With the warm temperatures and freezing level we expect this deep layer to wake up and cause large destructive avalanches.
We are into a period of All Melt, No Freeze.
Large avalanches may run into below treeline. Time to avoid all avalanche terrain.
With the warm temperatures and freezing level we expect this deep layer to wake up and cause large destructive avalanches.
The snow surface likely consists of a mix of hard melt-freeze crust and dry snow depending on aspect and elevation. Sun-exposed slopes may undergo daily melting and freezing whereas northerly alpine slopes could remain dry with potential slabs.
The Feb 3rd crust is the dominant mid-pack layer and make reawaken under periods of intense, prolonged warming or rain.
