Avalanche Forecast
Regions: Little Yoho.
Travel is very difficult in the Little Yoho forecast region because of an unconsolidated snowpack. If you re fortunate enough to get up high, be vigilant in your route choices, the Nov crust is very susceptible to triggering. AB
Weather Forecast
A slight warming trend has come over the forecast region. Light snowfall on Firday will likely not amount to more than a few cm's. This will not have a drastic affect on the danger rating.
Snowpack Summary
55cm of storm snow overlie a crust (Nov 6), which is only 15cm above the ground. For the most part the snowpack lacks cohesion and forecasters were breaking through on skis to the ground. Consistent whumphing as forecasters skied below Mt. Field today.
Avalanche Summary
No avalanche activity was observed or reported in the Little Yoho region today.
Confidence
Due to the number and quality of field observations on Tuesday
Avalanche Problems
Deep Persistent Slabs
The primary problem in the snowpack is the interface between the recent storm snow and the November 6th and 24th facet/crust interfaces. Watch for remote triggers.
- Use conservative route selection, choose moderate angled and supported terrain with low consequence.
- Watch for whumpfing, hollow sounds, and shooting cracks.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 2 - 3
Wind Slabs
The wind affect will be encountered above treeline and above in wind exposed terrain.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Watch for whumpfing, hollow sounds, and shooting cracks.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 2 - 2
