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.

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