    Cornices could start to fail if they see a lot of sun. These kinds of large triggers could cause the deep layers to fail.

Snowpack Summary

We are expecting Tuesday to be the warmest day of the week with freezing levels rising to 3000m.  The avalanche hazard will deteriorate with the daytime heating.  Avoid being near large sun exposed slopes.  Wind slabs are present in the alpine and isolated areas at tree line.  Expect a melt freeze crust first thing in the morning and moist snow by mid day on solar aspects.
