Avoid exposing yourself to overhead hazards and be extra cautious near ridges where fresh wind slabs are most likely to form. A thin snowpack barely hides hazards like rocks and logs.

Moderate
Avalanche Summary
There are only a few eyes out in the mountains, but I haven't received recent reports of avalanches. If you do get out riding please consider reporting in the MIN,
Snowpack Summary
Upper Snowpack: Recent new snow will be redistributed by the wind (aka form windslabs). Below this is a layer of wind hardened or settled snow.
Lower Snowpack: cold temperatures have weakened and faceted the snowpack. A basal rain crust sits near the ground.
Total snowpack depths at treeline elevations are 40-70 cm and in the alpine 60-120 cm. Below treeline elevations remain below the threshold for avalanches.
Weather Summary
Sunday Night
Trace to a few cm of snow ending overnight as the area transitions to a colder and dryer pattern.
Monday
Dry with a mix of sun and cloud, Light wind from the northeast and temperatures falling to the -15 to -20 C range.
TuesdayVery similar to Monday, just a bit colder.
WednesdayAn incoming disturbance should flip the wind back to the southwest, carry in clouds, and warm temperatures to around -10 C. Only a trace to 10 cm of snow is expected.
More details can be found in the Mountain Weather Forecast.
Terrain and Travel Advice
- Be especially cautious as you transition into wind affected terrain.
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Avoid terrain traps where the consequence of any avalanche could be serious.
Problems
Wind Slabs
Wind slabs may be found in leeward terrain just below ridgecrests. However, forecast northerly winds may lead to an unusual pattern.
