Flood warning canceled for Oahu as rains ease

UPDATE: 11am

The flood warning for Oahu has been lifted.

Radar showed around 10:30 a.m. that heavy rain had eased over the island, the National Weather Service said.

A flood warning for Maui and the Big Island remains in effect until this afternoon.

“Deep tropical moisture associated with a low pressure trough will settle over the Kauai Channel today and dissipate by this evening,” forecasters said. “Combined with a temporary aloft disturbance, the threat of heavy rain, flash flooding and the possibility of some thunderstorms remains, particularly over windward portions of the Big Island and Maui.”

PREVIOUS COVERAGE

The National Weather Service has lifted the flash flood warning for the island of Hawaii as heavy rains eased this morning.

Weather officials are advising motorists that Highway 11 remains partially closed at Kawa Flats and traffic is limited to one lane due to previous flooding.

The flood watch for Maui and Hawaii continues until 6:00 p.m. today. The combination of persistent tropical moisture and an approaching cold front brings the possibility of additional precipitation and isolated thunderstorms, particularly in windward areas.

Residents and visitors are advised to remain cautious near streams and low lying areas as flood-prone roads may still experience runoff during the day. Drivers are asked to avoid flooded roads and exercise caution in partially closed areas.

Looking ahead, the National Weather Service predicts that a surface low and its accompanying plume of tropical moisture will put parts of the state at risk of heavy rainfall and isolated thunderstorms through today. Conditions are expected to improve as the low pressure dissipates by this evening, reducing the risk of significant downpours across most areas.

A cold front will approach the islands starting Wednesday and move partially through the state before stalling and dissipating Thursday. A new high pressure area to the north will result in a shift to wetter trade winds and windy to locally windy weather, which is expected to continue into the weekend.
