Snowpack Summary
Forecast 25-30 cm of new snow Monday night could bring storm totals to 45-55 cm by Tuesday morning. The new snow and strong southwest winds are expected to form large storm slabs that will be very reactive to human triggers at all elevations. Expect the storm slabs to be most reactive on lee features at treeline and above.
The recent snow is sitting on a variety of hard snow surfaces, including crusts and wind scoured snow. Below this, there are several crusts in the upper snowpack, but they are unlikely to be a concern in most areas until the next significant warming event.
Terrain and Travel
- The new snow may require another day to settle and stabilize.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Avoid traveling in runout zones. Avalanches have the potential to run to the valley floor.
