Emera Maine is investigating the cause of a power outage that affected more than 4,000 customers in the Corinth area.

UPDATE: Emera Maine reports power has been restored to the area. There's no word, at this point, about what caused the outage.

It's never a convenient time for a power outage but, when temperatures dip into the single numbers, can become dangerous fast. Crews are traveling to a substation in Corinth to investigate the cause of the outage that's affecting more than 4,700 customers and, officials say will work to get the power on as quickly and safety as possible.

Customers are reminded that it's never safe to touch a downed power line or a tree that's in contact with a downed line. In addition, officials ask that motorists slow down and, if possible, move into the next lane when passing utility crews who are working to restore power. Anyone using a generator or alternative heating source is reminded to ensure they're being operated per manufacturer's guidelines at all times to prevent injury to the line workers, and are properly vented to avoid CO poisoning.
