Lo esencial

As temperatures begin to drop Tuesday night, storm slabs and cornices are expected to develop in the alpine.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Cornices may begin to form on alpine ridgelines as the wind continues to blow as temperatures cool.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–1.5
    The storm produced an average of 20 cm across the region and an additional 1 to 10 cm of snow accompanied by moderate southwest wind is expected in the alpine Tuesday night. Watch for the formation of fresh slabs, especially in wind exposed terrain.

Confidence

Low - Due to the number of field observations

Weather Forecast

The system that has brought significant rain and wet snow to the forecast region should offer one last pulse Tuesday night. Wednesday marks the start of what looks to be a pretty significant drying trend as cold air begins to descend from the Arctic. No significant precipitation is expected for the forecast period and it looks like there is potential for clear skies by Sunday.TUESDAY NIGHT: Freezing level around 1200 m, moderate to strong southwest wind, 1 to 10 cm of snow possible with rain in the valley bottoms.WEDNESDAY: Broken cloud cover, freezing level holding around 1200 m, moderate southwest wind, trace of precipitation possible.THURSDAY: Scattered cloud cover, freezing level around 1000 m, light variable wind, no significant precipitation expected.FRIDAY: Scattered cloud cover clearing throughout the day, freezing level around 900 m, light variable wind, no significant precipitation expected.

Avalanche Summary

No recent avalanches observed.Please submit any observations you have to the Mountain Information Network here.

Snowpack Summary

Snow depths are around 50 to 90 cm at treeline and alpine elevations, although there may be deeper deposits in wind-loaded areas. Approximately 30 cm of recent snow sits above a layer of surface hoar (north aspects) or a crust (south aspects). All but the highest elevation and/or smoothest slopes are thought to have insufficient snow cover for avalanches to occur at this time.
