Please stick to low angle, low consequence terrain while we all work through this Covid issue. Enjoying the outdoors is important, but keeping the big picture in mind is a social responsibility right now. Having said that, if you do get out for the day, enjoy it!!
Summary
Confidence
High -
Weather Forecast
Tomorrow will be very similar to today for weather. The overnight low will be -7, daytime high of -2 and a freezing level of 1300m. We are expecting some building could during the day, but some solar radiation will also make its way through. As the day goes on, a few flurries are expected, but no significant accumulation. Winds will be about 50km/SW at ridge top.
Avalanche Summary
Nothing new today.
Snowpack Summary
 We have received about 30cm of recent snow in the last few days that continues to be slabbing up with the ongoing wind. The alpine and parts of tree line have new slabs that are still skier triggerable up to 50cm deep. These slabs have improved with the warm temps & falling wind speeds. They may still be reactive depending on what type of surface they are resting on. Expect a slower bond on solar aspects.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Avoid convexities, steep unsupported terrain and rocky outcroppings.
- Be aware of the potential for large avalanches due to the presence of a deep persistent slab.
- Caution around slopes that are exposed to cornices overhead.
Problems
Wind Slabs
New winds and windslabs are building
Aspects: All aspects.
Elevations: Alpine, Treeline.

Deep Persistent Slabs
The deep persistent layer is still a concern, especially in shallow snowpack areas. A large cornice trigger could also be enough to weak up this layer.
Aspects: All aspects.
