Regions: South Coast.

Stormy conditions may lead to rapid changes in the snowpack. We have limited observations from the field. Send us yours at f[email protected].

Confidence

Fair - Due to the number of field observations

Weather Forecast

Wet, warm, and windy for the next couple of days before freezing levels plummet for the weekend. Wednesday: 20-40 mm of precipitation with freezing levels as high as 2400 m in the southern part of the region, cooler and drier in the northern areas, and moderate but gusty southwesterly winds. Thursday: another 30-50 mm of precipitation expected for the Coquihalla Pass area, less in the Duffy Lake area, with freezing levels dropping throughout the day to around 1700 m, and moderate but gusty southerly winds. Friday: Unsettled conditions with isolated flurries and sunny breaks, freezing levels in valley bottoms, and light winds.

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.

Avalanche Problems

Storm Slabs

Continued snow, rain, and wind-loading is expected to maintain a poor bond within and under the recent storm snow.

Be cautious as you transition into wind affected terrain.>Caution around convexities or areas with a thin or variable snowpack.>Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 4
