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.

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.

The storm was downgraded slightly before making landfall, from a powerful Category 4 to a Category 3. While slightly reduced in power, Erick is still considered a major hurricane as a Category 3, which can carry winds of up to 129 mph (210 kph).
