A Small Craft Advisory is posted for all Big Island waters through 6:00 p.m. Wednesday for north winds up to 25 knots with higher gusts. Rough seas of 9 to 14 feet are also forecasted late tonight through Wednesday afternoon. Inexperienced mariners should avoid navigating in these conditions.
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 noon 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.

Looking Ahead
A very dry weather pattern is expected over the islands through the rest of this week and into the weekend. Breezy northeast are expected on Wednesday. Winds will veer easterly Wednesday night and weaken on Thursday. Light southeast flow will then prevail into the weekend resulting in land and sea breezes over the islands and periods of vog and haze. Rainfall will be almost nonexistent Wednesday, with a very gradual increase in moisture towards the end of the week. Temperatures will also gradually warm through the rest of the week.
