The surface low associated with the kona storm is now well to the north of the islands.
Several bands of moderate to heavy rain, with some embedded thunderstorms, continue to move slowly eastward across the islands this morning.

A 'wet trades' weather pattern will settle into the area on Tuesday and will continue through the weekend.
Forecast synopsis
From the National Weather Service office in Honolulu:
As of 3:19 AM HST on Sunday:
A surface kona low pressure system continues to meander northeastward away from the Hawaiian Islands, producing bands of moderate to heavy showers and embedded isolated thunderstorms across much of the state, namely Maui County and the Big Island. As the system exits the vicinity of the islands, a broad area of high pressure fills in its wake Monday, allowing trades to return from west to east, persisting through the remainder of the week. Windward showers will initially be scattered to numerous Monday, but will decrease to a more typical trade wind regime with isolated to scattered showers across windward and mauka areas.
Weather risk outlook
As of 3:00 PM HST on Saturday:
A full island-by-island risk outlook has not yet been produced.
