HONOLULU (HawaiiNewsNow) - Trade winds will continue to trend lighter through Friday as the high pressure fan weakens north of the islands. Showers will continue to ride in with the trades, however shower activity will be limited. A cold front will bring a boost in showers on Sunday as it quickly moves down the island chain, with a quick burst of cooler, northerly air behind the front. High pressure to bring a return of drier than normal trade wind weather for next week.
Several reinforcing northwest swells will keep moderate sized surf in place along north facing shores through the remainder of the week. A gale force storm in the north Pacific will send a large swell towards the islands Thursday night into the weekend. This should lead to rapidly building surf out of the 330/340 degree direction on Sunday, with heights exceeding warning levels along north and west facing shores. Surf is expected to peak late Sunday afternoon or Sunday night at giant levels and steadily decrease Monday into Tuesday. High Surf Warnings (HSW) will likely be required for north and west facing shores of Niihau, Kauai, Oahu, Molokai and north facing shores of Maui and Big Island sometime later this week.
