Watch for reactivity within the wind affected pockets of storm snow, especially where it overlies the crust.

Moderate
Avalanche Summary
No new avalanches have been reported. We expect small slabs may have occurred on Sunday with the fresh snow and strong winds - reactivity may linger in wind-affected features. With full sun on Monday, small wet sluffs are possible on steep, south-facing slopes within the new snow.
If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.
Snowpack Summary
Storm snow up to 10 cm can be found, redistributed into wind affected deposits on north and east facing slopes near ridgeline. This recent snow sits over a widespread crust present on all slopes except high elevation, north facing terrain.
Below treeline terrain is snow free or has very low snow cover. Travel conditions are challenging with exposed rocks, stumps, and open creeks.
Check out this MIN report from Slalok for recent conditions and coverage.
Weather Summary
Sunday Night
Partly cloudy with flurries ending early evening. 20-30 km/h westerly winds. Freezing levels around 1000 m.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Keep in mind the crust offers an excellent bed surface for avalanches.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Problems
Wind Slabs
Wind slabs may be poorly bonded to the crust below. Approach ridgelines with caution.
Sun and rising temperatures may increase reactivity.
