Tourists trapped in flood-stricken Acapulco for almost a week packed into cars and buses on Friday after authorities reopened the road link to Mexico City following deadly storms.

The good news for increasingly angry beachgoers contrasted with the grim search for scores of people missing in nearby mountains after a massive mudslide swallowed half of their village.

While rescuers dug through mud in La Pintada, authorities were searching for a police helicopter that disappeared while conducting relief missions in the same mountain region of southwestern Guerrero state.

Mexico was hammered by the one-two punch of tropical storms Ingrid and Manuel, which left a trail of destruction that damaged tens of thousands of homes, flooded cities and killed around 100 people.

After regenerating into a hurricane and hitting the northwestern state of Sinaloa late Thursday, affecting 100,000 people and killing three, Manuel finally dissipated over the mountains.

The state of Guerrero was the hardest hit, with at least 65 deaths and its Pacific resort of Acapulco left isolated after the two roads to Mexico City were covered in landslides on Sunday.

Thank God we're leaving

Traffic piled up in Acapulco as police allowed cars to leave in groups of 50 to avoid huge backups on the "Sun Highway."

The highway department warned travelers that the trip north, which usually takes around four hours, would last nine to 10 hours, with only a single lane open in some stretches.

"Thank God we're leaving, even if there is traffic," said Imelda Cuellar Ramirez, a Mexican holidaymaker who was driving out with eight relatives.

More than 40,000 tourists, mostly Mexicans seeking sun during a three-day holiday weekend, were left stranded when the storms struck five days ago.

Half the city was flooded, while rising waters brought out crocodiles. Looters ransacked stores.

Around 24,000 tourists were able to leave in airlifts organized by the military and commercial carriers, but tempers flared as they stood in long lines to get one of the precious seats.

Thousands of frustrated tourists sheltered at the convention center blocked an avenue for half an hour late Thursday in protest against the slow pace of the airlift.

Waiting to board a bus, Alejandro Tubias, a Mexico City resident, said it was high time to leave after his wife contracted a stomach bug that they blamed on the lack of drinking water.

"We are more than happy. We are in a hurry to go because my wife is sick and because we don't have any money to pay the hotel room," he said.

Many dead

While tourists drove out of Acapulco, hundreds of troops and civil protection workers dug with shovels and pickaxes in La Pintada, a coffee-growing village west of Acapulco swamped by a massive mudslide.

Authorities say 68 people have been reported missing and two bodies were pulled out for now, but villagers fear that scores have perished.

"I think there's a lot of dead. A lot of my relatives died, they're buried and we can't do anything," said farmer Diego Zeron.

The mud collapsed on the village of 400 people during independence day celebrations last Monday, swallowing homes, the school and church before crashing into the river.

The soldiers and civil protection workers, many wearing surgical masks, removed pieces of broken homes and chopped up fallen trees with machetes.

Helicopters evacuated more than 330 villagers to Acapulco, but a few families decided to stay back, waiting for news on the missing.

A police helicopter that had been flying relief missions in the same mountain region in Guerrero state disappeared overnight after authorities lost contact with the crew.

A defense ministry spokesman said military helicopters have been dispatched on a search mission but cloudy weather in the mountains is "limiting the flights."
