WHAT
For the High Surf Warning, dangerously large breaking waves of 10 to 15 feet. Significant wave run up expected during the peak high tide during the afternoons. For the Coastal Flood Statement, isolated minor coastal flooding.
WHERE
South facing shores of all Hawaiian Islands. Vulnerable low-lying coastal roadways, docks, boat ramps and other coastal infrastructure.
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.
ADDITIONAL DETAILS
The combination of the south-southwest swell and King Tides over the next two days will result in more widespread coastal shore impacts, particularly during the afternoon and evening peak daily tide.
PRECAUTIONARY/PREPAREDNESS ACTIONS
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.
