{"blocks":[{"key":"7pndv","text":"Total snowfall amounts for Wednesday are still uncertain, however; we do know that the new snow will bury recently formed surface hoar (feathery, frost-like crystals). The strong southwest winds may have destroyed some of the surface hoar especially on wind-exposed slopes, but in wind-sheltered areas, the surface hoar may be alive and well unless the rain got to it at lower elevations. If the new snow accumulations add up, a reactive storm slab may exist, especially where it sits above surface hoar or a melt-freeze crust on solar aspects that formed during last week’s sunshine. Fresh wind slabs may be reactive on leeward slopes where the new snow deposits into deeper drifts.

A widespread rain crust from early November that can be found up to 2500 m and buried down around 100 cm and a shallower one from late November down around 30 cm. These crusts have shown no recent reactivity in snowpack testing, however; given the stagnant weather pattern and a decreasing trend in instability, this problematic snowpack structure is not currently listed as a problem. This may change with increased load from new snow and wind and something to keep on your radar moving forward. We may see it transition to our problems page once we see it reach a certain threshold or receive information/ feedback that it’s waking up. \n The snowpack is thin and variable in wind-scoured areas, and it tapers rapidly at lower elevations. Snowpack depths at sheltered upper treeline elevations are nearing 100 cm and beginning to exceed the threshold for avalanches.
