Avalanche Summary
Warm sunny weather over the weekend caused small wet loose avalanches in the southern Rockies (size 1 to 1.5).
Looking forward, new snow may form slabs on wind-loaded slopes.
Snowpack Summary
A cold front crossing the region will bring 5 to 15 cm of new snow by Tuesday afternoon and more into the evening. This snow will bury crusts and wet snow that formed over the weekend.
The upper snowpack consists of various melt-freeze layers. The lower snowpack contains old weak layers that are no longer a concern.
