    Recent snow and wind has created both storm and wind slabs that may remain reactive, especially where sitting atop weak surface hoar crystals.

Confidence

Moderate

Avalanche Summary

Numerous storm slab avalanches, both naturally and explosive triggered, were reported on Saturday, up to size 2.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Approximately 20 to 40 cm of recent snow has buried a variety of crusts, surface hoar, old wind-affected surfaces, or facets.

The mid snowpack is generally well settled with a series of variable crusts and facetted snow.

The snow depth at treeline is 50 to 150 cm.

Terrain and Travel Advice

  • Give the new snow time to settle and stabilize before pushing into bigger terrain.
  • Use small low consequence slopes to test the bond of the new snow.
  • Shooting cracks, whumphs and recent avalanches are strong indicators of an unstable snowpack.
