FORT LUPTON — What has been forecasted as a wild week of summer storms, Fort Lupton got the worst of what was in store for the Front Range Monday as a tornado touched down near U.S. 85 and Weld County Road 18.

Authorities spotted a funnel cloud near the North Station around 3:45 p.m., which prompted activation of the city’s tornado warning sirens.

Photographer John Carr said the storm appeared to touch down twice. He said the storm picked up “quite a debris field” from nearby farms as opposed to the normal rope tornadoes that tend to pick up nearby sources of moisture.

Weld County sheriff’s deputies received no reports of damage, and the warning expired around 4:15 p.m.

A second tornado touched down the same afternoon in southern Commerce City. It upended some soccer goals at Dick’s Sporting Goods Park and forced passengers at Denver International Airport to seek shelter.

The weather forecast for the rest of the week has called for heavy rain, and much of the state was under a flood watch with estimated precipitation between Tuesday and Wednesday ranging from 2 to 4 inches across the Denver metro areas.
