Rivers spilled their banks, sweeping people from their houses and burying others under mud and boulders; according to the governor of the southern state of Oaxaca.

According to the governor of the southern state of Oaxaca; Hurricane Agatha brought flooding and mudslides that killed at least 11 people and left 20 more missing.

Rivers burst their banks, sweeping residents from their houses, while others were buried under mud and rocks, according to Governor Alejando Murat.

Murat told local media that there were “basically two explanations” for the fatalities. “On the one hand, there were overflowing rivers, and on the other hand, the most important part, there were landslides.”

In May, during the eastern Pacific hurricane season, Agatha made history as the fiercest storm ever recorded to hit land.
