Heavy rain accompanied by thunder prompted a flash flood warning today for Oahu.
The warning was canceled shortly before 7:45 p.m., but the National Weather Service issued a flood advisory for Oahu until 10:45 p.m.
At 7:37 p.m., radar indicated heavy rain over the central Koolaus and central Oahu, the Weather Service said. Rain was falling at a rate of half an inch per hour and slowly moving westward.
Oahu appeared to take the brunt of the rains in the main Hawaiian islands due to unstable weather conditions in the northeast.
The weather is expected to be better Wednesday but some rain will continue, National Weather Service forecaster Norman Hui said tonight.
“Things should be settling down,” Hui said. “We still have the tradewinds.”
Close to 4 inches of rain fell over three hours in Manoa, according to the weather service’s report at 5:45 p.m.
The downpour created dangerous driving conditions during the afternoon commute on the Windward side of the H-3 Freeway and elsewhere, officials said.
Storm warnings were posted in the afternoon for Honolulu, Waimanalo, Haleiwa, Wahiawa, Schofield Barracks, Hawaii Kai, Ahuimanu, Punaluu, Wheeler Field, Waikele, Kalihi and Waiahole.
The most rain in 24 hours fell at a rain gauge in the Moanalua area — 4.58 inches, according to the weather service.
