Hawaii Monitors Tropical Threat with 90% Development Chance
US · Published Aug 20, 2026
Hawaii is on alert as a tropical disturbance east-southeast of the islands shows a 90% chance of developing into a tropical depression within 48 hours, according to the National Hurricane Center (NHC) on August 19,
The system, which could be named Moke if it strengthens, is expected to bring tropical moisture and rain to the region. While most forecast models predict the storm will pass south of Hawaii, some suggest a closer approach to the Big Island, raising concerns for areas still recovering from Hurricane Lala. The NHC is also monitoring another disturbance farther east with an 80% chance of development over the next seven days.

Impact & Risks

The potential storm poses risks of heavy rainfall and tropical storm conditions, particularly for the Big Island, which is still recovering from Hurricane Lala. Over 100 homes were damaged or destroyed during Lala, and approximately 20,000 residents remain without power. Additional rainfall could exacerbate recovery efforts and increase the risk of flash flooding. Surf conditions may also be affected depending on the storm's size and proximity to the islands.
