Wind slabs can still be a concern at higher elevations. If the inversion is strong, avoid snow that is becoming moist as it could produce a small avalanche.

Avalanche Summary

No significant avalanches were reported.

Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network.

Snowpack Summary

Wind affected snow exists in exposed terrain at higher elevations. Surface hoar is widespread on slopes sheltered from the sun and wind at all elevations. A suncrust has formed on steeper slopes exposed to the sun.

A buried layer of surface hoar may be present in isolated areas, located 10 to 30 cm beneath the surface. The mid snowpack is generally well settled, with an early November crust buried 50 to 100 cm deep.

Snow depths at treeline range from 80 to 150 cm and decrease quickly at lower elevations.

Weather Summary

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

Problems
