Hurricane Erick slammed into Mexico’s Oaxaca state as a dangerous Category 3 storm Thursday morning, unleashing powerful winds at the coast and heavy rains that have caused deadly flooding in the region.

Authorities in southern Mexico Friday were still assessing damage and watching rising rivers as rain from the remnants of Hurricane Erick doused the region, with at least one death confirmed.

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.
