Hawaiian Electric said Thursday that it is mobilizing all available resources including extra personnel, helicopters and heavy equipment to restore power as quickly and safely as possible.

As of 4 p.m. Thursday, about 220 customers in Maui County remained without power after crews restored service to about 70 customers. People lost power as a powerful storm brought heavy rain and high winds to Maui County last week.

Work included the use of a helicopter in East Maui to install a 55-foot pole and transport equipment into areas inaccessible by truck, along with repairs in other parts of the island.

However, with a new storm approaching, customers are being asked to prepare for potential extended or new outages.
