Tetons

Moderate avalanche danger exists today. Human triggered wind slab avalanches capable of burying a person are possible. Recent snowfall and extreme winds have built 1 to 3 foot thick wind slabs. These are likely to be hard and stubborn but capable of cracking a great distance and far upslope from the trigger. If you observe drifts or pillows of snow beneath or downwind of terrain features, you’ve found the avalanche problem. You’re most likely to find these wind slabs above 8,000’ in north and east facing terrain. Avalanche danger remains Low below that elevation where less snow exists.

Temperatures will rise into the mid-twenties in the mountains tomorrow with wind speeds in the 20-25 mph range from the northwest. Scattered cloud cover will allow some sunshine through. New snow has continued to be transported by wind today so tomorrow will begin with wind slabs being 24-36 hours old. Any sunshine on the slabs will reduce stability. Expect human triggered avalanches to remain possible tomorrow above 8,000’ with slab thicknesses ranging from 1 to 2 feet thick. Some of these wind slabs may be more than just isolated pockets so employing an observe and evaluate mindset going another day will be helpful, especially if stepping out into bigger terrain, or sunlit and heavily wind loaded slopes.
