ACAPULCO, Mexico (CNN) -- Severe weather was hitting Mexico from nearly all sides Wednesday as Tropical Depression Manuel, the remnants of Tropical Storm Ingrid, and a new area of low pressure threatened most of the country with rain.
At least 57 lives had been lost due to the storms.
The hardest hit area was the Pacific state of Guerrero, where an estimated 40,000 tourists were stuck as dozens of roads were damaged and the airport in Acapulco temporarily suspended services.

Tropical Depression Manuel, which was off the west-central coast of Mexico, was responsible for the downpour on the Pacific coast. The storm could strengthen into a tropical storm on Wednesday as it takes a turn toward Baja California, the National Hurricane Center reported.
"The aid is flowing," Mexican President Enrique Pena Nieto told reporters. "A large deployment (of resources) is being made specifically to the most affected areas."
The severe weather made it difficult for aid to be airlifted into the hardest-hit areas, but were scheduled to resume Wednesday, he said.
While Manuel cast a shadow over the Pacific coast, a low pressure area on the Gulf side -- the remnants of Ingrid -- continued to threaten the coastal states of Tamaulipas and Veracruz.
And to the south, over the Yucatan Peninsula, another area of low pressure had a 70% chance of becoming a tropical cyclone within 48 hours, the National Hurricane Center said.
More than 1 million residents across Mexico have been affected in some way by the storms, Interior Minister Miguel Angel Osorio Chong told reporters.
Acapulco airport operator Centro Norte Airport Group moved its ticketing process to a convention center because of flooding in the passenger terminals.
Several airlines were waiving fees and helping get passengers out as the airport began to operate again.
Some 2,000 people had been flown from Acapulco to Mexico City as of Tuesday night.
The Acapulco city government said some 40,000 tourists were stranded in the resort destination. The government set up special hotlines to help tourists, and businesses were offering special discounts for those who found themselves stuck.
