Tropical Storm Greg forms off Mexico's Pacific Coast
Shortly after being upgraded from a tropical depression at 5 a.m. EDT, Greg was located about 260 miles (420km) south-southeast of Manzanillo, Mexico, the hurricane center said.
It was moving west-northwest at about 16 mph (26 kmh) on a course that was expected to keep it well off the Mexican coast. No coastal watches were in effect but heavy rains are possible for the Mexican states of Guerero and Michoacan, the hurricane center said.
