A high-wind advisory has been issued for Sunday and Monday for Oahu, Lanai, Maui, Kahoolawe and the Big Island.

The National Weather Service said winds will be from the northeast at 20 to 35 mph, with gusts of more than 50 mph.

The advisory will be in effect from 6 a.m. Sunday through 6 p.m. Monday.

On Oahu, the strongest winds will affect the Koolau and Waianae mountain ridges and areas just leeward.

In Maui County, the strongest winds will be on Lanai, over Kahoolawe, over the West Maui mountains and in the central valley.

On Hawaii island, the strongest winds will be in the leeward Kohala area, the Waimea-Kawaihae corridor, the western saddle area, Hawaii Volcanoes National Park and South Point.

A wind advisory means sustained winds of at least 30 mph or gusts of at least 50 mph are expected.

“Motorists should use extra caution,” the weather service said.
