Heavy downpours, localized flooding possible Thursday

PITTSBURGH — Rain from Tropical Storm Debby moves north Thursday bringing the threat of heavy downpours and localized flooding to parts of our area.

Clouds will thicken up after lunch with isolated showers developing before sunset. Steadier rain will fall overnight Thursday into early Friday, with periods of heavy rain and thunderstorms.

Right now, the heaviest rain from Debby is forecast to fall east of Pittsburgh with the highest totals in Westmoreland, Fayette, Armstrong and Indiana counties and central Pennsylvania.

However, a shift of as little as 50 miles could bring higher rainfall totals toward Pittsburgh, so stay weather-aware.

Flood watches have already been issued for some areas with more flood alerts expected as the system gets closer.

As the storm moves out on Saturday, cooler, less humid air moves in.
