Description:
...HIGH SURF ADVISORY FOR ALL SOUTH FACING SHORES THROUGH TONIGHT...
...COASTAL FLOODING DURING HIGH TIDES THROUGH TONIGHT...
.The combination of a moderate to large, long-period south-
southwest (200- 180 degrees) swell and King Tides will cause wave
run up and could cause local coastal flooding during the
late afternoon and early evening high tide cycle 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 7-10 feet. Wave run up expected during the peak
high tide during the afternoon and early evening hours. A
combination of surf and high water levels could produce nuisance
coastal flooding.
* WHERE...South facing shores of all Hawaiian Islands.
* WHEN...through tonight.
* IMPACTS...Flooding of beaches that are normally dry, minor
coastal erosion, and saltwater inundation. Moderate. Strong
breaking waves and strong currents will make swimming
dangerous.
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.
Heed all advice from ocean safety officials. When in doubt, don't
go out.
