Kernpunkte

Avoid shallow areas on lee aspects in the  alpine, where a small windslab avalanche could step down to the basal facets

    Cornice failures or skier travel in shallow snowpack areas are likely ways to trigger this deep weakness in the snowpack.

Weather Forecast

Sunny skies and light winds from the West will continue on Monday. Light snow flurries are expected on Tuesday but will not amount to much snow. We are moving towards spring like conditions with colder overnight temperatures and mid day temperatures rising above 0. 

Snowpack Summary

Colder daytime temperatures have locked in the snowpack today. The Feb 13th rain crust lies underneath a melt-freeze crust up to 2000m elevation. The melt-freeze crust goes up to 2200m. A mixture of rounded and facetted layers are sandwiched between these upper layers and the weak depth hoar/ facets prevalent in the lower snowpack down to ground.

Avalanche Summary

No new avalanches were observed or reported today.

Confidence

Timing of incoming weather systems is uncertain on Tuesday
