US · Published Aug 21, 2026
Tropical Depression Two-C, expected to strengthen into Tropical Storm Moke, is forecast to impact the Big Island of Hawaii this weekend.
As of Thursday, the system had sustained winds of 35 mph and was located approximately 815 miles east-southeast of Hilo, moving north-northwest at 14 mph.

Impact & Risks

The southeastern parts of the Big Island, including Kaʻū and Puna districts, are at high risk of flooding and mudslides due to saturated grounds from previous storms. Heavy rainfall may lead to life-threatening conditions, especially in steep terrain. Strong winds localized by the island's terrain could cause additional damage to infrastructure and vegetation. High surf and rip currents pose significant risks to coastal areas. Residents in flood-prone areas and those with shoreline properties are advised to prepare for potential impacts, including power outages and road closures.
