Points saillants

Quick cool down overnight Friday will tighten up the snowpack for now and into the forecasted future.

(cautiously, he predicts..) It appears to be setting up for a stellar week of touring and exploration in the Rockies!

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2.5

    SW winds created fresh wind slabs. These new wind slabs sit over a variety of firm surfaces including wind effected snow and sun/temperature crusts.

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1–3.5

    Fresh cornices are proving to be reactive with loading.

Weather Forecast

Variable weather through out the forecast region with rain and/or snow possible at TL and below. Best to select area specific forecasts via Avalanche Canada's Mountain Weather Forecasts resources.

Snowpack Summary

Varied snowpack with elevation and aspect. Sunny, BTL slopes mostly below threshold, definitely out below ~1600m. TL and below, expect a mixed bag of dust on crusts with improving support underfoot as the temps cool. Above TL, new precip and strong winds will build new windslabs on N to E aspects. Sheltered areas TL and above, could be epic!?

Avalanche Summary

Crazy winds and mixed precip in the Three Valley Confluence at all elevations. Poor visibility TL and abv. on patrol in Maligne. Avalanche control produced small surface slabs (wind) and loose wet , up to sz 1.5.

Confidence

Forecast snowfall amounts are uncertain on Saturday
