In sintesi

The weather will play a key role in the snow's stability. If it stays warm, low elevation areas will be avalanche prone. If it cools like it supposed to, things will tighten up and get better. This forecast assumes it will cool overnight.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–4
    Watch for these a you approach open areas at treeline. Remember that warm snow will build new slabs quickly.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2–4
    If it cools off as the forecast suggests, these slabs will tighten up. If it stays warm, expect the reactivity of these slabs to go up (easier to trigger).

Confidence

Low - Freezing levels are uncertain on Friday

Weather Forecast

Tonight: Mainly cloudy with isolated flurries or showers at low elevation. Overnight lows are expected to be -9 (likely warmer) and still windy, west winds at 45 km/hr gusting to 85. Tomorrow:  Mainly cloudy. No precip. Strong winds from the west, 25km/hr gusting to 85. The freezing level is expected to rise, but so far there is no indication of that happening outside. Our confidence is low on the freezing level prediction.

Avalanche Summary

There were 3, sz1 loose wet avalanches on the canmore Hill today. Poor visibility kept the observations limited, but there were almost certainly more loose wet avalanches in low elevation terrain.

Snowpack Summary

Warm temps and rain up to 1700m has made for a wet snowpack at lower elevations. Above 1800m the snow is moist up to about 1900m. Above that the temps stayed cool enough to limit the moist snow. Tomorrow, we can expect a melt/freeze crust up to atleast1900m. At treeline the winds continued to blow around what snow it could. Windslab and settlement slabs are likely to be found in lee areas. The alpine remained cool with dry snow and some moderate wind transport.
