There is low confidence in this forecast due to limited observations. As always, and especially when confidence is low, it is essential to supplement this information with your own observations. And don't forget to post them to the MIN!
Weather Forecast
Another 15-25 cm of snow is expected overnight Tuesday throughout Wednesday with moderate to strong southwesterly alpine winds and daytime high freezing levels reaching 1100 m. Thursday should be relatively dry with snow starting in the afternoon and continuing throughout Friday resulting in another 25-40 cm of accumulation with strong southwest alpine winds and freezing levels rising as high as 1500 m.
Avalanche Summary
No recent avalanche observations reported. If you have been out in the mountains, please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
Total snowpack depths are likely around 150 cm at treeline, and 2 m or more at higher elevations. The new snow continues to build weak storm slabs with particularly deep and touchy wind slabs on leeward slopes in exposed areas. However, warm temperatures are promoting rapid settlement and strengthening.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
