HONOLULU (AP) Wildfires in Hawaii fanned by strong winds burned multiple structures, forced evacuations and caused power outages in several communities late Tuesday as firefighters struggled to reach some areas that were cut off by downed trees and power lines.

The National Weather Service said Hurricane Dora, which was passing to the south of the island chain at a safe distance of 500 miles (805 kilometers), was partly to blame for gusts above 60 mph (97 kph) that knocked out power as night fell, rattled homes and grounded firefighting helicopters.

Acting Governor Sylvia Luke issued an emergency proclamation on behalf of Gov. Josh Green, who is traveling, and activated the Hawaii National Guard.
