Authorities in southern Mexico were still assessing damage and watching rising rivers as rain from the remnants of Hurricane Erick doused the region.

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.

Hurricane Erick, which rapidly intensified overnight, made landfall Thursday morning on Mexico's Pacific Coast as a powerful Category 3 storm, authorities said.
