Description: 
...HIGH SURF WARNING FOR ALL SOUTH FACING SHORES THROUGH TUESDAY MORNING... ...COASTAL FLOODING DURING HIGH TIDES THROUGH TUESDAY... .The combination of a large, long-period south-southwest (200-190 degrees) swell and King Tides will cause significant wave run up and could cause widespread coastal flooding during the afternoon high tides along south facing shores. Also due to the highest monthly tides and water levels running higher than predicted at select areas, flooding along all shorelines and in low-lying coastal areas are expected especially during the late afternoon and early evening hours. * WHAT...Surf 10 to 15 feet. Significant wave run up expected during the peak high tide during the afternoons. A combination of surf and high water levels could produce nuisance coastal flooding. * WHERE...South facing shores of all Hawaiian Islands. * WHEN...For the High Surf Warning, until 6 AM HST Tuesday. For the Coastal Flood Statement, through Tuesday 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.
Instruction: 
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.
