Hurricane Dolores is rapidly strengthening to a category 4 hurricane off Mexico’s Pacific coast, with maximum sustained winds increasing to near 130 mph (209 kph), the U.S. National Hurricane Center said on Wednesday. The storm, now at the second-highest hurricane classification category, was about 320 miles south of Cabo San Lucas, Mexico, and moving west-northwest at 7 mph.

Swells generated by Dolores are affecting portions of the coast of southwestern Mexico and the southern coast of the Baja California peninsula, the NHC said. These swells could cause life-threatening surf and rip current conditions, it said. MORE
