DENVER - Denver International Airport passengers took shelter after a tornado was spotted in the area.

The National Weather Service says a tornado was spotted in the area at 2:20 p.m. Tuesday, according to The Denver Post.

People took shelter in the airport's bathrooms, which double as shelters, and in stairwells. Television coverage showed the airport's normally busy concourse was completely empty.

A tornado warning was issued for northeastern Denver County and western Adams County, but expired at 2:45 p.m.

On Monday, a tornado touched down briefly in La Junta (lah-HUN'-tah) on Colorado's southeastern plains. No injuries were reported, but power poles were knocked down in an industrial park near town. Heavy rain fell Monday in La Junta and Lamar, where some streets flooded.
