Honolulu set a new rainfall record for March 10 of 1.67 inches at the airport, beating the old record of 1.65 inches that stood since 1951, the National Weather Service reported.
Forecasters say lingering moisture and unstable conditions in the atmosphere means the threat of rain, even thunderstorms remains in the state-wide forecast.
Honolulu can expect partly sunny to mostly cloudy skies with scattered showers. A new weather system is expected to move in over the weekend, bringing the possibility of more wet weather to the islands.
Winds will shift and become southerly ahead of the front, meaning muggy and voggy Kona weather will return on Thursday.
A high-surf advisory ended at 6 p.m. Monday for the north and west shores of Niihau, Kauai and Molokai and the north shores of Oahu and Maui as a northwest swell faded.
The rains Saturday night and Sunday prompted flood advisories for Oahu and Molokai.
In the 24-hour period ending at 2 p.m. Sunday, 3.6 inches fell at Honouliuli and Waihee; about 3.4 inches fell on Ahuimanu; and nearly 3 inches was recorded at Kalaeloa.
The rainy weather may have contributed to a landslide that closed one westbound lane of Mokapu Boulevard in Kailua late Sunday afternoon.
No injuries were reported.
Also Sunday, the state Department of Health’s Clean Water Branch issued a brown-water advisory for Oahu after heavy rains resulted in storm-water runoff entering coastal waters.
