Snowpack Summary
~5cm of snow covers the previous surface of crust, facets, surface hoar and pockets of thin soft slab. Variable winds have created pockets of soft slab in the immediate lees of ridges on all aspects. Overall the snowpack is now well settled and strong.
Avalanche Summary
Several reports from outside the park boundary of small skier controlled avalanches failing on wind slabs. In Glacier Park, small pockets of wind slab have been reactive to skiers at ridge top and the loose surface snow sluffs on steep slopes. No new natural avalanches have been observed recently.
Confidence
Problems
Wind Slabs
SW winds continue to form wind slabs. Expect wind effected snow on all aspects. Small pockets of wind slab have been reactive to skiers. Extra caution should be used in steep terrain where a small slab could result in a big fall.
Travel conditions are difficult at lower elevations and in the trees.Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.
Aspects: All aspects.
