There are two facts: the drought continues, and the snowpack base is weak and faceted. Where avalanches can be triggered is less certain, and stepping out into bigger alpine terrain still inspires little confidence.
The bottom of the snowpack is weak, comprising facets and depth hoar. Recent warm temperatures and winds have promoted slab development in the mid and upper snowpack. There are fewer reports of this being triggered recently, but be cautious in thin alpine areas with enough slab to propagate.
No new avalanches were observed or reported on Wednesday.
Trace amounts of snow bury surface hoar below treeline and sun crusts on steep solar slopes treeline and above. Wind effect and old, hard-slab are found TL and above. A temperature crust from just before Christmas is now buried 10-20 cm below 1900m.
The mid-pack contains a rain crust which can be found as high as 2300m in southern areas.
The basal third of the snowpack consists of a mix of weak facets and depth hoar.
Treeline snow depths range from 60-100 cm.
Thursday: Trace amounts of snow, cloudy, and moderate to strong west winds. Mild temperatures (-8C to -5C).
Friday: Decreasing West winds in the AM, then increasing in the afternoon with trace amounts of snow.
