MIAMI — Vance has become a hurricane as it churns off the coast of Mexico, the National Hurricane Center said early Friday. At 0900 GMT, Vance was a Category 1 hurricane with maximum sustained winds of 85 m.p.h. (140 km/h), and was about 440 miles (710 kilometres) south-southwest of Acapulco. Vance is moving toward the north-northwest near 6 m.p.h. (9 km/h), and this motion is expected to continue through the weekend. The centre said the storm is expected to strengthen rapidly and could be a major Category 3 hurricane before the end of the day. The Associated Press
