Crews were working to bring back electricity to thousands of homes in Atlantic Canada Sunday after post-tropical storm Arthur swept through the area.

More than 130,000 customers of New Brunswick Power and 90,000 Nova Scotia Power households had no electricity on Sunday morning as the storm moved out over the Gulf of St. Lawrence. Nova Scotia Power said on Twitter that some customers may be in the dark until July 8.

Arthur was moving northeast with winds of 75 kilometers (47 miles) an hour about 75 kilometers northwest of Port-Aux- Basques, Newfoundland, at 8 a.m. New York Time, the Canadian Hurricane Centre said. The forecaster ended its tropical storm warnings for the area.

Arthur hit North Carolina on Friday as a hurricane and slowed as it moved up the coast, disrupting Independence Day festivities and causing power outages. It struck Nova Scotia after the U.S. National Hurricane Center downgraded it to a tropical and then post-tropical storm.

The Cavendish Beach Music Festival on Prince Edward Island canceled Saturday performances because of the high winds. It said today the event was back on track. “The show is on,” organizers wrote on Twitter.
