Attention: Interstate 40 Travelers - UPDATED 10:35pm

Interstate 70 is closed westbound at Williams.

-- original posting -- 
The California storm is moving east and the snow has begun in Flagstaff, AZ. This screen capture was done at 7:48pm MST. The forecast is for 16 to 25 inches of snow with the recent model data indicating the upper half of that range may be more likely. Even though Arizona's DoT does a pretty good job with snow removal, that is a lot for any organization. So, please have a contingency plan if the highway is closed.
