From all the info I've gathered, they still had skins on, weren't riding this particular aspect, just crossing one at a time, and it set off way above them, funneling down where they were. Extremely crappy luck all the way around, sounds like. The UDOT forecaster was still in skins, too.
That's what it sound like to me.
In the world of immediate social media, there seems to be a lot of incorrect info at our fingertips.
