UPDATE: Wind advisory in effect today through Sunday for lower elevations of Big Island

Update at 4:16 a.m. March 13, 2026: A wind advisory is now in effect from 6 a.m. today (March 13) to 6 a.m. Sunday (March 15) for lower elevations of the Big Island as a powerful kona low continues its slow march through the islands.

Forecasters report that southwest winds 25 to 35 mph — with gusts to about 50 mph — are expected, with communities north and east of steep mountain slopes most at risk of the strongest winds.

Winds that strong can tear off shingles, knock down tree branches, blow away tents and awnings and make it difficult to steer, especially for drivers of high profile vehicles.

The public is advised to watch out for falling tree branches; make sure tents, awnings and other loose outside items that could get tossed around by the wind are secure or taken down; and be prepared for power outages.

A winter storm warning also remains in effect for Big Island summits above 12,000 feet, with a high wind warning still in effect atop Mauna Kea and Mauna Loa as well.

Southwest winds of 55 to 75 mph, with gusts of up to 110 mph, are expected at the summits which only increase the potential for blizzard conditions, including blowing snow that will significantly reduce visibility to near zero at times.

Total snow accumulation of 12 to 18 inches is possible at both summits.

Update 12:33 p.m. on March 11, 2026: A high wind watch is now also in effect for lower elevations of the Big Island from Friday morning to Saturday night.

Southwest winds of 25 to 35 mph with gusts up to 60 mph are expected, according to the National Weather Service in Honolulu. Islandwide strong winds are possible, but areas most at
risk are those located north and east of steep mountain slopes.

Damaging winds could blow down trees and power lines. Widespread power outages are possible. Travel could be difficult, especially for high-profile vehicles.

A winter storm watch is currently in place for Big Island summits.
