Avalanche Summary
No new avalanches have been reported. With storm snow and wind forecast, potential increases for slab avalanches to occur on Sunday.
If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.
Snowpack Summary
By Sunday afternoon around 20 cm of storm snow may have fallen, overlying a widespread crust. The bond between old and new snow may be poor, creating reactive conditions. Deeper and more reactive deposits can likely be found near ridglines, on north and east facing slopes.
Below treeline terrain has low snow cover, this storm snow will not change that. Travel conditions are challenging with exposed (or barely hidden) rocks, stumps, and open creeks.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Keep in mind the crust offers an excellent bed surface for avalanches.
- Be especially cautious as you transition into wind affected terrain.
Problems
Storm Slabs
Storm snow (dry or wet) may slide easily on the crust below. Avoid steep or consequential features until the new snow has had time to bond. Greatest reactivity is expected in wind affected features.
