(BIVN) – The High Wind Warning, High Surf Warning, and High Surf Advisory continue for Hawaiʻi Island, as a strong area of low pressure will continue to shift eastward, just to the north of the islands overnight, forecasters say.

The National Weather Service expects damaging high winds and surf to occur through the night for the Big Island.

The Hawaii Electric Light Company and Hawaiʻi County Department of Public Works report multiple trees and utility poles down in the Hāmākua District.

HELCO advises customers in Honokaʻa and Waipunahina to be prepared for “an extended outage due to hazardous weather conditions.”  Crews will continue with power restoration efforts when it is safe to do so.

“We know some customers have been without power most of today and into tonight,” HELCO wrote in a Tweet. “Extra crews are on the job and more will be called out in the morning. We are working to get your power back on as soon as we can. Thank you for your patience and understanding.”

Highway 19 was still closed as of Sunday between the 38 and 39 mile markers due to fallen trees and utility poles.  HELCO and State Highways are working to clear the roadway, civil defense says.
