Authorities assessed the damage made by the massive tornado that struck the state of Colorado. The devastation area was of about 35 miles across northern Colorado, officials said.

One person was killed by the twister which hit on Thursday. The very high winds also wrecked at least 150 homes according to the estimations. There were some injured people as well. Thirteen of them were treated of their wounds in the state hospitals and nearly 100 other received medical attention at a Windsor community center, according to Jim Shires, a spokesman for emergency responders.

Rescue crews made use of their special trained dogs to look for victims under the rubble. They looked through Windsor three times and said they believe no one else is trapped.

"We've not been made aware of anyone missing at this point," Shires said.

The twister touched down in several towns of the Weld County on Thursday causing damages in its path. The powerful winds picked trucks off roads and even tipped 15 rail cars off the tracks in Windsor.

Windsor, situated about 70 miles north of Denver, was the town which suffered the most damage.

A meeting was held by civic leaders and emergency responders in Windsor’s Recreation Center this morning to talk about the disaster relief efforts. Colorado’s congressional delegation will ask for federal aid, according to U.S. Rep. Marilyn Musgrave.

"The senator and I, and Senator Salazar, will join us in sending a letter to the President of the United States asking for a designation that will allow federal dollars to go into this area," Musgrave said.

Anyone who has questions regarding the tornado relief is advised to call 1-970-686-2626, authorities informed.
