Gusty trade winds will continue to blow over the islands Sunday, with some gusts near 50 miles per hour still possible in some areas. A wind advisory has been extended to most areas of the islands through 6 p.m.
An old cold front has brought some cooler and wetter weather, especially for windward and mountain areas. The cloud band associated with the front is pretty much clearing Kauai and Oahu, with more clouds and showers still possible for Maui County and the Big Island. The trade winds will ease up a bit, but it should remain on the breezy side with frequent windward and mauka showers for the next several days.
An upper trough is parked to the west, bringing a flow of mid- and upper-level clouds over the islands from the southwest that will likely last through Monday. We’re not expecting rain from these clouds, but it will filter the sunshine a bit and keep the daytime temperatures down.
Longer term, the forecast is looking at another upper trough to drop in over the islands near the end of the week, which would increase rainfall coverage and intensity.
At the beach, a high surf warning is now posted for the north shores of Molokai, Maui and the Big Island, with high surf advisories for north and east shores of Kauai, Niihau and Oahu and the east shores of Molokai, Maui and the Big Island. The large long-period north swell is expected to peak late Sunday while strong trades will bring rising surf for east shores. Eastern shores with a northern exposure could also see higher surf as well. A small craft advisory remains posted over all Hawaiian coastal waters due to the high seas and strong winds.
