What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

Maximum wind gust estimated was 108 mph.

The wider storm

An upper level high pressure center was located over central Arizona and central New Mexico which resulted in a favorable pattern for efficient diurnal wind fluctuations including upslope oriented winds towards WFO Pueblo's eastern mountains. Weak waves embedded in the upper level northwesterly flow enhanced the lift and the pattern enhanced the deep shear. The result was a very rare mountainous tornado that was observed at around 9,000 feet.

Began near Woodland Park (38.9133, -105.0565).
