Coastal Flood Statement issued January 30 at 9:08AM HST until February 2 at 6:00PM HST by NWS Honolulu HI
...HIGH SURF WARNING IN EFFECT UNTIL 6 PM HST SATURDAY FOR NORTH
AND WEST FACING SHORES OF NIIHAU KAUAI OAHU AND MOLOKAI...
...HIGH SURF ADVISORY IN EFFECT UNTIL 6 PM HST SATURDAY FOR NORTH
FACING SHORES OF MAUI AND WEST FACING SHORES OF THE BIG ISLAND...
...COASTAL FLOOD STATEMENT IN EFFECT FOR ALL HAWAIIAN ISLANDS...
.Two significant northwest swells will impact the islands over
the next couple of days. The first moderate to large, long period
northwest swell is peaking early this morning. The second
overlapping, larger, long period northwest swell will build in
today and peak late this afternoon into Saturday before subsiding
through the rest of the weekend. This second swell will push surf
heights above warning levels from late today into Saturday for
exposed shores. A combination of large surf and higher than
predicted water levels will lead to flooding of beaches that
typically remain dry, especially at and around the peak daily
tide during the early morning hours between midnight and sunrise.
* WHAT...For north facing shores, surf building to 20 to 30 feet
this afternoon and persisting into tonight. For west facing
shores, surf building to 20 to 25 feet this afternoon and
persisting into tonight. Additionally, a combination of surf and
high water levels will produce nuisance coastal flooding, mainly
during peak high tides in the early morning hours between
midnight and sunrise.
* WHERE...North and west facing shores of Niihau, Kauai, Oahu,
and Molokai.
* WHEN...For the High Surf Warning, until 6 PM HST Saturday. For
the Coastal Flood Statement, through Monday 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...
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.
