Points saillants

We are returning to the “Green Brick.” Snowpack conditions are relatively stable, with small loose snow avalanches as the primary concern. This could change quickly if we see any significant winds, as there is a lot of loose snow available for transport.

    The recent low density snow has coated steep rock faces and gully walls. The dry loose problem may persist for another day before settling and becoming less sensitive.

Avalanche Summary

No new avalanches observed or reported today.

Weather Summary

The cooling trend will continue through the start of the weekend, with daytime highs around -10°C and overnight lows dropping as low as -25°C. Expect a mix of sun and cloud, with no precipitation over the next few days. Ridge winds will remain light to moderate.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Snowpack Summary

20–30 cm of cold, dry snow sits at the top of the snowpack. Winds have been light, but expect some lee loading in the alpine. In isolated areas, the Jan 24 layer (surface hoar/crust) is down 20–40 cm at treeline and below – watch to see if this layer wakes up with the additional snow load. Below this, the snowpack is generally strong and well settled.
