Hurricane Adrian grew into a major storm today in the Pacific off the southwestern coast of Mexico, with maximum winds now 130 mph, according to the U.S. National Hurricane Center.

Adrian, a Category 4 cyclone on the Saffir-Simpson hurricane scale, was 320 miles south of Manzanillo, Mexico, and moving west-northwest at 9 mph, the Miami-based agency said this afternoon.

“This general motion is expected to continue during the next two days keeping the hurricane away from the coast of Mexico,” center officials said in a bulletin. No watches or warnings are in effect for land.

Adrian is the first hurricane of the Eastern Pacific season and is forecast to dissipate early next week, according to the center’s tracking projections. A storm becomes a hurricane when winds reach 74 mph and becomes a major, or Category 3, storm at 111 mph.
