    The weak and facetted snowpack is about to be tested by warming temperatures, then some new snow, for the first time in over a month. Triggering of the basal weakness may become possible in areas where the snowpack above still retains some cohesion.

Weather Forecast

The cold ridge of high pressure has finally broke down by a series of lows moving inland bringing warmer moister air and a little precip over the region. Thursday: A mix of sun and cloud.

Snowpack Summary

10cm of new snow through Thursday and moderate winds could create new windslabs in the alpine. New snow will bury a variety of surface; surface hoar, facets and crusts. The upper snowpack remains generally facetted. The mid and lower snowpack is facetted but still generally carries skis.

Avalanche Summary

No new avalanches have been observed or reported.
