WELD COUNTY, Colo. (KDVR) — Investigators with the National Weather Service flocked to Weld County to get an up-close idea of the size and scope of the landspout tornado that ripped up land from Frederick to Platteville.

The NWS officially rated the tornado as an EF1.

Initial measurements indicate the landspout tornado traveled roughly six miles, with wind speeds up to 99 miles per hour.

“The more I watched it. I saw it form in to a funnel. The more I watched, it got my attention and kind of scared me,” said Scott Meining, a man who caught the tornado on camera tearing through his oat fields.

On Tuesday the NWS investigators began mapping it’s path and damage, they even traced it’s path in fields a couple of miles outside of Platteville.

NWS investigators say this landspout tornado was relatively narrow, spanning just 100 feet wide.

Teams estimate that the tornado was on the ground for about 30 minutes before it dissipated.

The NWS looked for clues, including flung debris, torn up buildings and downed power lines to connect the dots for how powerful this landspout tornado was.
