Aurora Activates Tornado Sirens Without Official Warning

AURORA, Colo. (CBS4)- There is controversy surrounding the City of Aurora's decision to sound the tornado sirens on Sunday afternoon despite no official tornado warning.

Police told CBS4 that rotating storm clouds prompted the warning. The rotating clouds were spotted near 14th and Havana Street and Colfax Avenue and Potomac Street.

The National Weather Service in Boulder told CBS4 there was no tornado.

"We have a nation trained to look toward the National Weather Service for the official warning-- that wasn't there," said CBS4 Meteorologist Chris Spears. "An untrained eye may sometimes think they're seeing circulations that aren't of a tornadic nature and maybe more of a wind signature."
