Light precip and SW winds over the next two days as we limp into the New Year.
Look for a bit of a stormy refresh coming through the weekend.
Tonight, expecting some isolated flurries, with little accumulation. Alpine temperature: Low -11 C, with light SW winds.
Thursday: Cloudy with sunny periods and isolated flurries and trace accumulations. High of -8 C. Light SW winds at ridgetop.
Varied surface conditions with aspect and geographic location. 15-25cm of un-compacted snow over a firm mid-pack with facets and depth hoar lingering near the ground. Mid-December persistent layers, including SH, and SH/FC combos can be found down 25-40cm but, only in isolated and sheltered locations, and almost exclusively in the Icefields region.
No new avalanches observed or reported today. Make your field trip observations count! Share them with the local outdoor adventure community on the Mountain Information Network from Avalanche Canada.
In the alpine hard slabs sit overtop of facets. Dec 14th surface hoar to 6mm can be found in sheltered locations up to 2200m.
- Be aware of the potential for avalanches due to buried surface hoar in isolated areas.
- Whumphing, shooting cracks and recent avalanches are all strong indicators of an unstable snowpack.
Deep Persistent Slabs
Be cautious of thick to thin snowpack areas being likely trigger locations. The persistent slabs have the potential to step down to the weakness at the base of the snowpack.
- If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
- Use caution in thin snowpack areas.
