High Surf, Coastal Flooding Warnings Extended for All Hawaiian Islands

A high surf advisory remains in effect for all major Hawaiian Islands, as does a coastal flood warning.

A declining north swell will continue to produce large surf along north-facing shores. Strong southerly winds generating rough, short period chop along south-facing shores and coinciding with astronomical high tides during the pre-dawn hours will increase the potential for the nuisance flooding of low-lying areas and local area roadways.

Isolated minor coastal flooding expected, including flooding of beaches that are normally dry, minor coastal erosion and saltwater inundation.

Avoid driving through flooded roadways. If you are forced to drive through salt water, be sure to rinse your vehicle with fresh water. Move electronics, vehicles or other valuables to higher ground. Monitor vessels to ensure mooring lines don’t get too tight and watchout for overwash around boat ramps. Secure canoes or other watercraft stowed on beaches.
