Residents, especially those in windward and mauka areas, may want to keep umbrellas handy through Friday.
An earlier flood advisory for Oahu expired at 4:30 p.m.
Radar showed the rain moving westward and falling at a rate of about one inch per hour, according to the National Weather Service.
Forecasters expect an area of moisture to stall east of the islands, creating a greater chance of showers.
Tradewinds are expected to blow most of the rain clouds over windward and mauka areas, especially in the mornings. But some of the showers may make it over to leeward areas.
Forecasters say brief, heavy downpours are possible.
Drier conditions and breezy tradewinds are expected over the weekend.
A developing weather system may block the tradewinds early next week, creating more muggy weather and the chance of afternoon showers in leeward and mauka areas.
Out in the East Pacific, it’s still too early to say if what’s left of Tropical Storm Enrique and Hurricane Dolores will impact Hawaii’s weather other than sending some surf to east and north shores.
East shores should see a slight bump in surf heights from both systems.
Enrique was about 1,680 miles from Baja California Thursday and was expected to weaken into a remnant low by Friday.
Dolores also continued to weaken as it moved into cooler waters. It had maxium sustained winds of 105 miles Thursday and was moving west-northwest at 8 mph. The storm was 260 miles southwest of Cabo San Lucas, Mexico and was expected to become a tropical storm by Friday and a remnant low next week.
Typhoon Nangka in the far Northwest Pacific is also expected to bump surf up on northwest shores Friday into the weekend.
