National Weather Service Issues Flood Warning as Storms Unleash More Rain

More than two inches of rain has fallen in past few hours.

As storms continue to roll through the area, the National Weather Service issued a flood warning for urban areas and small streams Friday night.

The warning covers Allegheny, Beaver, Butler and Westmoreland counties until 2:30 a.m. Saturday.

The National Weather Service also issued a flash flood watch at 9 p.m. Friday that is in effect until 4 a.m. Saturday.

The flash flood watch area encompasses Allegheny, Butler and Beaver counties. A flash flood watch means conditions may develop that lead to dangerous flash flooding.

“Some locations in Western Pennsylvania received between one and four inches of rainfall on Thursday,” the National Weather Service reports. “With additional rainfall expected to move into the region this evening … the possibility exists that flash flooding could develop.”

"At 8:27 p.m. EDT slow-moving thunderstorms across the warning area have dropped over two inches of rain in the past several hours," the weather service website states.

"Additional rainfall is expected through midnight tonight," it said.

"Road flooding can be expected in highly urbanized areas where heavy rain persists," it said. "Residents along streams and creeks should be alert for rising stream levels."

A flood warning means flooding is imminent or has been reported. Additional heavy rain might cause flash flooding.

"Most flood deaths occur in automobiles. Never drive your vehicle into areas where the water covers the roadway," the National Weather Service warns. "Flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the road."

If you see flooding in your area, please let us know by posting in the comments.

A couple of houses in the 3800 block of Route 910/ Gibsonia Road in Richland Township have requested assistance from fire department for basement flooding. That area is close to the railroad tracks—an area that has flooded previously. Area is near Hardt Road and Gibson Road.

Also hearing reports of flooding near Kress Tires on Route 910 in West Deer Township, not far from Richland Township line.

Another problem with a flooded basement in Richland Township. This time it is on Grandview Drive, not far from Route 8.

Earlier this evening, I heard a lot of calls for Hampton Township—tree down on Harts Run Road and flooding in a home south of there.

Just heard Route 910 in West Deer is open again, water has receded. Also heard Harts Run Road is clear and open.

Police are requesting fire company and PennDOT to come to intersection of Route 910 and Dickey Road in Richland Township - road starting to buckle? Water main break?

Would like to have the creek checked, that runs along English Road. It is flooding up into our yard, and it hasn't done that since we moved in a year ago. Is there a water main break?

Philip and Kristen, Just saw your comments this morning; not sure why they did not publish last night. Are you still having problems this morning? I was tracking some stuff on our Facebook page last night. Seems the Route 910 area around the railroad tracks had the most problems.

Excellent reporting! I looked for news of the storm on the websites of large local papers, and they are still reporting Thursday's storm. They should take a lesson from you on timely, detailed reporting.

Thanks, Laura! I'll be out this morning as a followup. If anyone has anything storm-related going on in their neighborhood, please call me at 724-799-9982. I started driving around last night, but decided it was getting dangerous out there and came home.

old news, but new to me, 910 at Dickie Rd is reduced to single lane with a stop sign installed. This looks semi permanent with warning signs posted on poles that are pounded in the ground (rather than the kind with sand bags on them). Probably until they can check out the buckle that the water made in the road. (Road looks fine now but I suppose under the surface there is damage)
