MEXICO CITY - The first tropical depression of the Pacific hurricane season has formed off the coast of Mexico.
The National Hurricane Center in Miami said the depression was centered about 360 miles (575 kilometers) south-southwest of the Mexican city of Mazatlan on Thursday afternoon.
Maximum sustained winds are near 35 mph (55 kph). Forecasters say the depression could strengthen to a tropical storm with wind speeds of 39 mph or more, before it nears the Mexican coast by Friday night or Saturday.
The depression was moving toward the north at about 7 mph (11 kph) and was expected to turn gradually north-northeast late Friday.
Mexican authorities have issued a tropical storm watch for the Pacific coast from Topolobampo south to El Roblito and for the Islas Marias.
