HONOLULU (HawaiiNewsNow) - Slow-moving heavy showers made for a very wet Sunday for much of Oahu, which was under a flood advisory for much of the evening.

Rain was falling at a rate of one to two inches per hour over parts of the island during the heaviest rainfall.

The heaviest showers were in Central Oahu, where the Poamoho rain gauge recorded 3.11 inches in the 24-hour period that ended at 10 p.m. Mililani wasnʻt far behind with 3.08 inches. Wheeler Army Air Field picked up 2.53 inches of rain during the same time period.

The heavy rain is the result of light winds and an upper level trough moving over the islands. Enhanced showers with locally heavy rain is possible through Monday statewide. The low should move east of the state Tuesday, allowing more stable trade wind weather to return.
