Remnants of Tropical Storm Debby will bring heavy downpours, flood threat on Friday

PITTSBURGH — Off and on rain from the remnants of Tropical Storm Debby will bring heavier downpours and the threat for localized flooding. Plan to use wipers and headlights through at least lunchtime as the system moves through.

A Flood Watch has been posted for the mountains east of the ridges where higher rain totals are expected.

Right now, Pittsburgh and points west including Beaver, Washington and most of Butler counties will see lesser impacts from rain while Westmoreland, Fayette, Armstrong and Indiana can expect slightly higher rainfall totals.

Overall, most areas in Allegheny County will see anywhere from a quarter of an inch to a little over 1 inch of rainfall which should not cause flooding, however, this system is still developing and a shift of as little as 30 miles could dramatically change the rainfall forecast.

The system will move out quickly taking the steadiest rain east by noon Friday, leaving only an isolated shower or storm through the afternoon.

Cooler and much more comfortable weather moves in Friday afternoon and evening setting up a fantastic weekend.
