Forecasters had expected up to 40 centimeters (16 inches) of rain could fall across Oaxaca and Guerrero, with lesser totals in Chiapas, Michoacan, Colima and Jalisco states. The rainfall threatened flooding and mudslides, especially in areas with steep terrain.

Erick was expected to reach hurricane strength as it neared land Wednesday. The cyclone was centered about 180 miles (290 kilometers) south-southeast of Puerto Ángel, Mexico, at 3 a.m. CST (0800 GMT), according to the U.S. National Hurricane Center.

Erick weakened to a tropical storm after making landfall as a major hurricane on Mexico's southern Pacific coast on Thursday, leaving flooded streets, damaged boats and buildings in Oaxaca as authorities warned of dangerous rains.
