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 from until 6:00 a.m. Sunday.
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 strong low, northwest of the Islands, has generated a large northwest swell that will arrive today and peak Saturday before gradually diminishing.
Surf along north facing shores will build to heights of 12 to 18 feet late this morning and afternoon, peaking at 25 to 35 feet Saturday. Surf along west facing shores will increase to 8 to 12 feet late this morning and afternoon, peaking at 15 to 25 feet on Saturday.
Forecast surf heights are estimates of the height of the face or front of waves.
IMPACTS: EXPECT OCEAN WATER SURGING AND SWEEPING ACROSS BEACHES, COASTAL BENCHES, AND LAVA FLOWS. POWERFUL LONGSHORE AND RIP CURRENTS WILL BE PRESENT AT MOST BEACHES. LARGE BREAKING WAVES AND STRONG CURRENTS MAY IMPACT HARBOR ENTRANCES AND CHANNELS CAUSING CHALLENGING BOAT HANDLING.
PRECAUTIONARY MEASURES: THESE DANGEROUS CONDITIONS MEAN THAT ONLY HIGHLY EXPERIENCED PERSONS SHOULD ENTER THE WATER. INEXPERIENCED PERSONS SHOULD REMAIN OFF BEACHES AND ADJACENT BEACHFRONT AREAS. LARGE BREAKING SURF, SIGNIFICANT SHOREBREAK AND DANGEROUS CURRENTS MAKE ENTERING THE WATER VERY HAZARDOUS. ANYONE ENTERING THE WATER COULD FACE SIGNIFICANT INJURY OR DEATH.

In other weather news, the National Weather Service in Honolulu has CANCELLED the FLOOD ADVISORY for the ISLAND OF MAUI. That advisory had been issued early today when a leading wave of heavy showers from an approaching cold front moved onshore across South Maui, moving to the northeast.
EFFECTS: Weather radar and rain gages showed that the heavy rains ended around 8 a.m. Thus the flood advisory is cancelled.
PRECAUTIONARY MEASURES: THE PUBLIC SHOULD REMAIN CAUTIOUS AND ALERT FOR ANY POSSIBLE FLOODING CONDITIONS. DON’T TRY TO CROSS FLOODED ROADWAYS OR FAST FLOWING STREAMS IN YOUR VEHICLE OR ON FOOT. IT MAY BE TOO DANGEROUS. TURN AROUND…DON’T DROWN.
INFORMATION: This will be the last Maui County Civil Defense notification on this event.
