Winds expected now up to 120 to 130 mph in Sierras with blizzard whiteouts

If you have ever been in a Blizzard whiteout it isn't funny at all unless you happen to be safe and warm in a cabin or house somewhere prepared for a blizzard and warm inside with food etc.

But, now driving towards the Sierras (from either direction)now isn't a great idea simply because you could be stuck without any visibility at all facing closed roads like Interstate 80 and 50 over the sierras.

Presently this is 1-80 over the Sierras from Caltrans:
