Generally safe avalanche conditions exist. However, remain cautious in areas without a supportive surface crust or where new snow has accumulated over a crust.

Moderate
Avalanche Summary
A group of riders remotely triggered (from 60 m away) a size 2 storm slab avalanche on a west aspect in the alpine on Saturday. The group was stopped in a safe spot on a flat bench when the avalanche released on a convex roll on the adjacent slope.
Several other naturally triggered storm slabs up to size 2 were reported on sunny aspects in the alpine.

Snowpack Summary
Anticipate crusty snow surfaces in all but north-facing alpine terrain. In some areas, as much as 10 cm may sit atop these old surfaces.
A series of crusts exist in the upper snowpack.

Terrain and Travel Advice
- Carefully monitor the bond between the new snow and old surface.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Be alert to conditions that change with aspect and elevation.
- Minimize exposure to sun-exposed slopes when the solar radiation is strong.
Problems
Wind Slabs
Thin wind slabs may form in areas that receive new snow, these are a particular concern in areas where they overlay a smooth melt-freeze crust.
Aspects: All aspects.
