HONOLULU, Hawaii (HawaiiNewsNow) - Trade winds will weaken into Tuesday and showers will become more active as an upper-level low develops just west of the state.

Trade winds will strengthen Tuesday night and Wednesday as the upper low sends thick high clouds overhead.

The weakening upper level low will slowly move over the state late Thursday into the weekend, bringing potentially wet and unsettled weather. The greatest potential for increased showers and unsettled conditions statewide looks to be Thursday night and Friday when the weakening upper-level low drifts over the islands.

Surf will remain well below high surf advisory levels along all shores this week.

The current northwest swell is slowly declining.

Surf along east-facing shores will diminish through Tuesday as the trade winds slacken, but will rebuild Wednesday and Thursday as winds increase again.

Low background southern hemisphere swell energy will maintain small south shore surf through the week. Some additional south-southwest swell energy arriving in a couple of days will provide a minor boost to south shore surf.
