The National Weather Service posted a wind advisory for parts of the Big Island and Kahoolawe until 6 a.m. Thursday.
Forecasters say deep high pressure far north of the state will produce windy and gusty conditions over and downwind of terrain on the Big Island and on Kahoolawe. A downward trend in wind speed will occur in the early morning hours on Thursday.
Winds are forecast to be easterly at around 20-to-30 mph with localized wind gusts over 50 mph. Winds will be strongest over the ridge tops and to the west of terrain and will not affect the Hilo area.
A wind advisory means that sustained winds of at least 30 mph or gusts of at least 50 mph are expected.
