Avalanche Summary
On Saturday, several small loose dry were reported as snowfall began to accumulate. We expect human triggered slab avalanche activity to have continued on Sunday, within the storm snow.
Snowpack Summary
20-30cm of recent snowfall sits over a melt freeze crust on solar aspects at all elevations, and wind effected surfaces in exposed terrain.
The snowpack below is well consolidated, with a crust/facet layer found near the bottom of the snowpack. It is currently considered dormant, but could become active later this season. Check out the forecaster blog for more information.
Terrain and Travel
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- The new snow could use a day or two to settle and stabilize before we start to tee up the bigger lines.
Problems
Wind Slabs
Watch for pockets around ridgelines, loaded from moderate southwest winds.
Wind slabs may be also build over the day as east/northeast winds pick up so check for wind loading on all aspects.
