...HIGH SURF ADVISORY FOR SOUTH FACING SHORES OF NIIHAU KAUAI OAHU MOLOKAI MAUI AND BIG ISLAND THROUGH MONDAY NIGHT AND COASTAL FLOODING DURING HIGH TIDE THROUGH TUESDAY... .A long-period south southwest (200 degree) swell will build tonight and peak Sunday night into Monday before gradually declining through the rest of the week. South and west shorelines will be impacted by the resulting surf, with south shores reaching advisory level heights. Surf heights may also approach warning levels along south facing shores (advisory for west facing shores) during the peak of this event. King Tides, or the highest monthly tides, are running higher than predicted will lead to minor flooding along all shoreline and in low-lying coastal areas. Coastal flooding is possible around the daily peak tide, which will occur during the late afternoon and early evening hours. The combination of the swell, King Tides and the daily high tide will make low- lying coastal areas along south and west shores susceptible to more widespread coastal flooding. * WHAT...For the High Surf Advisory, surf of 8 to 12 feet late tonight and 10 to 14 feet Sunday afternoon through Monday night. For the Coastal Flood Statement, minor coastal flooding. * WHERE...South facing shores of Kahoolawe, Kauai, Lanai, Maui, Molokai, Niihau, Oahu and the Big Island. Vulnerable low-lying coastal roadways, docks, boat ramps and other coastal infrastructure. * WHEN...For the High Surf Advisory, from 6 PM this evening to 6 AM HST Tuesday. For the Coastal Flood Statement, through Tuesday evening. * IMPACTS...Moderate to high. Strong breaking waves and strong currents will make swimming dangerous. Flooding of beaches that are normally dry, minor coastal erosion, and saltwater inundation. * ADDITIONAL DETAILS...The combination of the incoming south southwest swell and King Tides over the next couple of days will result in more widespread coastal shore impacts particularly during the afternoon and evening peak daily tide.

Heed all advice from ocean safety officials. When in doubt, don't go out. Do not drive through flooded roadways. Owners of properties in low-lying shoreline areas or near waterways should consider moving any electronics, vehicles, or other valuables to higher ground. Boaters should monitor vessels to ensure mooring lines don't get too tight and be aware of overwash around boat ramps at high tide. Any recreational watercraft on beaches, such as canoes, should be secured or moved.
