More than 90 percent of Wareham's electrical customers are still without power Saturday evening after a nor’easter delivered near hurricane-force winds the day before.

As of 6 p.m., 13,747 customers were without power, representing 92 percent of the town, according to Eversource. Earlier in the day, the power company reported that 99 percent of residents were in the dark.

Saturday afternoon, an alert from Eversource reported that due to significant damage, "some customers may experience extended outages."

Town Administrator Derek Sullivan said local officials were waiting to hear from Eversource on when they could expect power to be restored.

"It's been a difficult storm," said Sullivan. "And there's a concern that a second storm will move into the area on Wednesday. We'll be watching that as well."

Eversource noted crews are at work across the South Coast. Eversource reports that in neighboring Marion all customers are without power. In Bourne, 68 percent of the town is without power and in Rochester that number is 95 percent.

“Eversource tree and line crews, assisted by thousands of support personnel, are working non-stop to repair the destruction caused by the high winds, rain and snow that continue to sweep through the region today,” Eversource said in a statement. “The damage caused by the storm is extensive and widespread.”

Eversource reminds customers to always stay clear of downed wires and to report them immediately to 9-1-1. Customers can report an outage online at www.eversource.com, or by calling 800-592-2000.

Anyone smelling the odor of natural gas due to broken lines should report it immediately to Eversource at 1-800-592-2000. Natural gas is non-toxic, colorless, tasteless, and odorless and has a distinctive, pungent odor – similar to rotten eggs – added so it can provide an easily recognized warning that gas is escaping.

Additionally, customers who are using a generator are reminded to be sure the generator is located well away from their home or business and that the transfer switch is working properly.
