Thunderstorms that moved through Allegheny County last night brought flooding, hail and high winds.
Flooding is "all over the place," an Allegheny County emergency dispatcher said. Most is in southern Allegheny County, with some in more eastern areas, he said.
With as much as 2 inches of rain anticipated by 9 p.m., the National Weather Service issued a flash flood warning for Allegheny, Beaver, Washington and Westmoreland counties until 11:15 p.m.
The service noted that "urban flooding is likely, especially along Saw Mill Run."
Hail measuring 1 inch was reported in Moon, and Pittsburgh International Airport clocked 44 mph winds, a weather service meteorologist said.
The thunderstorm watch was lifted.
A hazardous weather outlook for Greene, Fayette and Westmoreland indicates damaging winds and hail could continue to be a threat through Wednesday morning.
