As someone who lives in the valley, this is just a big hype train for the news and media. Yes, it's dumping now, at about 3" an hour. But it's definitely not a "blizzard". There's almost no wind (at least in Cottonwood Heights). And there's decent visibility.
Of course, the retards out on the interstate don't realize that you need to slow down. Listening to my scanner, like TWA said, it's a complete shit-show.
