Shoppers at the Coventry Mall in Chester County had to leave Thursday night because the power went out.

It happened around 8:30 p.m. at the mall, located at 351 W. Schuylkill Rd. in North Coventry Township, just outside Pottstown.

Crews on the scene said there was a big flash in the area before the power outage.

It's unclear whether the outage was due to the ice in the area. Chester County was the hardest hit by Wednesday's storm.

A post on the mall's Facebook page said it would remain closed until further notice.
