Avalanche Summary

No new avalanches were reported on Thursday.

On Wednesday, there were a few small (size 1) dry loose avalanches and sluffing reported out of steep, sunny slopes.

A few small wind slab avalanches were reported on Monday and Tuesday, and one larger size 2 wind slab was remotely triggered in the Hurley area.

Snowpack Summary

A couple cm of new snow is expected to accumulate throughout Saturday, covering a variety of surfaces. In sheltered terrain, it will land on facets and surface hoar, while on exposed slopes it will overlie wind-affected snow and a sun crust.

30 to 50 cm overlies a weak layer from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be faceted grains or surface hoar. This layer hasn't been producing avalanches, but may become a problem when more snow arrives.

The mid and lower snowpack is strong and bonded.

Terrain and Travel Advice

  • The snowpack is generally stable; it may be appropriate to step out into more complex terrain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
