Felica, which was once a Major Hurricane with 145 mph winds, has no weakened significantly down to tropical depression status; meanwhile, Guillermo, which was a strong tropical storm and impressive on satellite photography, has dissolved into a post tropical cyclone. While neither are expected to bring tropical storm or worse conditions to Hawaii, lingering moisture from these two systems could impact Hawaii weather in the coming days.
In the latest update from the National Hurricane Center, Tropical Depression Felicia was located roughly 1,075 miles east-southeast of Hilo, Hawaii. With maximum sustained winds of 35 mph, it was moving to the west-southwest at 16 mph. The National Hurricane Center expects additional weakening, with Felicia becoming a remnant low by tomorrow.
Guillermo has weakened even more than Felicia, becoming a post-tropical remnant low. Located about 1,110 miles west-southwest of the southern tip of Baja California, the system still had some winds of 35 mph while it was moving west at 17 mph. The National Hurricane Center says Guillermo will continue to weaken, completely dissipating later this week.
While these systems won’t impact Hawaii as a tropical cyclone, some of their leftover moisture could. The American GFS forecast model suggests some moisture associated with Felicia could impact Hawaii and Maui islands as early as Friday, with even more moisture from Guillermo arriving on Monday. While strong winds won’t be an issue, heavy tropical downpours could become problematic, especially over the eastern portions of the islands where the leftover moisture could hit.
