    Probabilidad
    Unlikely - Possible
    Tamaño
    2–5
    Persistent weak crystals which formed in November are potentially destructive, and are a bigger issue in the north of the region. Use extra caution in steep, unsupported alpine terrain.

Confidence

Fair - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

Cloudy with light Southerly winds overnight. Some chance of flurries combined with moderate Southerly winds on Thursday, becoming snow overnight and into Friday morning. Expect 5-10 cm of new snow by Friday morning. Unsettled with moderate Southwest winds during the day Friday with freezing levels climbing up to about 1000 metres elevation. Winds becoming strong Southwest overnight and into Saturday morning. Expect 5-10 cm of new snow as the freezing levels climb up to about 2000 metres elevation.

Snowpack Summary

Conditions in the Coquihalla area are quite different to the Duffey/Hurley regions. Reports from the Coquihalla suggest there's less than 1 m of snow in most avalanche areas. On the surface, fairly widespread surface hoar development has been reported. Below this, a small amount of recent storm snow overlies a thick rain crust. In the north, we have very limited observations. That said, I expect a deeper, more complex snowpack where well settled storm snow overlies a mix of crusts and facets which formed in November.
