⚠️ Avoid All avalanche terrain ⚠️Soaring freezing levels and solar radiation will result in a widespread natural avalanche cycle on Sunday.
Check out our latest blog.
A crust with weak facets overtop is down 80 to 150 cm. Very large natural and human triggered avalanches occurring on this layer are very likely on Sunday.
If triggered loose wet avalanches may step down to deeper layers, resulting in very large avalanches.
A widespread weak layer exists at the bottom of the snowpack. Large triggers, such as falling cornices or smaller avalanches in motion may have the potential to trigger this deeply buried weak layer.
Numerous naturally triggered wet loose avalanches up to size 2.5 and persistent slab avalanches up to size 3 (very large) were reported on all aspects at treeline and above on Friday.
Very large, natural avalanches are expected to continue to occur on Sunday.
High freezing levels overnight will result in no overnight re-freeze of the snow surface. As a result, the avalanche danger will rise rapidly throughout the day.
A widespread crust is buried roughly 80-120 cm deep. Weak faceted crystals and surface hoar above this crust are contributing to large avalanches across the province and continue to be the primary layer of concern here.
The basal snowpack is generally weak and faceted, with the potential to produce very large avalanches with the forecast of prolonged warming.
