The National Weather Service has issued a wind advisory, which will be in effect from 6 a.m. Friday to 6 p.m. Saturday.
Strong high pressure to the northeast of the islands will combine with a very stable atmosphere to produce strong and gusty trade winds.
Northeast to east winds will increase to 15 to 30 mph with gusts to 50 mph. Gusts to 60 mph are expected over the summit of Haleakala.
Winds will be strongest over mountain ridges and high terrain, and downslope of the mountains.
Gusts this strong will cause loose objects to blow around and could result in downed tree branches. Localized power outages are possible.
