A total of 3,688 households in northern and Down East Maine remained without power Sunday night following tropical storm Arthur’s brush through the state Saturday.

The Emera Maine power company, which provides electricity in Aroostook, Hancock, Penobscot, Piscataquis and Washington counties, said Massachusetts workers joined its crews Saturday night in restoring power knocked out by high winds and falling trees.

Shortly before 9 p.m. Sunday, the company said the outages included 2,735 customers in Washington County, 862 in Hancock County and 168 in Aroostook County. Emera Maine estimated that power would be back by midday Tuesday in Hancock County and by the end of the day Tuesday in the Machias area and elsewhere in Washington County. About 20,000 Emera Maine customers lost power during the storm at one point.

As of 9:30 p.m. Sunday, power had been restored to all but 123 of the 6,000 Central Maine Power Co. customers who were left in the dark by the storm.
