Flood Watch issued through Friday; storm to bring heavy rain and thunderstorms

Flood Advisory for East Maui until 12:45 p.m.

The National Weather Service issued a Flood Advisory for the East Maui area until 12:45 p.m. on Wednesday, April 8, 2026. At 9:34 a.m., radar showed heavy rain over East Maui with the heaviest rain upslope of Hāna, Hāmoa and Kīpahulu, falling at a rate of 1 to 2 inches per hour. Additional heavy showers will be possible into early afternoon. Some locations that will experience flooding include: Kīpahulu, Kaupō, Hāna, Hāmoa and Haleakalā National Park. This advisory may need to be extended beyond 12:45 p.m. if flooding persists.

Flood Watch through Friday afternoon

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.

The NWS reports that strong and gusty south to southeasterly winds are also expected Thursday and Friday. Unsettled conditions could continue through the weekend and next week as surface moisture and instability lingers.

With the ground saturated from recent storms, potential flash flooding, rapid runoff and landslide threats increase, even with less rain. 

The public should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
