UPDATE: 3:30 p.m.

Hawaiian Electric crews continue to work on restoring storm-related power outages affecting customers on Hawaii island, Oahu and Maui.

As of 3 p.m. there were 12,476 customers without power. Earlier there were 18,150 customers affected.

Hawaii island still has about 10,000 customers without power in North Kohala, Volcano and Punaluu, Maui County has about 700 customers affected in parts of Upcountry Maui, and Oahu has 1,776 customers without power in Punchbowl and Manoa.

Hawaiian Electric said customers in Upcountry Maui should prepare for an extended outage, possibly overnight, as crews work to restore power lines brought down by the storm. On Hawaiii island, power is expected to be restored to North Kohala by 7 p.m. and in the Volcano area by 10:30 p.m. Heavy rains and wind may delay the ability to safely make repairs, the utility said. Crews are unable to access the Punaluu area due to road closures caused by flooding.

Customers who live outside these areas and are without power are asked to call Hawaiian Electric’s Trouble line.

If you see a downed power line, assume it is energized and dangerous. Stay at least 30 feet or more away from all power lines. Warn others to stay away. For emergency assistance call 911. For Hawaiian Electric, call Hawaiian Electric’s trouble line:

An equipment failure at the Iwilei substation on Oahu caused an outage at about 5 a.m. from downtown Honolulu to Chinatown, according to a news release. Workers repaired and restored power to customers after 10 a.m.

Meanwhile, a car that hit a separate high-voltage transformer in a parking garage caused a separate downtown outage at about 3:40 a.m.
