Sunday on Big Island: High surf warning for south shores, coastal flooding during high tides

With dangerously large breaking waves of 10 to 15 feet forecast, a high surf warning for south-facing shores of the Big Island has been issued until 6 a.m. Tuesday.

The National Weather Service also said there also is the potential for coastal flooding during high tides through Tuesday due to a combination of a large long-period south-southwest swell and King Tides.

Due to the highest monthly tides and water levels running higher than predicted at select areas, flooding along all shorelines and in low-lying coastal areas are expected especially during the late afternoon and early evening hours of Sunday.

Due to the high surf warning and coastal flooding, Kahaluʻu, Laʻaola (Magic Sands) and Kohanaiki beach parks are closed Sunday. Other beach parks may close without notice, according to Hawaiʻi County officials.

Be aware that beaches could experience wave run-up and wash-over, especially during high tide.

Hawaiʻi County also warns beachgoers to heed all instructions given by Ocean Safety officials. Remember, when in doubt, don’t go out.

Impacts are expected to be moderate to high, with strong breaking waves and strong currents making swimming dangerous along the advisory shores.

The National Weather Services also warns people to 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 watch out for overwash around boat ramps. Secure canoes or other watercraft stowed on beaches.
