Lo esencial

Continued stormy weather has resulted in elevated avalanche danger. Alpine and tree line areas above the snow line have developed deep storm slabs.

Problemas de aludes

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–3
    Recent strong winds and steady snowfall have formed storm slabs that increase in depth and reactivity with elevation. Expect deeper slabs and touchier conditions on the lee side of wind exposed terrain features.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–2
    Forecast rain at lower elevations may release as loose wet avalanches in steep terrain that is not well supported.

Confidence

Moderate - Freezing levels are uncertain on Wednesday

Weather Forecast

WEDNESDAY: Snow, accumulation 30-40cm Tuesday night through Wednesday / Moderate south wind / Alpine temperature 0 / Freezing level 1300 m THURSDAY: Cloudy with sunny periods / Light east wind / Alpine temperature 2 / Freezing level 1400mFRIDAY: Cloudy with isolated flurries / Light to moderate south wind / Alpine temperature 3 / Freezing level 1500m

Avalanche Summary

Loose wet avalanches up to size 1.5 were reported from the Hollyburn area on Monday. On Wednesday expect reactive storm and wind slab avalanches in the alpine and tree line elevation bands where the recent precipitation has fallen as snow. Below tree line expect small loose snow avalanches where rain has soaked the snowpack.

Snowpack Summary

Additional new snow is expected at alpine elevations tonight and tomorrow. The freezing level is uncertain on Wednesday. Expect to see a mix of rain and snow at tree line and snow in the alpine. This new snow at upper elevations has been redistributed by moderate to strong southwest wind and is sitting on a well settled lower snowpack. Rain below tree line will continue to soak an already moist and/or wet lower snowpack.
