MIAMI - Tropical Storm Carlotta has strengthened somewhat in the Pacific south of Mexico and is expected to become a hurricane.
Carlotta's maximum sustained winds rose Thursday to 50 mph (85 kph). The U.S. National Hurricane Center in Miami says further strengthening is forecast and Carlotta is expected to become a hurricane by the time it reaches Mexico's southern coast Friday.
A hurricane watch is in effect for Mexico's Pacific coast from Barra de Tonala to Punta Maldonado. The tropical storm was centered at 8 p.m. EDT Thursday about 275 miles (440 kilometers) south-southeast of Puerto Angel, Mexico, and about 490 miles (790 kilometers) southeast of Acapulco, Mexico.
It is moving north-northwest near 10 mph (17 kph). Tropical storm-force winds extend outward up to 45 miles (75 kilometers) from the storm's center.
