As the search continues for the climbers who went missing on Oregon's Mount Hood over the weekend, authorities are predicting the arrival of a winter storm Tuesday.
The storm is expected to deposit at least a foot of snow on the slopes where the climbers went missing. Authorities say whiteout conditions will likely prevent mountaineers or aircraft from conducting their search.
The climbers began their trek up the mountain Friday.
