Avalanche Summary
Recent reports have been limited.
We expect that with recent snow and rain, human-triggered avalanches will be possible.
If you do go into the backcountry, please consider submitting a MIN report.
Snowpack Summary
Storm totals are expected to reach 30 cm at upper elevations, with moderate to strong southwest winds forming deeper, more reactive slabs on north- and east-facing slopes. At the treeline, especially around Heather Mountain and Peak 5040, precipitation is expected to have fallen as rain, leaving moist surface snow up to 1000 m.
Underneath the new snow, around 5 cm of settling or wet snow sits on a thick, hard, melt-freeze crust that is present up to mountain tops in most areas.
Below treeline, most areas are below the threshold for forming avalanches.
Weather Summary
Sunday Night
Cloudy with 5 to 15 mm falling as snow above 1000 m, greatest amounts in the south. 30 to 40 km/h southwest ridgetop winds. Treeline temperature -1 °C. Freezing level 1200 m dropping to 900 m overnight.
Monday
Sunny. 15 to 30 km/h northeast ridgetop winds. Treeline temperature 3 °C. Freezing level 1700 m.
Tuesday
A few clouds. 10 km/h north ridgetop winds. Treeline temperature 2 °C. Freezing level 1500 m.
Wednesday
A few clouds. 40 to 60 km/h northeast ridgetop winds. Treeline temperature -4 °C. Freezing level drops to 500 m.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
Problems
Wind Slabs
Southwest winds have formed reactive wind slabs on north through east-facing slopes at upper elevations. Watch for steep, convex terrain features, deposits near ridgetops, and cross-loaded slopes.
