Be wary of the lurking persistent and deep persistent problems and continue to practice safe travel habits. Be vigilant for shallow spots that could be likely triggering locations.
Summary
Confidence
Avalanche Summary
One size 2.5 was noted Saturday in the Churchill range area. Its' age is uncertain.
Snowpack Summary
A suncrust has been forming on the snow surface on solar aspects from recent clear days. 15-25cm of snow overlies the Feb 3rd crust, which ranges from 1-3cm thick in the alpine. On shaded aspects it exists up to 2500m and is breaking down due to the cold temperatures. On solar aspects it is up to 2800m. At lower elevations it is 15-20cm thick. The Persistent and Deep Persistent weak layers continue to produce whoomphing and sudden fractures in tests.
Weather Summary

The next three days will be generally cloudy, sunny periods, flurries, light winds, and -4 to -10 °C.
Terrain and Travel Advice
- Avoid shallow snowpack areas, rock outcroppings and steep convex terrain where triggering is most likely.
- Minimize exposure to overhead avalanche terrain, large avalanches may reach the end of runout zones.
Problems
Persistent Slabs
This weak layer, buried 20-40cm deep and human triggering remains possible, particularly in shallow rocky start zones.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
The base of the snowpack is inherently weak and untrustworthy. Human and natural triggering of these basal facets remains possible.
Aspects: All aspects.
Elevations: Alpine, Treeline.
