Head to high north facing slopes to find the best conditions.
Wet loose avalanches remain possible as warm temperatures continue.
Cornices are weak and may break further back on ridgelines than expected. These large loads can trigger buried weak layers on the slope below.
Several persistent weak layers exist in the upper meter of the snowpack. The likelihood of persistent slab avalanches will increase if the melt-freeze crust near the surface breaks down.
Wet loose avalanches are still possible as temperatures remain high and the snowpack has limited chance of refreezing overnight.
On Saturday avalanche activity was limited to size 1 wind slab in wind affected terrain, and loose wet on steep solar aspects.
On Friday, a natural cornice fall triggered a 2.5-sized slab on a northeasterly alpine slope, following natural persistent slab activity from thin rocky northerly terrain near Panorama on Thursday.
The snow surface is either a thin crust or moist snow to 2500 m. High alpine north facing slopes may still hold dry snow above a thick crust from late March.
Several weak layers from early March, mid-February and late January can be found in the mid and lower snowpack. These layers remain a concern where a thick crust isn’t present above.
The base of the snowpack is generally faceted.
