Weather Forecast
Very little change is expected over the next few days. However, a small system may be gracious enough to deposit a few centimeters of snow late on Wednesday. This will not be enough of an input to change the danger rating.
Snowpack Summary
The strong winds from the last few days have created wind slabs in lee areas in the alpine. In some areas these wind slabs will be very hard. Otherwise the storm snow from last week has settled to approximately 25cm and sits on top of the Jan 6 interface, a combination of surface hoar and facets.
Avalanche Summary
No avalanches were observed or reported today. However, yesterday, a recreational party triggered a size 2, hard wind slab avalanche on Narao Shoulder, in Yoho National Park around tree line.
