Breezy Thanksgiving Forecast
A Wind Advisory is in effect until 6 p.m. this evening for winds out of the northeast from 20 to 35 mph, gusting to 50 mph across the Kohala and Kamuela areas on the north end of the Big Island, south of Volcano along the Kau coast and near South Point. The advisory may need to be extended if strong winds persist. Winds this strong can bring down tree branches and make driving difficult, especially for high profile vehicles.
A Small Craft Advisory is posted for all Hawaii County waters until 6 p.m. today. Winds of 20 to 25 knots are expected and rough seas from 10 to 15 feet. Inexperienced mariners should avoid navigating in these conditions.
A Marine Weather Statement has been issued by the National Weather Service for north facing harbors, including Kahului harbor. A large north-northeast swell will continue to affect these areas producing moderate surges and large breaking waves. Mariners should exercise caution when operating vessels inside harbors or near harbor entrances.
A High Surf Advisory is in effect for the north and east facing shores of the Big Island for a larger than expected north-northeast swell. Surf along north facing shores could reach heights of 12 to 15 feet. Surf along east facing shores could reach heights of 8 to 12 feet. The advisory is set to expire at 6 p.m. on Thursday.

Looking Ahead to the Thankgiving Holiday Weekend
Your Thanksgiving forecast calls for trade wind weather with showers focusing in windward and mauka areas in the morning and evening hours and leeward spots getting lots of morning sunshine. Winds will be breezy through the weekend. Winds may approach or reach advisory criteria in some areas such as Kohala Thursday through Friday. A wetter trade wind day may come Friday when the remnants of an old front reach us. Otherwise, we are looking at a relatively dry trade wind weather regime for the rest of this week and the weekend. The forecast will be updated daily and as necessary so check back for any changes.
