Ongoing snow and winds have produced dangerous avalanche conditions. Stick to low-angle terrain with no overhead hazard, like large avalanche paths or cornices.
Ongoing snow and wind will continue to form reactive storm and wind slabs overnight and into Tuesday. New snow may take some time to bond to underlaying snow surfaces.
With ongoing wind and heavy snow overnight, surface slabs are expected to remain reactive through Tuesday.
New storm and wind slab formation will continue through the day on Tuesday. The new snow may take some time to bond to the underlying snow surfaces, especially on south aspects where a thin melt-freeze crust may be present.
The middle of the snowpack is firm and well-consolidated. Weak faceted grains exist near the base of the snowpack but have not yet created a major problem, unlike some of the neighboring regions. However, we continue to track this layer and may see a problem develop as more snow accumulates and slab formation continues above it.
The average snowpack depth is around 150 cm while up to 250 cm can be found in wind-loaded areas.
