In sintesi

Use caution at higher elevations where recent snow may have formed reactive storm and wind slabs.

The upper snowpack can weaken rapidly during periods of direct sun exposure.

Problemi valanghivi

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2

    Up to 30 cm of recent snow has fallen at higher elevations. Slabs may be most reactive in north-facing terrain shaded from periods of sun. Reactivity is expected to decrease through the weekend, with only light flurries in the forecast.

    Wet loose avalanche activity will remain likely in steep terrain, while exposed to direct sun and/or daytime warming.

Confidence

Low

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanche activity has been reported since Monday, when warm temperatures and sun triggered wet loose avalanches.

Snowpack Summary

Varying amounts of snow continue to fall at higher elevations, particularly on the east side of the region. Recent snow sits atop variable melt-freeze crusts or moist snow.

While weak, faceted layers may exist in the mid and lower snowpack (especially in shallow snowpack areas), these layers are not expected to be reactive while the upper snowpack remains strong and supportive. This could change later in the spring during prolonged periods of above-freezing temperatures.

Check out this MIN report from Thursday from the Crowsnest area for more details.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Investigate the bond of the recent snow before committing to your line.
