Avalanche Summary

Snowpack Summary

Surface sun crusts exist on solar aspects to near ridgetops and up to 2000 m on shady aspects. The mid and lower snowpack is stronger and more settled in this region due to the deeper snowpack, but continue to pay attention to shallower areas that will display a weaker snowpack.

Weather Summary

A North Easterly flow will affect the forecast region this weekend. Increased cloud cover and light precipitation will begin Friday night with snowfall accumulation values of 5-10cm (more to the East). Daytime High freezing levels will climb to 1700m. Ridgetop winds will remain in the light to Moderate range.

Terrain and Travel Advice

  • Uncertainty is best managed through conservative terrain choices at this time.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
