An early-season cold front moving through Kauai and Oahu is forecast to stall near Maui County and slowly dissipate Sunday night through Tuesday. The potential for heavy rain began in the morning for the Garden Isle, and will move to Oahu in the afternoon and Maui County in the evening. Isolated thunderstorms will also be possible. Trade winds will briefly strengthen behind the front but will start to weaken again by early Monday.

Some drier air and more stable conditions are expected for Kauai and maybe Oahu Monday into Tuesday. Hawaii Island will remain mostly dry, but an area of tropical moisture is expected to move in from the southeast and bring some wet weather to windward and southeast portions of the island for the latter part of the week.

In surf, waves along north shores will ease as a northerly swell slowly declines into Monday, but a moderate sized north-northeast swell will push wave heights to just below advisory levels Monday night and Tuesday. Longer-term, a larger swell could bring another round of near-advisory level waves to north shores Friday. South shore waves will increase slightly Sunday with a small long-period south-southwest swell, while east shores will have small surf through the upcoming week due to a lack of strong upstream trade winds.
