Coastal flood statement, high surf advisory issued for Kauaʻi, Niʻihau beginning at noon

The National Weather Service has issued a minor coastal flood statement for vulnerable low-lying coastal roadways and a high surf advisory for north- and west-facing shores of Kauaʻi and Niʻihau, effective at noon today.

Forecasters predict large breaking waves of 10 to 16 feet along north- and west-facing shores of Niʻihau and Kauaʻi. Peak monthly high tides, combined with higher-than-predicted water levels, could lead to minor flooding along the shoreline and in low-lying coastal areas.

The minor coastal flooding statement and the high surf advisory will be in effect from noon through Saturday morning. Coastal flooding is possible around the daily peak high tide, which will occur during the early morning hours.

According to the National Weather Service, minor flooding could affect coastal infrastructure such as docks and boat ramps and beaches that are normally dry, with minor coastal erosion and saltwater inundation. Strong breaking waves and currents will make swimming dangerous.

Ocean safety officials advise motorists to avoid driving through flooded roadways and to move electronics, vehicles, and other valuables to higher ground. If compelled to drive through salt water, rinse vehicles with fresh water.

Monitor vessels to ensure mooring lines do not become too tight, and watch for overwash around boat ramps. Secure canoes and other watercraft stored on beaches.
