9:45 a.m.

The flood advisory for Oahu has been canceled.

The National Weather Service says, “Spotty, hit-or-miss heavy downpours will continue to be possible over the next couple of days.”

The state will be under a flood watch from Wednesday until at least Friday. “A late-season kona low will develop several hundred miles north of the islands Tuesday night, and then meander around well northwest of the islands the rest of the week,” forecasters said.

“The kona low will turn our winds southerly as early as Tuesday, and eventually tap into deep tropical moisture lurking south of the islands. This will cause a slow-moving band of showers, some heavy, and a few embedded thunderstorms over some parts of the state for the second half of the week. Excessive rainfall and flash flooding will continue to be a concern.”

A flood advisory remains in effect for Oahu and a flood watch will be in effect for the entire state from Wednesday through at least Friday.

The flood advisory is in effect through 8 a.m. today for Oahu due to continued flooding caused by excessive rainfall.

Radar at 6:16 a.m. showed moderate showers moving north at 5 mph with the heaviest rain over East Oahu, according to the National Weather Service. More showers are possible over the next few hours.

Some locations that could experience flooding during the morning rush hour include Honolulu, Hawaii Kai, Waipio, Moanalua, Kalihi, Salt Lake, Halawa, Aiea, Pearl City, Manoa, Kaneohe, Maunawili, Waipahu, Kapolei, Waimanalo and Kailua.

The flood watch is in effect from Wednesday morning through Friday evening.

“Roads in several areas may be closed, along with property damage in urban or low-lying spots due to runoff,” the NWS said in a bulletin this morning. “Landslides may also occur in areas with steep terrain.”

A kona low developing north of the islands will bring the possibility of heavy rain and thunderstorms over parts of the state from Wednesday through Friday and possibly continuing through the weekend, weather officials said. Oahu and Maui County are likely to experience heavy rainfall later on Wednesday and into the night. The weather system is expected to gradually move westward, with Kauai becoming the main area of concern by Friday.
