The northern Colorado road leading to an area where two tornadoes touched down Thursday night was closed as crews check on downed power lines in the area.

Luke Koldewyn (COLD'-win) of Johnstown, who was waiting to get past a checkpoint, said his parents' modular home was destroyed in the twisters. He said his parents weren't home at the time but he waded in chest-deep water to check on their home, through a field that normally only has a small stream running through it.

He found only the house's deck was left standing and one of his parents' dogs, Luna, trapped in the rubble. "She didn't want to be free. She was scared to move," he said. Another black Lab named Juliet is missing.

He said residents are amazed that tornadoes touched down so close to the foothills, visible in the distance from the area of modest homes set on two- and three-acre plots.

"People who have lived here 50 years had never seen weather like that before," he said.
