Minor coastal flooding possible on Big Island during afternoon high tides through Tuesday

Residents and visitors along the Big Island’s coastline are being advised to prepare for minor coastal flooding during the afternoon high tides through Tuesday as elevated ocean water levels combine with peak monthly tides.

The National Weather Service in Honolulu has issued a Coastal Flood Statement for the island, warning that isolated flooding is possible in vulnerable low-lying coastal areas during the daily afternoon high tides.

Areas most susceptible include coastal roadways, docks, boat ramps and other shoreline infrastructure. Officials said beaches that are normally dry could experience flooding, while some locations may see minor coastal erosion and saltwater inundation.

Communities along the island’s east, southeast, south and north shores are among those that could be affected.

Motorists are urged to avoid driving through flooded roadways whenever possible. Saltwater can damage vehicles, and anyone who must drive through flooded areas should rinse their vehicle with fresh water afterward to reduce corrosion.

Boaters are encouraged to monitor vessels to ensure mooring lines remain secure but not overly tight as water levels rise. Officials also recommend securing canoes and other watercraft stored on beaches to prevent them from being swept away by higher water.

Residents living in flood-prone coastal areas should consider moving vehicles, electronics and other valuables to higher ground before the afternoon high tides arrive.
