Expected
Effective:
June 15, 2026 - 6:40pm
Expires:
June 16, 2026 - 7:45am
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.
