Hurricane Julio strengthens to category 2: U.S. NHC
Julio, which was moving west-northwest at about 17 mph (28 km/h), could continue to strengthen on Thursday but was forecast to gradually weaken on Thursday evening and continue into the weekend, the center said.
Julio was upgraded on Wednesday from a tropical storm and has been forecast to roll into the island chain of Hawaii as early as Saturday.
