HALIFAX - Roughly 13,000 Nova Scotia Power customers were still without power Sunday morning after a storm ripped through the region Friday.

The utility said some people would have to wait until late Sunday evening for their lights to come back on.

Utility spokeswoman Bev Ware said at one point over the weekend, 67,000 customers were without power.

Nova Scotia Power said crews were grappling with heavy, wet snow that was built up on tree branches, causing them to droop over power lines.

The Cape Breton Regional Municipality had opened several warming centres across the island equipped with hot beverages and outlets for charges devices.
