    Despite the low danger ratings, the base of the snowpack remains weak due to basal depth hoar/facets. Consider this layer carefully when looking to travel in aggressive terrain, especially in thin, rocky areas.

Weather Forecast

Light amounts of snow will accumulate in the forecast region over the next few days (~15-20cm). The associated wind will be blowing lightly out of the west. These small inputs will keep the danger rating at moderate in the alpine.

Snowpack Summary

5-15cm low density snow now sit on the Jan 30 crust at 2300m and higher. Isolated soft slabs 15-30cm thick and of little consequence can still be found in the alpine.  Basal depth hoar is still a layer of concern in the region, and is giving moderate to hard compression results.

Avalanche Summary

No new avalanches observed or reported today.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday
