Kihei, Hawaii – Flash flooding is already inundating roads and entering homes across parts of Maui tonight as intense tropical rainfall pours down at rates of 1.5 to 2 inches per hour, prompting urgent warnings across several Hawaiian islands.
According to the National Weather Service in Honolulu, a Flash Flood Warning remains in effect until 11 p.m. HST for the island of Maui, where radar shows the heaviest rainfall falling along the south-facing slopes and coast from Maalaea Bay through Kihei, Wailea, Makena, and Kipahulu. Law enforcement in Kihei has already reported multiple road closures and water entering homes.
Heavy rain bands are also producing flooding threats across Oahu, Molokai, and the Big Island, where separate flash flood warnings remain active through late tonight and early morning hours.
On the Big Island, rainfall rates of 2 to 3 inches per hour are hitting the Puna and Kau districts, including communities such as Pahoa, Volcano, Naalehu, Mountain View, and Hawaii Volcanoes National Park. Flooding in streams, roadways, and low-lying areas is expected, with landslides possible along steep slopes.
Across Oahu, emergency management officials report ongoing flooding issues across the entire island as heavy rain continues over already saturated ground.
Residents are urged to avoid streams, rivers, drainage channels, and flooded roads. Drivers should never attempt to cross water-covered roadways — turn around, don’t drown.
Warnings could be extended overnight if heavy rainfall persists, and additional flooding or landslides remain possible across Hawaii’s mountainous terrain.
