The storm threatened to unleash destructive winds near where the eye crashes ashore, flash floods and a dangerous storm surge, forecasters said.

The hurricane had been a Category 4 storm as it bore down from the eastern Pacific toward Mexico. The authorities ordered evacuations in Oaxaca and Guerrero.

Hurricane Erick slammed into Mexico’s Oaxaca state as a dangerous Category 3 storm Thursday morning, unleashing powerful winds at the coast while spreading heavy rain over the region.
