Lo esencial

Conditions are primed for people triggering avalanches. Don't let the lure of deep powder draw you into terrain that's inappropriate for the conditions.

    Probabilidad
    Very Likely
    Tamaño
    1–3
    Weaknesses within and under the new snow. Expected avalanche likelihood and size to increase with increased snow and wind-loading. Slabs will be particulary deep and touchy on wind-loaded northerly aspects near ridge crests.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

FRIDAY: Mainly cloudy with scattered flurries, freezing levels around 1200m with moderate winds gusting strong from the southwest.SATURDAY: Mainly cloudy with the possibility of isolated flurries, light south wind and freezing level remaining around 1200m, but cooler overnight temperatures.SUNDAY: Mainly cloudy with flurries bringing 3-8 cm, freezing levels around 1200m with moderate to strong southeasterly winds.

Avalanche Summary

Reports from Wednesday include continued widespread natural slab avalanches up to Size 3 with crown up to 80 cm thick. A remotely triggered 70-185 cm thick Size 2 wind slab was also reported. It was triggered by a skier 5 m away on the ridge.

Snowpack Summary

SOUTHERN AREAS (e.g. Coquihalla): 10-20cm of fresh snow is likely bonding well to the previous rain-soaked snow surface up to treeline elevations. At alpine elevations, touchy fresh wind slabs are likely forming. NORTHERN AREAS (e.g. Duffey Lake): Another 35 cm of fresh snow by Thursday morning brings the storm snow totals to over a metre, which was all redistributed by moderate to strong southerly winds. This has resulted in touchy storm and wind slabs bonding poorly to the previous snow surface that includes facets and large surface hoar on sheltered slopes and/or a sun crust on steep sun-exposed aspects, as well as wind-affected surfaces (e.g. hard wind slab, sastrugi, scoured crust, etc.) in exposed areas. Weaknesses within the recent storm snow are likely also highly sensitive to triggering.
