Continue to practice good travel habits: regroup in safe locations, limit the number of people exposed to avalanche terrain, and be suspicious of shallow or rocky ridges and start zones.

    Where dry snow has prevailed through warm temperatures, wind slabs may lurk in exposed alpine terrain. Cautiously approach slopes adjacent to ridges or rocky, shallow terrain.

Avalanche Summary

Small wet loose avalanches were reported Friday with warming temperatures.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

High freezing levels produced moist surface snow up to 2000 m on Friday. As temperatures cool a crust will form. Strong winds have further stripped alpine and treeline terrain. The mid-pack continues to settle and consolidate. Basal facets are found in the bottom 20-40 cm.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.
