The National Weather Service in Honolulu has extended the flash flood warning for Oahu until 4:15 a.m. A breezy and drier trade wind weather pattern will spread over all islands by Thursday, continuing into the weekend,” the weather service said “A drier airmass moving in from the east has begun to reach the Big Island and Maui, but a few heavy showers are possible over Maui County this morning. The forecast for the entire state calls for the kona low northwest of the islands to drift away from the area on Wednesday. Additional heavy rainfall on Oahu could cause severe flooding impacts, as six to ten inches of rain has fallen over the entire island since Monday.”įorecaster say heavy rain will continue across Oahu and Kauai County as a kona low pulls deep tropical moisture over the western end of the island chain, bringing the threat of heavy rain and a few thunderstorms with gusty winds. Numerous landslides are expected in areas with steep terrain. Debris in streams and gulches may clog bridges and culverts resulting in dangerous flooding. “Low spots in roads will become dangerous and impassable due to severe runoff. “Rain events of this size can cause catastrophic flooding and affect areas that do not usually flood,” the weather service says.
The National Weather Service in Honolulu says flash flooding caused by excessive rainfall remains possible on Kauai, Niihau and Oahu.
The flash flood warning for Oahu has expired but the island and Kauai County remain under a flood watch through Tuesday afternoon. EDITOR’S NOTE: See today’s story for the latest weather updates.
