Storms have left residents without power in several communities, and a flood warning has been issued for the Pemigewasset River at Plymouth.
Martin Murray of Public Service of New Hampshire said power was expected to be restored in Bethlehem, Carroll and Jefferson by 7 a.m. yesterday.
PSNH did not have an estimate of when power would be restored in Antrim, Derry, Jaffrey, Rindge and Twin Mountain.
The utility said spotty outages began throughout the state Saturday afternoon, and it received several hundred reports of outages Saturday night in southwest New Hampshire.
The National Weather Service expected the Pemigewasset to fall below flood stage by yesterday afternoon.
The state police said no storm-related incidents have been reported.
