Hurricane Sergio now Category 2

MEXICO CITY — Sergio, the 10th hurricane of the year in the eastern Pacific, strengthened into a Category 2 hurricane Wednesday as it drifted more than 400 miles off Mexico's coast.

U.S. National Hurricane Center forecaster Michelle Mainelli said the hurricane could strengthen further, but was expected to stay over water south of Manzanillo, Mexico, and moving southeast.

Mexico's Pacific coast has been blitzed with hurricanes and storms this year, while its Caribbean and Gulf of Mexico coasts have seen little activity.
