Holyoke Tornado

Add to Cart Add to Lightbox Download

I spent Memorial Day chasing storms across the Colorado High Plains. Colorado may not be the first state people think of when it comes to tornadoes. But it actually sees more than 50 a year on average, mostly in the eastern third of the state. Upslope flow causes storms to fire when moist southeasterly winds encounter the Rockies. The Palmer Divide is a ridge east of the Front Range and it creates what's known as the Denver Convergence Vorticity Zone. The changing winds in the DCVZ generates extra spin which makes storms rotate. But many of the tornadoes are weak and short-lived, at least they were on this day. Of the 3 possible twisters I saw, none of them were very clear. This was taken near Holyoke when swirling dust appeared underneath a funnel.
