A High Surf Advisory is posted for north facing shores from 6:00 p.m. this evening through 6:00 a.m. Thursday for a north swell building tonight and peaking Wednesday before gradually diminishing. Expect strong breaking waves, shore break and strong longshore and rip currents making swimming difficult and dangerous.
A Wind Advisory is posted for the summits of Mauna Kea and Mauna Loa through 6:00 a.m. Wednesday for northwest to north winds from 35 to 50 mph with higher gusts. Winds will be strongest over the highest elevations and summit peaks mainly above 11,000 feet. The National Weather Service advises that winds this strong can make walking and driving difficult. Use extra caution when driving and be careful when opening and closing doors. If camping in the area, be sure your tent is well anchored.
