Avalanche Forecast
Regions: Little Yoho.
Ski conditions are excellent in Little Yoho right now - just watch out for triggering wind slabs. Ice climbers - Mt Dennis should be fine as natural avalanches are unlikely, but the exposed slopes on Mt Stephen are more suspect (Twisted, etc).
Weather Forecast
An arctic ridge of high pressure is descending into the area and will dominate for the next few days. Dress warm, as lows of near -30 are expected with daytime highs reaching -18 under clear skies with light winds from the north. It looks like the temperatures will start to moderate and rise slowly by Wednesday.
Snowpack Summary
The storm snow from last week has settled and now tops a 150 cm snowpack at treeline. No active weak layers exist within the snowpack, and the main issue is wind slabs in alpine areas that were formed by strong winds over the past week. The snowpack will continue to stabilize with the onset of the cold, arctic air over the next few days.
Avalanche Summary
No new avalanches observed or reported on Sunday.

Wind Slabs
Pay close attention to the texture of the snow surface as you are traveling, and watch out for dense, wind drifted snow which could indicate the presence of a wind slab. Areas near ridge crests or sides of gullies are obvious places to find these.
- If triggered the storm/wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: North, North East, East.
