The flash flood risk may shift or expand later this week depending on the front’s movement. Additional alerts could be issued if rainfall rates intensify.
