Unusual natural phenomenon
On June 18, 2008 Mike Hollingshead from “Extreme Instability” documented the advent of the weirdest storm: giant waves of rolling thick fog, cresting over the landscape….Similar weather phenomenon, according to witnesses, happened in England (Penzance, Cornwall) – perfectly defined, very slow moving wall of the densest fog ever seen. Here is another bank of thick rolling fog – this time at Rock Mills Rd. in Rappahannock County, Virginia: Don’t miss other recent storm hunting by Mike Hollingshead. Here are some examples of extremely low-hanging shelf clouds, created by a monster supercell off Yankton, South Dakota. (it spawned a tornado, too) See more on this page.
