Report of a small tornado in south Alliance. Picture taken at 8th and Dakota looking south.
An apparent tornado has damaged a house and derailed rail cars in Alliance.
Law enforcement officials reported to the National Weather Service that the tornado touched down about 5 p.m. Friday.
KCOW reports that a roof was ripped off an Alliance home and thrown into the porch of an adjacent house. Six coal cars were thrown off the tracks at a Burlington Northern Santa Fe rail yard in south Alliance.
KCOW says sirens blew in Alliance and Hemingford as eye witnesses viewed the storm that entered Alliance from the south.
Weather spotters from Hemingford also viewed small twisters west of their community that briefly touched down.
KCOW says the NWS in Cheyenne did not issue an official warning.
In a phone interview Saturday Alliance Police Chief John Kiss tells 10/11 it was an unusual weather event on Friday afternoon, "We've had tornado warning's in the past but most of the time you see them coming from Wyoming or Colorado."
He goes on to say, "I think it's going to be a good lesson for people because instead of heeding the tornado warning sirens a lot of people because there was no anticipation of the storm, instead of going to their basements, ended up coming out on the streets to see what was going on."
Kiss adds the storm knocked down power lines, tore shingles off roofs in Alliance, but luckily no one was hurt.
The NWS in Cheyenne tells 10/11 officials have not confirmed a tornado in Alliance. They will send crews to investigate Saturday afternoon. They say it's possible the damage was due to weak rotation or straight line winds.
