EVENTS: The National Weather Service in Honolulu 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. Friday.
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: Large northwest swell will continue to produce dangerous surf conditions along exposed beaches overnight into early Thursday. Reinforcing northwest swell will push surf heights well above warning levels Thursday afternoon through Friday afternoon. The surf will drop below warning levels Friday evening, however will remain elevated above advisory levels Saturday then reach warning levels again Sunday.
Surf along north facing shores will be 10 to 15 feet through Thursday morning building to 25 to 35 feet Thursday afternoon and evening. Surf along west facing shores will be 8 to 12 feet through Thursday morning, building to 15 to 25 feet Thursday afternoon and evening.
Forecast surf heights are estimates of the height of the face or front of waves.
PRECAUTIONARY MEASURES: 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 DANGEROUS. 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 BE AWARE OF AN INCREASED NUMBER OF SURFERS AND BODY BOARDERS UTILIZING THE HARBOR CHANNEL TO ACCESS SURFING AREAS.
