In sintesi

A storm is on the horizon! If the storm comes early, the danger may rise earlier than forecast. Watch for local snowfall amounts in your area.

    The basal depth hoar, crust layer is dormant for now. Currently it is only possible to trigger this layer from extreme terrain in thin snowpack areas. This layer will likely become more reactive as we get some new snow loading it.

Weather Forecast

The jet stream is coming back over us and bringing westerly winds, precipitation and warmer temperatures! Precip is forecasted to start on Monday afternoon with up to 10 cm Monday overnight, then a lull on Tuesday before a bigger storm hits on Wed. Alpine temps will be -10/-15 and winds moderate to strong from the SW starting Monday PM.

Snowpack Summary

5-10 cm of facetted snow with variable wind effect sits on the spotty January 30th surface hoar. This will be the layer to watch as we get more snow. In the alpine, this snow sits on either firm windslabs or suncrusts. The basal facet/ depth hoar problem persists but is well bridged in deeper snowpack areas.

Avalanche Summary

No new avalanches have been observed or reported.

Confidence

Intensity of incoming weather systems is uncertain
