    Fresh snow may take some time to bond to underlying surfaces. The likelihood of both slab and loose avalanches may increase as snow accumulates throughout the day.

Avalanche Summary

No recent avalanche activity has been reported.

If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Fresh snow is burying previously wind-affected surfaces at treeline and above. In sheltered areas, especially around treeline elevations a layer of surface hoar crystals may exist below the new snow.

A crust buried by roughly 30 cm of snow may be breaking down (facetting), and forming another potential weak layer in the upper snowpack.

The mid and lower snowpack is generally settled and well-bonded.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Watch for fresh storm slabs building throughout the day.
  • Dial back your terrain choices if you are seeing more than 20 cm of new snow.
