Flash Flood Watch (Kohala Included)

UPDATE 8:00AM 10/12/2018

A flash flood watch is in effect for the state through Saturday evening as a storm system west of the islands moves eastward.

Forecasters with the National Weather Service in Honolulu said this morning that the system “will move from west to east across the area today through Saturday, bringing the potential for heavy rainfall and thunderstorms to the island chain.”

The potential for showers and thunderstorms is most likely this afternoon and evening for Kauai and Niihau, forecasters said. For Oahu to the Big Island, the threat continues until Saturday evening with “the most likely time frame for the heavy rainfall and potential flooding appears to be during the afternoon and evening hours both today and Saturday,” according to the weather service’s flash flood watch.

A watch means that conditions are favorable for flash flooding, which can be life-threatening, they warned, adding “do not cross fast-flowing water in your vehicle or on foot.”

”Remnant moisture” from the system “may combine to bring a wet and showery pattern to windward areas Monday through the middle of next week, with showers reaching leeward areas at times as well,” forecasters said.
