The new snow remains reactive to human triggering especially in the East where the up slope storm dumped the most snow. Watch the weather inputs Saturday as more than 10 cm of new snow could easily increase the danger again.
Weather Forecast
Low elevation sites on the BC side of the Rockies have not had a good freeze for a few days, and this will continue through Satruday. Up to 10cm more snow at upper elevations from an upslope storm is expected on Saturday.
Snowpack Summary
5-30 cm of new snow from the past two days has fallen with an uneven distribution in the Little Yoho region. In areas with more storm snow the soft slab is poorly bonded to the melt-freeze crusts or old snow layers below. Below this the snowpack is stable and recent tests have not found any weaknesses. Low elevation snow is becoming isothermal.
Avalanche Summary
Storm slab avalanches up to size 2 were noted today in Yoho, Loose moist, size 1 avalanches were also noted.
Confidence
Forecast snowfall amounts are uncertain on Saturday
Problems
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
