World weather photos: 'Ruff' winter about to be tossed aside

An overhead sign warns that Interstate 70 is closed to the east as a tractor trailer heads out of Aurora, Colo., as a late winter storm packing wet, heavy snow and high winds swept over the intermountain West on Saturday, March 9, 2013. Forecasters predict that up to a foot of snow could be left in the storm's wake in some places in Colorado before moving on to the Plains states on Sunday. (AP Photo/David Zalubowski)
