Avalanche control planned for EEOR Nov 17th between 12:00 & 16:00. Please no recreating in this area.

Confidence

Moderate - Uncertainty is due to limitations in the field data.

Weather Forecast

Finally! Cooler temps. Winds are expected to continue in the Strong range from the NW

Avalanche Summary

Avalanche debris noticed in the slide paths below EEOR today

Snowpack Summary

Limited data is available so far this season as forecasters haven't been out due to low snow amounts and challenging travel. Currently 50-70cm of snow is at treeline with a temperature crust related to recent rains 10-20cm off the ground. We don't have a firm grasp on how high this crust goes at this time due to limited field observations. Windslabs are being reported in alpine areas along ridgelines and crossloaded features. 

Terrain and Travel

  • Watch for fresh storm slabs building throughout the day.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
  • Be alert to conditions that change with elevation, aspect and exposure to wind.

Avalanche Problems

Wind Slabs

Wind slabs will be developing in open terrain with the new snow and winds.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Very Likely

Expected Size: 1.5 - 2.5
