An area of enhanced moisture will be reaching the islands Sunday afternoon and will move slowly from east to west, bringing an increase in showers. Most of the precipitation will be for windward and mauka areas, but the trade winds may push some of those showers leeward. Showers will continue overnight into most of Monday.
A High Surf Advisory is in effect until 6 p.m. Monday for all south-facing shores as a long-period swell is expected to bring waves of 5 to 8 feet, a little smaller than originally forecast but still borderline advisory level. West shores will see a wrap at 4 to 6 feet. There's also a Small Craft Advisory for Maalaea Bay and the Pailolo and Alenuihaha channels around Maui due to strong winds.
