Manuel made landfall on the Pacific side while Ingrid, a category one hurricane, was expected to reach the coast on the Gulf of Mexico on Monday, but they had already swollen rivers, flooded streets and damaged bridges.
State-run energy firm Pemex evacuated three oil platforms off the Gulf coast of the northeastern state of Tamaulipas and shut down 24 wells, the company said on its Twitter account.
On the Pacific coast, Manuel was weakening after making landfall near the Colima state town of Manzanillo, packing top winds of almost 50 miles (85 kilometers) per hour as it moved northwest, the US hurricane center said in a 2100 GMT advisory.
The storms were blamed for at least 14 deaths in the southwestern state of Guerrero and six in the central states of Puebla and Hidalgo, officials said.
