...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...Isolated minor coastal flooding.
* WHERE...Vulnerable low-lying coastal roadways, docks, boat ramps
and other coastal infrastructure.
* WHEN...Around the daily peak tides during the late afternoon and
early evening hours through Tuesday evening.
* IMPACTS...Flooding of beaches that are normally dry, some minor
coastal erosion, and saltwater inundation of low-lying roads,
docks, boat ramps, and other coastal infrastructure.
