As you transition into wind-affected watch for pockets deeper cohesive wind slab that may remain reactive to human triggering.
Below the freezing line, the potential for wet loose avalanches still exists.

Avalanche Summary
On Friday, a natural wet loose and glide slab avalanche cycle was observed from the rain event. Several avalanches were reported up to size 2 on all aspects at all elevations.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
Last week's storm resulted in slabs at higher elevations where snow remained dry. Storm slabs overlie previously wind-affected surfaces on south and east-facing slopes. At treeline and below the snowpack is saturated and refreezing.
The mid-snowpack is well-settled. The lower snowpack consists of several crusts with weak faceted crystals above and below that are beginning to heal and bond to each other.
Snowpack depths are roughly 145 to 185 cm at treeline and taper rapidly below 1500 m.
Weather Summary
Sunday Night: Temperatures and freezing level starts to fall with freezing level around 1000 m. Dry. Mix of cloud and stars. Light southwest wind.
Monday: Trace to a few cm of new snow. Mix of sun and cloud. Freezing level rising to near 1500 m. Light southwest wind.
TuesdayNil to a few cm of new snow. Freezing level near 1000m. Mix of sun and cloud. Light southwest wind.

Terrain and Travel Advice
- Avoid areas where the snow feels stiff and/or slabby.
- The best and safest riding will be on slopes that have soft snow without any slab properties.
- Avoid terrain traps where the consequence of any avalanche could be serious.
Problems
