The two children were identified as Charlotte Trotter, 4, and Sebastian Trotter, 7, according to their aunt Tiffanie Wyatt. She said their father, Sebastian Trotter, a solder based at Fort Bliss in El Paso, Texas, and their mother, Stephanie, both suffered serious injuries but survived and were receiving medical treatment at a hospital in Texas.

Flash flooding from torrential rain killed at least three people Tuesday afternoon and prompted dozens of rescues in the Ruidoso area of southern New Mexico, officials said — the same area devastated by two wildfires last year. A house was seen being carried downstream by the fast-moving water.

The neighbouring state of Texas also experienced a major flood just a few days earlier, but with a very different outcome. The ferocity of the inundation in Texas caught forecasters and state officials by surprise, killing at least 120 people.

At least three people were killed by historic flash floods in a New Mexico mountain community that suffered devastating wildfires last year, officials said late Tuesday.

"The main reason was the South Fork Fire last year that burned directly west of Ruidoso," Grzywacz said. "The soil wasn't able to absorb any of the rainfall, and it runs right down into Ruidoso. Normally, if you had that vegetation still there, it could absorb it. For the Ruidoso monsoon season, it was above average rain but not record rainfall."

Crews are working to clear twisted metal, broken trees and muddy debris from streets and homes a day after monsoon rains triggered a deadly flash flood in southern New Mexico.

Monsoon rains over burn scar areas from last year's fires caused devastating flash floods in New Mexico, killing three people and prompting water rescues.

Mexico has sent water rescue teams and firefighters to help in Texas after the holiday weekend floods that have killed at least 100 people, with many more still missing.
