Watches & Warnings

Special Statement
Issued: 5:00 AM HST May. 27, 2017 – National Weather Service

... Coastal flooding anticipated in conjunction with record-level
King tides and elevated surf along south facing shores...

Coastal flooding impacts associated with record-level King tides
will continue each day along all shores through the Memorial Day
Holiday weekend. Beaches and shorelines, boat ramps and docks, and
vulnerable low-lying roads and structures will be impacted by
coastal flooding through the late afternoon and early evening

The following are the daily forecast tide levels and times for
Honolulu which will correspond to coastal flooding impacts. Be
advised that observed tides have been running much higher than
these values.

5/27 today 5:55 PM HST 2.4 feet (advisory level South Shore surf)
5/28 Sunday 6:46 PM HST 2.3 feet (advisory level South Shore surf)
5/29 Monday 7:40 PM HST 2.1 feet (south shore surf gradually lowering)

Maui County shorelines can expect similar impacts around the
times of high tides. Please visit the website
tidesandcurrents.NOAA.Gov for more information about water levels
in your area.

In addition to the coastal flooding impacts, a long-period south-southwest
swell will continue to generate elevated surf along south facing shores
into late Sunday. Therefore, a high surf advisory remains in effect for
south facing shores of all islands through Sunday afternoon. The combination
of large surf and high water levels will result in additional wave run up
along south facing coastlines, likely flooding beaches that typically remain
dry and exposed during typical high surf events along southern shorelines.
Please see the coastal hazard message (cfwhfo) on our website for more
information regarding surf related hazards along south facing shores.

Surf heights and water levels are forecast to gradually trend back
toward normal values early next week.
