Hazy Skies for Hilo, Pop up Showers Possible Today
A High Surf Warning is posted for east facing shores of the Big Island through 6 a.m. Wednesday with wave heights rising to 12 to 18 foot faces in some spots Tuesday. Expect ocean water occasionally sweeping across portions of beaches, very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel difficult. Large breaking surf, significant shore break and dangerous currents will make entering the water very hazardous. Boaters should be aware of an increased number of surfers in the water.
A Small Craft Advisory is posted for Big Island windward and southeastern waters as well as Alenuihaha channel through 6 a.m. Wednesday for rough seas up to 12 feet. Inexperienced mariners should avoid navigating in these conditions.
