The National Weather Service has issued a HIGH SURF ADVISORY for NORTH and WEST FACING SHORES of MOLOKAI and NORTH FACING SHORES of MAUI in effect from 9 p.m. this evening through 6 a.m. Wednesday.
A High Surf Advisory means that high surf will affect beaches in the advisory area, producing rip currents and localized beach erosion.
EFFECTS: A very large northwest swell will impact the islands this evening. A powerful storm off Kamchatka peninsula a few days ago has generated a very large northwest swell. This swell is expected to reach the Hawaiian Islands this evening and persist through early Wednesday morning, bringing warning level surf to the area.
Expect surf increasing to 20 to 30 feet along north facing shores of Molokai and Maui and increasing to 12 to 20 feet along west facing shores of Molokai.
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.
INFORMATION: Maui Civil Defense Agency will continue to monitor the situation. Please listen to your local radio and TV stations or NOAA Weather Radio broadcasts for any updates.
