A flash flood warning for Kauai expired at 2:30 p.m. Wednesday.

At 11:24 a.m., the rain was nearly stationary over Hanalei.

Forecasters say more heavy rain is possible Wednesday afternoon along with near-record temperatures, vog and humid conditions.

The National Weather Service said unstable atmospheric conditions, light winds and moist air over the islands will linger until Thursday, when tradewinds return.

Honolulu and Hilo tied high temperature records Tuesday. The 91-degree high recorded at the Honolulu Airport tied a record set in 2004. Hilo’s high of 88 degrees tied a record set in 1974.

Forecasters say Wednesday will also be hot, with highs of between 84 to 90 degrees expected, but clouds over Kauai and Oahu could keep the high temperature below record levels on those islands.

Haze from Kilauea volcano may also move over the western islands.

Heavy rains fell on Oahu Wednesday morning, with more than 2.8 inches recorded in Nuuanu and 2.7 inches in Manoa in the 24-hour period ending at 8 a.m. A flood advisory for Oahu expired just before 8:30 a.m. as heavy rain that started just after 5 a.m. eased.

Forecasters also put out a marine advisory Wednesday morning because of the possibility of waterspouts south of Kauai.

More heavy rains are possible Wednesday afternoon, including a slight chance of thunderstorms on Kauai and the Big Island, as sea breezes cause clouds to build up over leeward and mauka sections of the islands.

A high surf advisory is in effect through 6 p.m. Wednesday as forecasters expect a swell created by winds in the East Pacfic and former Tropical Storm Enrique to push surf to 5 to 8 feet along east-facing shores.

South shores may also see a boost starting Friday and peaking Saturday with near-advisory or advisory level surf.

The light winds, potential for rain and muggy weather are likely to continue until Thursday evening when cooling tradewinds slowly return. Rains Thursday are not likely to be as heavy as the showers Tuesday and Wednesday, forecasters said.

The cool respite will be brief, however.

Remnants of what was once Tropical Storm Enrique are expected to move over or near the islands this weekend, bringing more muggy, wet weather and possibly cutting off the tradewinds again.
