EVENTS: The National Weather Service has continued the HIGH SURF WARNING for NORTH and WEST FACING SHORES of MOLOKAI and NORTH FACING SHORES of MAUI, in effect until 6:00 p.m.
A High Surf Warning means that dangerous, battering waves will pound the shoreline. This will result in very dangerous swimming conditions, and deadly rip currents.
EFFECTS: A powerful storm off Kamchatka Peninsula a few days ago has generated a very large northwest swell which will persist at least through today. This swell will begin to subside tonight, but a high surf advisory will very likely be needed tonight and Thursday.
Expect surf of 20 to 30 feet tonight along north facing shores of Molokai and Maui, with some higher sets. Surf will begin to subside this afternoon but will remain above warning levels. Surf will be 12 to 22 feet with some higher sets today along west facing shores of Molokai.
Forecast surf heights are estimates of the height of the face or front of waves.
IMPACTS: Expect sea water occasionally sweeping across portions of beaches, with very strong breaking waves and strong longshore and rip currents. Breaking waves may occasionally impact harbors, making navigating the harbor channel dangerous.
PRECAUTIONARY MEASURES: STAY OUT OF THE WATER AND WELL AWAY FROM THE SHORE BREAK ALONG THE AFFECTED SHORES. LARGE BREAKING SURF, SIGNIFICANT SHOREBREAK AND DANGEROUS CURRENTS MAKE ENTERING THE WATER VERY HAZARDOUS. ANYONE ENTERING THE WATER COULD FACE SIGNIFICANT INJURY OR DEATH. BOATERS SHOULD BEWARE OF WAVES BREAKING IN HARBOR ENTRANCES AND WATCH OUT FOR SURFERS AND BODY BOARDERS USING HARBOR CHANNELS TO ACCESS SURFING AREAS.
