A tornado that touched down in northern Colorado damaged several homes Thursday as storms brought flooding and marble-size hail to some areas.

At least three homes were destroyed in the town of Berthoud, about 40 miles north of Denver, said Lori Hodges, director of the Larimer County Office of Emergency Management. No injuries were reported.

Crews were checking on reports of about 25 other homes that were possibly damaged or destroyed, but they were hindered by foul weather and darkness.

"The rain is so heavy in that area with hail that they are not able to get more damage assessments," Hodges said.

Flooding has become a more immediate concern, she said, with pelting rain expected to continue into the night.

The Red Cross was responding to help people who have been displaced. Meanwhile, Boulder County sheriff's deputies were helping assess the damage and asking that people stay out of the area, Cmdr. Heidi Prentup said.

At least two other tornadoes touched down Thursday afternoon near the tiny town of Simla, about 60 miles southeast of Denver. Elbert County officials said at least five homes were damaged there.

No injuries were reported from that string of storms.

Forecasters had warned that the Front Range and the Eastern Plains could experience severe weather Thursday.
