Greatest Potential for Coastal Flooding from Astronomical Tides, Today and Friday

A special weather statement remains in effect for all shores of the main Hawaiian Islands, due to unusually high water levels and the possibility of coastal flooding.

Forecasters with the National Weather Service say the greatest potential for coastal flooding impacts will be this morning and on Friday, especially around the time of the peak high tide, which occurs between midnight and daybreak in most areas.

The higher than normal astronomical tides will gradually lower from Friday through the weekend.  Along with the diminished winds, this will lessen the potential for coastal  flooding.  The NWS says the special weather statement remains in effect through this weekend.
