A layer of warm air in the alpine may cause wet loose avalanches.
There is a thick crust on the surface that can make travel difficult.

Avalanche Summary
On Wednesday, there were some small wet loose avalanches triggered by skiers in the south.
Snowpack Summary
A thick crust is effectively capping the mid and lower snowpack at the moment. This crust is on aspects and elevations. It may not be present in the very high alpine.
Below the crust we have several layers:
A spotty layer of surface hoar buried 40 cm deep that is unreactive.
A crust in the midpack, at treeline and below.
A crust with facets near the base of the snowpack.
Average depth at treeline is 120-200 cm.

Terrain and Travel Advice
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
- This is a good time for exploring terrain.
