Hurricane Nolo Threatens Hawaii With Catastrophic Floods
US · Published Sep 23, 2026
• Hawaii is bracing for significant impacts as a tropical depression south of the islands is expected to intensify into Hurricane Nolo by September 24,
• Heavy rainfall is forecast to begin on September 23, potentially leading to catastrophic flooding and mudslides, especially in areas recovering from Hurricane Lala. As of 5 a.m. HST on September 23, the storm was located 320 miles south-southeast of South Point, Hawaii, with sustained winds of 35 mph. The system is predicted to turn northward, bringing life-threatening surf and rip currents to the region. Rainfall totals could exceed 20 inches in higher elevations, with widespread impacts across the Big Island and eastern Maui. A flood watch is in effect for several islands, including Maui and Molokai, through September 26.

Impact & Risks

The eastern Hawaiian Islands, particularly the Big Island, face severe risks from heavy rainfall, flooding, and mudslides. Areas recovering from Hurricane Lala are especially vulnerable. Rainfall rates, rather than totals, are expected to drive significant impacts, with over a foot of rain possible in steep terrain. Coastal areas will experience dangerous surf and rip currents, while wind and wave impacts may increase regardless of the storm's exact track. Property damage, landslides, and disruptions to local events, such as the cancellation of the Na Wahine O Ke Kai canoe race, are anticipated.
