There had been no reports on injuries and the Fujita scale had yet to be determined to categorize the tornado, but the NWS reported that power poles and power lines were down near Highway 66 and County Road 21. 

Weld County Office of Emergency Management is working with local law enforcement to gather information on damages.

National Weather Service employees in North Longmont and Frederick captured photos of the funnel cloud as it tore across the landscape.
