Mexico ? Sergio strengthened into a Category 2 hurricane Wednesday, its winds increasing to 98 mph as it drifted far off Mexico’s Pacific coast.

Sergio, the 10th hurricane of the year in the eastern Pacific, was located 480 miles south of Manzanillo, Mexico, and was creeping southeastward at 2 mph, the U.S. National Hurricane Center in Miami said.

Center forecaster Michelle Mainelli said the hurricane could strengthen further, but was expected to stay over water, parallel to the Mexican coast, for the next five days.

The eastern Pacific hurricane season begins May 15 and ends Nov. 30.
