Hurricane Roslyn forecast to bring dangerous storm surge to Mexico

Hurricane Roslyn was expected to deliver a treacherous storm surge to parts of Mexico Sunday after plowing over the Pacific as a powerful Category 4 storm just offshore from the resort of Puerto Vallarta.

The U.S. National Hurricane Center said early Sunday that Roslyn had become "extremely dangerous" with maximum sustained winds of 130 mph.

The storm was forecast "to bring damaging winds, a life-threatening storm surge and flooding rains to portions of west-central Mexico today," the hurricane center said at 12 a.m. Sunday.
