A flood watch has been issued across the main Hawaiian Islands for the next few days as a trough moving over the state is anticipated to bring abundant tropical moisture with potential heavy rain, flash flooding and thunderstorms that may affect Kaua‘i as early as Monday night, Oct. 26.
According to the National Weather Service in Honolulu on Monday, that moisture is expected to remain nearly stationary for a few days, with the watch in place until Thursday, Oct. 29. The heavy showers may develop Tuesday morning, bringing intense rain rates.
The heaviest rain and thunderstorms are most likely Tuesday afternoon through Wednesday on Kaua‘i. If organized bands of storms develop, the National Weather Service in Honolulu says extreme rainfall rates are possible. Strong winds are not expected, but showers and thunderstorms could bring brief gusty winds.
Forecasters say it is still unclear which areas will see the heaviest rain, and the forecast may change over the next few days.
County, state, and federal officials continue to monitor the forecast and coordinate preparations. County services and facilities may close on little to no notice, depending on conditions.
“We’re watching this system closely with the National Weather Service and our partners, and the forecast could still change,” said Elton Ushio, Administrator of the Kauaʻi Emergency Management Agency. “Use the time before the rain arrives to get ready. Clear your gutters and drains, secure loose items around your home, and talk with your ʻohana about what you’ll do if the water comes up. Once the rain starts, stay out of rivers and streams.”
Residents still making repairs from Hurricane Lowell are encouraged to secure tarps, building materials, and debris that could be carried by floodwaters or block drainage.
