Special Statement
Issued: 3:50 AM HST Jul. 21, 2017 – National Weather Service

... Coastal flooding possible...

Coastal flooding associated with King tides will be a
possibility during the next few days. The greatest potential for
coastal flooding impacts will be during the mid to late afternoon
hours through Monday, when the highest tides are expected. Visit
tidesandcurrents.NOAA.Gov for more specific information about
forecast astronomical tides and water levels in your area.

Note that east swell energy, which was generated by tropical
cyclone Fernanda, will produce elevated surf along east facing
shores through this weekend. This will likely cause greater wave
run-up along some exposed windward coastlines, especially during
high tide.

Impacts of the King tides may include flooding of beaches that
are normally dry, salt water inundation of typically vulnerable
low-lying roads, docks, boat ramps and other coastal
infrastructure. The potential threat for coastal flooding will
eventually be reduced early next week as the peak daily tides
diminish.
