General Avalanche Advisory
At the upper elevations, approximately two feet of snow has fallen since Saturday afternoon. Strong southwest winds have loaded the snow onto leeward aspects. Skiers or riders can easily trigger wind slabs today in very steep terrain with depths to three feet above 7500 feet and one foot below that elevation. The chance also continues for older buried weakness to fail and large avalanches could be triggered that are likely to have severe consequences. Evaluate the snowpack to avoid areas of wind loading and make conservative decisions regarding areas where the persistent weak layers remain a concern.
TODAY'S AVALANCHE PROBLEMS
TYPE OF PROBLEM
Soft slabs formed by southwest winds could be triggered by humans on steep wind loaded starting zones. These slabs could increase in sensitivity today in areas where they are weakened by periods of direct sunlight and warming temperatures.
TYPE OF PROBLEM
New snow and winds have increased the load on persistent weak layers. At higher elevations, slabs could fail on faceted snow and/or crusts buried by the last storm on February 2nd and have depths of two to four feet. At lower elevations, where the snowpack is shallow and wrought with weak faceted snow, older layers may fail near the ground with depths to two feet.
