    Size
    1–3
    New snow is building up over a potentially weak old snow surface. Strong winds and rising temperatures could complicate the picture, leading to slab conditions on a variety of slopes. Be alert to changes in snow depth and consistency.

Confidence

Poor - Due to the number of field observations

Weather Forecast

Tuesday/Wednesday: Another vigorous frontal system is expected to bring moderate to heavy precipitation with freezing levels starting around 1500 m but quickly rising to 2000 m, and strong westerly winds. The Coquihalla Pass area is expected to get 5-10cm of snow followed by 25-30mm of rain. Further north should be drier. Continued wet and warm weather is expected for Thursday.

Snowpack Summary

As we begin our forecasting season, we are working with limited information from the field. Early reports suggest there's enough snow for avalanches at alpine and some treeline elevations. Recent snow is likely to have been redistributed into slabs on lee slopes at alpine elevations. This snow may overlie a weak old snow surface (surface hoar, facets and/or a crust) which developed during November's dry spell. Check the bond of the snowpack at this level and take a cautious approach as new snow builds deeper above this layer.
