Heavy rain for the last several weeks has led to mudslides throughout southern Mexico. The death toll currently stands at 32.
Officials say that Mexico had three consecutive weeks of intense rain from what was left of a hurricane and then a tropical storm.
Oaxaca state's Civil Protection operations coordinator, Luis Marin, said the state had seen three days straight of intense rain. The state government warned residents south of the city of Oaxaca of flooding from overflowing rivers and opened shelters in other parts of the state.
More than 810,000 people have lost their homes because of the mudslides and flooding.
Some of the slides have occurred in some of the remotest mountain towns in Mexico, and search crews have had to travel long distances to reach the slide areas.
It's the annual rainy season in Mexico, and officials have reported it is the wettest on record.
