Some people in the low-lying working class neighborhoods of Poza Rica heard the wall of water before they saw it.

The loudest sound was from the cars crashing together as they were swept along by the water that had escaped from the banks of the Cazones River and flooded the streets with more than 12 feet (4 meters) of water at dawn Friday.

On Saturday, much of that water had flowed away.

What was left was pure destruction and the sometimes head-scratching combinations made when nature collides with the man-made: like cars hung in treetops and even a dead horse wedged inside the cabin of a pickup truck.

The death toll from landslides and floods set off by incessant rainfall in central and southeastern Mexico rose to 41 people on Saturday, authorities said, a sharp increase as thousands of soldiers cleared blocked roads to rescue the missing.

In Poza Rica, an oil town 170 miles (275 kms) northeast of Mexico City, there was little warning before the water arrived.

Some residents said they sensed danger a couple of hours earlier and grabbed a few belongings before abandoning their homes.
