The elevated tides will also contribute to runup and beach erosion late tonight into early Sunday morning along north and west shores exposed to the large swell. * WHAT...For north facing shores of Maui, surf of 12 to 16 feet, slowly decreasing late tonight. For west facing shores of the Big Island, surf of 6 to 8 feet, slowly decreasing late tonight. Additionally, a combination of higher than predicted tides and elevated surf will produce nuisance coastal flooding, mainly during peak high tides in the early morning hours between midnight and sunrise. * WHERE...North facing shores of Maui and west facing shores of the Big Island. * WHEN...For the High Surf Advisory, until 6 AM HST Sunday. For the Coastal Flood Statement, through Monday afternoon. * IMPACTS...Moderate. Strong breaking waves and strong currents will make swimming dangerous.
