At least 110 people were confirmed dead as of Monday in the wake of Tropical Storms Manuel and Ingrid, according to Mexico's Interior Minister Miguel Angel Osorio Chong.
The extent of the damage remained unclear, but massive amounts of rainfall and flooding led Mexican President Enrique Pena Nieto to request that the Mexican congress provide more money for emergency relief.
"We are confronting rainfall that has practically been the most extensive in the history of the entire national territory," Nieto said on Sunday.
"Today we can already anticipate that due to the damages that we have seen, our funds are insufficient," he added.
More than 1 million people across Mexico have been affected by the storms, with around 50,000 forced to evacuate their homes, and about 20,000 living in shelters, according to the BBC.
Sixty-eight people were missing after a landslide swept away dozens of homes in the village of La Pintada in western Guerrero state. Rescue workers arrived on the scene to search for surivors. However, Nieto said there was very little hope that survivors would be found.
