A cold front has moved through most of the islands and is currently near the Big Island. North to northeasterly winds are starting to build over most of the smaller islands to push out the vog and high humidity for those areas. This frontal boundary is forecast to stall near the Big Island (at least Edith Kanakaole Stadium is covered for Merrie Monarch!), and the returning trades will push some of the showers back over the windward and mauka areas through the weekend, although the wetter weather may linger over Maui and the Big Island during the first part of next week.
In surf, a new northwest swell is expected to peak Saturday, with a larger northwest swell expected to arrive Sunday night that could push wave heights to warning levels Monday and Monday night. For mariners, a Small Craft Advisory kicks in at 6 p.m. Friday for the Pailolo and Alenuihaha Channels and Maalaea Bay as the winds ramp up.
