Power is returning to customers of Duquesne Light and West Penn Power following a series of storms that moved through Western Pennsylvania on Sunday evening.
The National Weather Service’s Pittsburgh office in Moon issued severe thunderstorm warnings and tornado watches and warnings throughout the day Sunday. The weather service said the threat of severe weather ended around 9 p.m.
As of 10 p.m. Sunday, more than 10,000 Duquesne Light customers — in Allegheny and Beaver counties — and over 14,600 West Penn Power customers — in Allegheny, Washington, Westmoreland, Butler, Armstrong and Beaver counties — were without power.
By 8:30 a.m. Monday, those numbers dwindled down to just shy of 5,000 in total.
About 2,000 Duquesne Light customers — about 1,760 from Allegheny and nearly 270 from Beaver — were without power. Nearly 2,700 West Penn Power customers were without power as of 8:30 a.m. — nearly 350 in Allegheny, 850 in Armstrong, 140 in Beaver, 680 in Butler, 545 in Washington and 110 in Westmoreland.
Duquesne Light estimates power will be restored by 4 p.m. Monday, according to a message posted on its website.
“There are still many hazards around the area, including downed wires, poles and trees,” the message reads. “We strongly encourage you to exercise caution and maintain at least 30 feet of distance from downed power lines.”
National Weather Service staff will conduct storm surveys Monday where tornado warnings were issued and damage reports were received yesterday.
Crews will particularly investigate Jefferson County and Ohio’s Columbia County, where the weather service is most confident tornadoes passed through Sunday, said Meteorologist Chris Leonardi. A survey team also could be sent Tuesday to Butler County, he said.
Scattered wind damage, including downed power lines and trees, has been reported across Western Pa., Leonardi said.
9PM: The severe threat has ended and will give way to a cool overnight with lows in the 50s and a few lingering showers. We will be conducting storm surveys tomorrow where the tornado warnings were issued and we received damage reports. More information will come tomorrow morning pic.twitter.com/iG7SoqAFOI

The weather service Sunday issued a tornado watch for eight Pennsylvania counties — including Allegheny, Armstrong, Butler, Indiana and Westmoreland. A tornado warning was issued for the southeastern portion of Allegheny County and west central Westmoreland County.
No further storms are forecast until mid-week, Leonardi said.
“We have a pretty potent system, especially for June, that’s going to be crossing Thursday,” he said, noting some storms could begin rolling through Western Pa. on Wednesday evening.
As the week progresses, the weather service will have a better idea of whether to expect tornadoes Thursday, Leonardi said.
