With a low, rumbling roar, an arc of dirt, rock and mud swept down the hillside in the remote Mexican mountain village of La Pintada, sweeping houses in its path, burying half the hamlet and leaving 58 people missing in its mad race to the river bed below.
It was the biggest known tragedy caused by twin weekend storms that struck Mexico, creating floods and landslides across the nation and killing at least 97 people as of Thursday —- not counting those buried in La Pintada.
Every one of the nearly 400 surviving members of the village remember where they were at the moment the deadly wave struck on Monday afternoon, Mexico's Independence Day.
Nancy Gomez, 21, said Thursday that she heard a strange sound and went to look out the doorway of her family's house, her one-year-old baby clutched in her arms. She saw the ground move, then felt a jolt from behind as her father tried to push her to safety.
She never saw him again. He's among 58 missing in the slide or a second one that fell and buried victims and would-be rescuers alike.
When the rain-soaked hillside, drenched by days of rain during tropical storm Manuel, gave way, it swept Gomez in a wave of dirt that covered her entirely, leaving only a small air pocket between her and her baby.
"I screamed a lot, for them to come rescue me, but I never heard anything from my mother or father or my cousin," she said as she lay on a foam mattress in a temporary shelter in Acapulco, her legs covered with deep welts. Eventually, relatives came from a nearby house and dug her out.
The missing were not yet included in the official death toll: 81 who died across several states affected by the one-two punch of tropical storm Manuel and Hurricane Ingrid that both hit over the weekend. Some 35,000 homes were damaged or destroyed across the nation, according to Civil Protection officials.
Government photos show major mudslides and collapsed bridges on key highways, including the Highway of the Sun, a major four-lane expressway that links Acapulco to Mexico City. All the main arteries to the Pacific Coast resort town remained closed Thursday.
Manuel, the same storm that devastated Acapulco, gained hurricane force and rolled into the northern state of Sinaloa on Thursday before starting to weaken.
Sinaloa civil protection authorities said some areas were already flooding and more than 2,000 people were evacuated, many from small fishing villages on the coast.
And a tropical disturbance was moving toward Mexico's soggy Gulf coast even as the countries struggles to restore services and evacuate those stranded by flooding from Manuel and Ingrid, which hit the Gulf coast.
Interior Secretary Miguel Angel Osorio Chong told local media that conditions were still so unstable in La Pintada on Thursday, three days after the slide, that rescuers hadn't been able to recover any bodies yet. He said villagers told him they had buried at least five of their neighbours themselves before help finally started arriving.
So isolated is Acapulco that cargo ships have been contracted to supply food to the city by sea. Only about 10,000 of the estimated 40,000 stranded tourists have been flown out since the improvised air lift began two days ago.
Hundreds of stranded tourists remained lined up for a second day Thursday at an air base on the outskirts of Acapulco, where military aircraft were slowly ferrying people out of the resort.
Increasingly angry and frustrated by the long wait overnight and in the rain, they began to block army trucks heading into the base with what stranded travelers believed were wealthy, well-connected people or foreigners cutting line to get a flight out. The angry crowds forced the trucks to detour a few blocks along the beach to get to the base.
Mexican officials said that more than 10,000 people had been flown out of the city on about 100 flights by Wednesday evening, just part of the 40,000 to 60,000 tourists estimated to be stranded in the city.
But their pain was nothing compared to that of Amelia Saldana, 43, a single mother who lost her four boys — twins aged 5, another aged 7 and the eldest, 17 — in the landslide in La Pintada.
Saldana had gone down to town's main square for an Independence Day celebration, a rare time off for villagers who spent most of their days working in their coffee plantations. Because it was raining, Saldana told her sons to stay home while she went down to the square to get some of the free hominy stew being given away.
Then she heard the landslide, a low rumbling that villagers described as sounding like an earthquake. When she ran back to where her house once stood, it no longer existed.
"I tried to get back to my kids, but I couldn't" Saldana said between sobs. "I feel bad, because I lost everything."
