Points saillants

Hazard levels will spike if we get a larger than expected snow fall. Watch for changing conditions. Loose dry avalanches may be a concern if we get 10cm or more.

Problèmes avalancheux

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Likely
    Taille
    1.5–2.5
    At treeline, these may be buried under the new snow that is arriving tonight. In the alpine, expect another round of fresh windslabs that will build tonight. These slabs may not bond together until later in the week.

    Despite the lack of natural activity, these slabs will likely remain delicate as new snow builds on top. 

Avalanche Summary

Nothing new, however visibility was limited.

Snowpack Summary

We had 5-10cm of snow last night near the divide. The snow came in on the tail end of the wind storm, so many alpine windslabs may be slightly buried on lee aspects. At all other elevations, the fresh wind slabs are still evident and slightly less reactive than yesterday. Unsupported terrain at treeline will be more prone to wind slab failures. As of 3pm this afternoon the latest pulse of snow has laid down about 3-5cm.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

Forecasts conflict at the moment. One is calling for trace amounts of snow overnight, while the other is predicting an upslope storm that could give 10-15cm. Time will tell... Temperatures tonight will fall to -22C and rise slightly to -18C tomorrow. Ridge winds will be around 30km/hr.
