...HIGH SURF WARNING IN EFFECT UNTIL 6 PM HST SATURDAY FOR NORTH AND WEST FACING SHORES OF NIIHAU KAUAI OAHU AND MOLOKAI... ...HIGH SURF ADVISORY IN EFFECT UNTIL 6 PM HST SATURDAY FOR NORTH FACING SHORES OF MAUI AND WEST FACING SHORES OF THE BIG ISLAND... ...COASTAL FLOOD STATEMENT IN EFFECT FOR ALL HAWAIIAN ISLANDS... .Two significant northwest swells will impact the islands over the next couple of days. The first moderate to large, long period northwest swell is peaking early this morning. The second overlapping, larger, long period northwest swell will build in today and peak late this afternoon into Saturday before subsiding through the rest of the weekend. This second swell will push surf heights above warning levels from late today into Saturday for exposed shores. A combination of large surf and higher than predicted water levels will lead to flooding of beaches that typically remain dry, especially at and around the peak daily tide. ...COASTAL FLOOD STATEMENT REMAINS IN EFFECT THROUGH MONDAY AFTERNOON... * WHAT...For north facing shores, surf building to heights in the 20 to 30 foot range by this afternoon. For west facing shores, surf building to heights in the 20 to 25 feet by this afternoon. Additionally, a combination of surf and high water levels will produce nuisance coastal flooding. * WHERE...North and west facing shores of Niihau, Kauai, Oahu, and Molokai. * WHEN...For the High Surf Warning, until 6 PM HST Saturday. For the Coastal Flood Statement, through Monday afternoon. * IMPACTS...High. Expect very strong breaking waves and powerful currents. Waves breaking in channel entrances may make navigating the channels dangerous. Flooding of beaches that are normally dry, minor coastal erosion, and saltwater inundation.

Avoid driving through flooded roadways. If you are forced to drive through salt water, be sure to rinse your vehicle with fresh water. Move electronics, vehicles or other valuables to higher ground. Monitor vessels to ensure mooring lines don't get too tight and watch out for overwash around boat ramps. Secure canoes or other watercraft stowed on beaches. Stay away from the shoreline along the affected coasts. Be prepared for road closures. Postpone entering or leaving channels affected by the high surf until the surf subsides.
