A new Kona low system has arrived on Kaua‘i this afternoon, bringing rain and dark clouds. All Hawaiian Islands are under a flood watch through Sunday afternoon.
Derek Wroe, meteorologist for the National Weather Service in Honolulu, said the storm is moving west to east and will primarily concentrate over O‘ahu and Maui Counties.
Wroe said flood risk is relatively low on the Garden Island, but it’s not zero as heavy rain in the mountains can produce large amounts of runoff to streams and rivers.
There will be a lull in showers Friday, but Wroe said rain will redevelop on Saturday.
Kaua‘i County crews and personnel are on standby should a need arise due to severe weather. Officials are asking the public to remain vigilant.
All county roadways are open. However, with the potential for flooding, flood-prone roads and other low-lying areas may be closed due to elevated runoff and overflowing streams.
The Hawai‘i State Department of Health advises beach users to stay out of the water when the water appears brown or murky, especially following storms or heavy rain.
The public is advised to check conditions before venturing out for hiking, river, or beach excursions. River and stream crossings, recreational trails, and other outdoor recreation areas may quickly become hazardous.
During severe weather, emergency rescues may not be possible. Do not cross swollen rivers or streams; always check with a lifeguard at any lifeguard station before entering the ocean.
