Maui is under a High Wind Warning through Sunday morning and a Flood Watch through Saturday afternoon.

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.

The Flash Flood Watch that was in effect for the Hawaiian Islands has since been cancelled. A Wind Warning continues for Maui County and the Big Island until 6 p.m. East winds of 25 to 35 mph are expected, with gusts up to 60 mph.

A new real-time dashboard launched by the University of Hawaiʻi at Mānoa offers public access to live weather data from nearly 70 monitoring stations across the state, marking a major milestone in the Hawaiʻi Mesonet project. The launch coincides with Wildfire Awareness Month and represents a pivotal moment in the effort to make climate data available to the public.
