A Flood Watch is in effect for the entire state through Friday afternoon. The National Weather Service reports that low pressure developing west of the islands will draw abundant moisture northward as it strengthens during the next couple of days. This will bring potential for heavy rain and thunderstorms leading to flash flooding over all Hawaiian islands.

Increased moisture will bring periods of heavy rain and a risk of flash flooding to the entire state by the end of this week and possibly into the weekend, with the most likely period of significant impacts during a period from Wednesday night, April 8, through early Friday, April 10.

The risk for flash flooding will begin today for Kauaʻi, tonight for Oʻahu, Wednesday for Maui County, and Wednesday night for Hawaiʻi Island. The potential for strong to severe thunderstorms and damaging southerly winds is expected to increase significantly statewide late in the week and into the weekend.

A powerful kona storm will begin impacting the western end of the state as early as Tuesday, then spread across the remainder of the island chain by midweek.

“A strong low pressure system will bring deep moisture over the state, leading to the potential for heavy rain, flash flooding and thunderstorms,” according to the NWS. “The threat for flash flooding could develop over Kaua’i County late Monday, spreading eastward to the entire state Tuesday and Wednesday, and persisting through the rest of the week.”

A Flash Flood Warning is canceled for the island of Maui as of 1:54 p.m. on Tuesday, Jan. 9, 2024. The National Weather Service reports that heavy rain on Maui has ended, and flooding is no longer expected to pose a threat. A Flood Watch remains in effect until 6 p.m. for Kahoʻolawe, Lānaʻi, Maui, Molokaʻi, and the Big Island of Hawaiʻi.

The County of Maui is now taking steps to prepare as an approaching Kona low storm system brings the potential for damaging conditions.

Trade wind weather today will gradually transition over to a more unsettled pattern on Tuesday across the western islands and across the entire state from Wednesday through Friday as a kona low matures and gradually breaks down to the west of the island chain, according to the National Weather Service.
