Hee hee. Holy shit is what I thought--I was coming back from one of my favorite photo sites and saw this in my rearview mirror. I pulled off the road by the airport and found that I had pulled off at the right place, the unharvested crop and worked over field were at the perfect angle. I got a few shots of the phenomenon but this was the best, at the moment it crossed from the worked over field to the grain. It dissipated quickly then.
Vera, it's an atmospheric phenomenon of heat/rising air similar to a tornado but commonly called a dust devil or whirlwind...saw a dozen of them at once in Mexico just south of El Paso, Texas, they appear and disappear. This was by far the largest I had ever seen, right here in Hemet, California.
the story reminds me of visiting Utah when I was a kid, we were swimming in Salt Lake and there was this water spout and it was huge! and reached up the sky! apparently as harmless as a dust devil because while I was having my kid heart attack no one else seemed to care lol.
Chet, it was broadcast on the ABC News channel (KABC7, Los Angeles) on the 6pm weathercast with Dallas Raines a coupe of weeks ago. Several of my friends saw it and commented.
