HONOLULU, Hawaii (HawaiiNewsNow) - A wet pattern is unfolding for Kauai and Oahu due to an out of season upper low and surface front positioned to the west-northwest.
Warm and humid conditions with increasing rain chances are anticipated through Tuesday as this upper low begins to drift toward the islands. Although the main threat for heavy rain will initially focus over the western end of the state, a gradual eastward shift down the island chain will become a possibility by midweek.
Winds will remain light out of the southeast, which will allow the land and sea breeze regime to continue.
A drying trend along with a return of a more typical trade wind pattern is not anticipated until late Thursday through the upcoming weekend.
Surf along all shores is expected to be below high surf advisory levels through the week, but odds are increasing that an advisory-level south swell will arrive next weekend.
A small short-period northeast swell will linger for the next couple of days before diminishing, while building trade winds next weekend will bring increasingly choppy surf to east facing shores.
