High tides could cause minor coastal flooding for all Hawaiian Islands over the next few days, the National Weather Service warned Monday.

Vulnerable low-lying coastal roadways, docks, boat ramps, marina parking lots and other coastal infrastructure for all islands could see flooding during afternoon hours around peak high tide through Wednesday.

Impacts may also include flooding of beaches that are normally dry, minor coastal erosion and saltwater inundation.

The weather service warned against driving through flooded roadways, though it advised anyone who does have to drive through saltwater to rinse their vehicles with fresh water afterwards.

Electronics, vehicles or other valuables should also be moved to higher ground.

Mariners should also monitor vessels to ensure mooring lines don’t get too tight and should be aware of overwash around boat ramps. Canoes or other watercraft stowed on beaches should be secured.

Members of the public can also submit coastal flooding photos to the University of Hawai’i Sea Grant College Program’s Hawai’i and Pacific Islands King Tides Project, which aims to document high water level events, also known as king tides, to better understand future impacts from sea level rise and other coastal hazards.

King tides are the highest astronomical tides of the year and typically occur during the summer around July and August and winter around December and January in conjunction with new moons and full moons.
