Just over 2,000 Unitil customers woke up Sunday morning in the dark, according to the utility's outage map but power was restored just before 9 a.m.

The towns most affected included Brentwood, East Kingston, Exeter and Kingston. There was also an outage in Atkinson and Plaistow which cleared up by 8 a.m. according to the outage map.

Just before 9 a.m. most of the rest of the power was restored.

"The cause is still under investigation. The fault occurred on a sub-transmission line. What crews were able to do is switch around it to bring customers back online," Unitil spokesman Alec O'Meara told Seacoast Current.

The sub-transmission line was off-road in Exeter and crews continued patrolling the line to find the fault, according to O'Meara.

The outages were first reported around 6:30 a.m., shortly after a thunderstorm moved through the area.

The thunderstorms moved through in the 6 a.m. hour with heavy rain and winds that briefly gusted to 31 mph, according to National Weather Service Meteorologist Michael Clair.

Eversource, Liberty Utilities and NH Electric Co-op did not have any Seacoast outages.
