The National Weather Service has extended the Wind Advisory through Monday at 6 p.m. Northeast winds from 30 to 50 mph with gusts up to 70 mph are expected. The strongest winds on the Big Island are expected on the summits of Mauna Kea and Mauna Loa, in leeward Kohala, the Waimea to Kawaihae corridor and near South Point and Upolu Point. Winds this strong can bring down tree branches and make driving difficult.

A Gale Warning is in effect for Big Island leeward and south waters and the Alenuihaha channel through Monday at 6 p.m. Northeast winds of 30 to 35 knots are expected with higher gusts. Rough seas of 12 to 18 feet are also forecasted. A Gale Warning means that these winds are imminent or occurring. Operating a vessel in gale conditions requires proper experience and equipment. Mariners without these things should remain in port until gale conditions end.

All areas not under the Gale Watch are under a Small Craft Advisory through 6 p.m. Monday. Rough seas of 10 to 17 feet are forecasted along with winds of 30 to 35 knots or more. Inexperienced mariners should avoid navigating in these conditions.

Mostly cloudy skies and likely showers are expected for windward and mauka areas. After the land breeze takes hold, mostly clear skies are expected on the Kona side with just isolated showers.

The peak nights for the Geminid Meteor Shower have passed but the shower is still active until December 19. Details on timing and viewing tips can be found HERE.

 

Looking Ahead 

Winds will be strongest where winds funnel, go downslope on the leeward sides and over coastal waters and channels. Gusty winds are expected at least through Monday morning. On Tuesday wind speeds are expected to ease slightly and the weather is forecasted to get back to more normal trade wind conditions. The next cold front should pass north of the state with little effect around midweek, then a new weaker high passing to our north should maintain moderate to locally breezy trades through next Friday. We may get enhanced showers on Wednesday and Thursday.
