6:30 p.m. update: Close to 300 residents are without power, according to a Met-Ed outage report.

Glen Rock has about 100 outages reported. About 40 outages are reported for the Red Lion area and 20 for each of the Chanceford Township, Hallam Borough and Dallastown areas. The Hanover area has more than 100 outages reported.

Power is expected to be restored by midnight, according to Met-Ed.

A severe spring storm ripped through the region Thursday morning, leaving damage, flooding and downed trees and power lines in its wake.

More than 300 York County residents were without power as of 2:30 p.m., and Met-Ed reported outages could also be high in the afternoon when a second wave of storms are expected pound the region.

Dallastown had the most lights out around noon, with 95 outages reported. Springettsbury Township had 79 outages and York City had 47 outages.

More storms are expected to move through the midstate between 2 and 10 p.m., according to Met-Ed meteorologists.

The energy provider is preparing for the storms by getting additional crews ready-including contract workers-to repair damage caused by heavy winds, said Met-Ed spokesman Scott Surgeoner.

Crews will work throughout the day, as long as there's no lightening, to restore outages, he said.

As of 9 a.m., Met-Ed reported 8,585 York County customers were without power.

Areas hardest hit by the Thursday morning outages included Springettsbury Township with 1,130 outages, followed by West Manchester Township with 1,106 outages, Dover Borough with 1,096 outages and Dover Township with 907 outages.

All other municipalities had between one and 300 outages.

Most outages were caused by heavy winds knocking down trees, branches and power lines, Surgeoner said.

Met-Ed expected to have power restored to those customers by mid-morning.

But it may only be on for a short time.

"It's quite possible those same customers will be without power again this afternoon when the second wave of storms hits," Surgeoner said. "Our meteorologists said the storms we are expecting this afternoon and evening will be severe enough to knock out power again.

The energy provider serves nearly 172,000 customers in York County.

PPL, which serves about 8,000 customers in York County, reported 11 local customers were without power on Thursday.
