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 low pressure system generated a large, long period northwest swell earlier in the week. This swell will begin affecting the islands later tonight, and rapidly build to warning levels today.
Expect surf, along north facing shores of Molokai and Maui to peak at to 25 to 30 feet tonight and Monday. Also expect surf along west facing shores of Molokai, building to 15 to 20 feet tonight and Monday. Warning level surf is expected to rapidly build by midday Sunday across Maui county.
Forecast surf heights are estimates of the height of the face or front of waves.
IMPACTS: 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.
PRECAUTIONARY MEASURES: 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.
