More than 13 inches of snow, strong winds and frigid temperatures shut down travel in northern Arizona on Thursday as a storm front moved across the Grand Canyon state.
While over a foot of snow was dumped in the mountains and higher elevations, more than inch of inch fell in warmer desert areas around Phoenix.
Authorities temporarily shut down the interstate highways around Flagstaff as crews worked to clear the snow and rescue stranded motorists.
More snow is expected later on Thursday.
And the Arizona Department of Transportation urged drivers to delay their travel until Friday.
