MIAMI » Hurricane Dolores was beginning to develop an eye as it strengthened off Mexico’s southwest coast Tuesday evening.

The hurricane’s maximum sustained winds increased slightly to near 85 mph. The U.S. National Hurricane Center said Dolores was expected to become a major hurricane Wednesday.

The storm was centered about 250 miles southwest of Cabo Corrientes, Mexico, and moving west-northwest near 7 mph.

Swells generated by Dolores were affecting parts of the southwestern Mexican coast and were expected to affect the southern coast of Baja California later Tuesday. The hurricane center said the swells could cause life-threatening surf and rip currents.

Another system, Tropical Storm Enrique strengthened a little but stayed far out in the Pacific, about 1,365 miles west of the southern tip of Baja California.

Enrique had maximum sustained winds of 50 mph and was moving west-northwest near 9 mph. It was expected to weaken in the next day or two.

In the Atlantic, Tropical Storm Claudette was expected to weaken further overnight and dissipate Wednesday. Claudette’s maximum sustained winds were 45 mph.

Claudette was centered about 240 miles south of Halifax, Nova Scotia, and moving northeast near 21 mph.
