(BIVN) – Water levels are running around half a foot higher than predicted at the Honolulu tide gage, prompting a Special Weather Statement from the National Weather Service in Honolulu.

“An area of above normal ocean water levels, up to 6 inches in some locations, continues to slowly move through the Hawaiian Islands,” forecasters wrote in a National Weather Service discussion published at 8:40 p.m. HST. The rising water may contribute to coastal flooding.

The National Weather Service issued the following Special Weather Statement on these tidal anomalies:

Coastal flooding is possible this week along all shores of the main Hawaiian Islands due to unusually high water levels. The greatest potential for coastal flooding impacts will be during the peak high tides from Tuesday through Friday, which will occur before sunrise during the early morning hours. Visit tidesandcurrents.noaa.gov for more specific informations about forecast tides and water levels in your area.



Impacts of the high 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 for coastal flooding will diminish late in the week as the peak daily tides diminish.

We will update this page on Tuesday.
