Natural avalanches are unlikely but human triggered avalanches are still possible. Alpine wind loaded features should be approached with caution.As temperatures rise above zero in the lower elevations, ice climbers should watch for overhead hazards in form of loose wet/dry sluffs or a rock fall.
Strong to extreme southwesterly winds created a few wind slab layers over the last week. Wind slab natural activity seems to have petered off in the last 48 hours.
No natural activity observed. Keep this on your radar as triggering remains possible with the shallow nature of the overall snowpack. This problem is of most concern in wind loaded alpine features, specifically below ridge tops.
Few small wind slabs observed in the last few days across the region. These slabs were found near ridge tops on northerly aspects and did not step down to deeper instabilities.
The snowpack is 50-80cm deep and is weak and facetted. A surface hoar layer is down 15-20cm below 2300m. Strong winds have stripped exposed alpine and tree-line terrain and created wind-slabs in cross-loaded and lee features. Windward slopes are either stripped of snow or the snow left has been pressed into sastrugi.
