The Wyoming Department of Transportation triggered an avalanche early this morning in the Twin Slides avalanche path that crossed the highway. Large and destructive avalanches are certain in some areas. Avoid all avalanche terrain.

TODAY'S AVALANCHE PROBLEMS

PROBLEM TYPE
ASPECT/ELEVATION
CHARACTERISTICS

Wind Slab

Avalanche problem rose
LIKELIHOOD:
SIZE: Large to Very Large
TREND:Increasing
PROBLEM DESCRIPTION
Strong southwest to west winds have formed dense surface slabs on leeward aspects. These slabs lie upon buried snow surfaces that were faceted during several days of bitterly cold temperatures. These slabs are likely to release naturally and could run long distances with depths to five feet.
PROBLEM TYPE
ASPECT/ELEVATION
CHARACTERISTICS

Persistent Deep Slab

Avalanche problem rose
LIKELIHOOD: Possible
SIZE: Very Large- Historic
TREND:Increasing
PROBLEM DESCRIPTION
Very large and destructive deep slab avalanches that could involve the full depth of the snowpack could release naturally today. These slides could run into flat terrain at the lower elevations and impact mature forest.
