Summary
Confidence
Moderate
Weather Forecast
On Monday expect a mix of sun and cloud and light southeast winds. On Tuesday and Wednesday, light flurries and moderate to strong southeast winds are possible. That said, there's significant model disagreement on amounts. Freezing levels should stay at valley bottom for the forecast period.
Avalanche Summary
No new avalanches have been reported.
Snowpack Summary
Snowpack surfaces are highly variable. Temperature inversions and solar radiation have recently come into play and a melt-freeze crust can be found on steep, solar aspects at treeline and above. On shaded slopes, 25-40 cm of storm snow from Boxing Day continues to facet, and new surface hoar has been reported at all elevations. In areas where recent winds have been light, shaded slopes will likely provide unconsolidated powder. In areas where winds have been stronger, reactive wind slabs may exist, especially in areas where the the slab overlies surface hoar buried by the boxing day storm.Professionals in the region are still keeping an eye on a few other surface hoar layers that developed throughout December which are now buried in the top 100cm. Although these layers may be gaining strength, they are worth keeping an eye on, especially on steep unsupported slopes at treeline and below. In colder and shallower snowpack areas watch for weak basal facets.
