Snowpack Summary
New storm and wind slabs will have form throughout the day on Monday. Below this a crust exists on all aspects to around 2500 m and likely to mountain top on sun affected slopes. This crust will likely be found near the surface at low elevations and become moist as the freezing level rises.
The mid and lower snowpack are generally strong and well bonded.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Closely monitor how the new snow is bonding to the crust.
