Wildfires in Hawaii fanned by strong winds burned multiple structures, forced evacuations, and caused power outages in several communities late Tuesday.

Iran PressAmerica: 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 for Gov. Josh Green, who is traveling, and activated the Hawaii National Guard.

Fire crews on Maui were battling multiple blazes concentrated in two areas: the popular tourist destination of West Maui and an inland, mountainous region. County of Maui spokesperson Mahina Martin said in a phone interview late Tuesday that it wasn't immediately known how many buildings had burned.

Because of the wind gusts, helicopters weren't able to dump water on the fires from the sky — or gauge more precise fire sizes — and firefighters were encountering roads blocked by downed trees and power lines as they worked the inland fires, Martin said.

Hawaiian Electric reported Tuesday night that about 13,000 customers in Maui were without power.
