HNN issues First Alert Weather Day for Oahu, Kauai ahead of more heavy showers

HONOLULU (HawaiiNewsNow) – Another round of heavy rainfall is expected for the state this weekend. Given the ongoing threat of flooding, Hawaii News Now has issued a First Alert Weather Day for Kauai and Oahu starting Saturday night through Sunday.

The heavy rains are expected to start on Kauai on Saturday night.

Oahu and Maui County will see heavy rain Sunday afternoon into Monday. The Big Island will see the least rainfall out of the island chain, with the peak occurring Monday night into Tuesday.

Flooding rains batter Kauai, triggering rescues and closing all the island’s public schools

Flooding will be the main concern with this storm system, especially for Kauai.

The ground and soil of the Garden Isle is already saturated and it won’t take much rainfall for flooding to occur again. Flood watches may be issued by the National Weather Service.

Thunderstorms are less likely in this storm system.

There is less instability present in the atmosphere, leading to a lower chance for lightning and severe weather. However, these hazards cannot be completely ruled out.
