Hurricane Erick had strengthened to a Category 4 storm as it approached the coast but weakened to a Category 2 storm before making landfall on Thursday.

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.

A 1-year-old baby boy is the first confirmed death from Hurricane Erick, after the category 3 hurricane made landfall on the southwestern coast of Mexico Thursday morning.
