The National Weather Service has issued a wind advisory from 6 am Saturday through Sunday morning.

East winds 25 to 30 mph are in the forecast, with localized gusts over 45 mph expected.

Areas of impact include the northern, eastern and southern portions of the Big Island along with the entire district of Kohala. The strongest winds will be felt near mountain tops and passes, trade wind-exposed areas, and around incoming showers.

Winds this strong can tear off shingles, knock down trees and large tree branches, blow away loose objects, tents and awnings. High profile vehicles may have difficulty steering at times.

Historically, after a period of very heavy rainfall and saturated soils, wind speeds similar to what is expected has caused property damage and power outages from fallen trees.


Watch out for falling tree branches when walking or driving. Residents and businesses are urged to take appropriate actions to protect their property. Make sure to secure loose objects, tents and awnings or take them down. Be prepared for power outages.
