Tropical Storm Guillermo formed in the East Pacific and is expected to strengthen into a hurricane before weakening as it approaches Hawaii next week.
At 5 a.m. Thursday, Guillermo was 1,505 miles southwest of Baja California, or about 1,980 miles east-southeast of Hilo, moving west-northwest at 15 mph with maximum sustained winds of 40 mph.
The storm’s five-day track has it entering the Central Pacific as a hurricane by the weekend, but it should begin to weaken to a tropical storm as it approaches Hawaii.
Forecasters at the National Weather Service in Honolulu said, “The weather over the main Hawaiian islands next week will depend on the progress of this tropical system.
“The global models currently show the system passing northeast of the main Hawaiian islands through the middle of next week. That would likely bring light winds and muggy weather to the islands,” they said, but added, “however, it is too soon to know exactly what the disturbance will do.”
Closer to Hawaii but weakening is Tropical Depression Eight-E, which is expected to enter the Central Pacific Thursday but dissipate into a remnant low as it passes the islands this weekend..
“Expect humid weather to spread across the islands as well as possible increased showers for windward areas, especially the Big Island over the weekend,” Honolulu forecasters said..
