... Coastal flooding possible through the weekend...

Coastal flooding, associated with a combination of high tides and
higher than normal water levels, will be possible through the
weekend. Coastal flooding impacts will be greatest during the peak
daily high tide, which will occur during the mid- to late-
afternoon hours the next several days.

Observed water levels at the Honolulu tidal station continue to be
much higher than predicted, and are currently running about 1.0
feet higher than predicted values. Visit tidesandcurrents.NOAA.Gov
for observed and forecast tides and water levels in your area.

Impacts may include flooding of beach areas that are normally
dry, salt water inundation of typically vulnerable low-lying
roads, docks, boat ramps and other coastal infrastructure. The
potential for coastal flooding will diminish by the middle of next
week as the peak daily tides diminish.
