Lo esencial

Choose conservative, low-consequence terrain with no overhead hazard.

Reactive storm slabs in combination with buried weak layers are creating dangerous avalanche conditions.

Problemas de aludes

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–3

    Weak layers of surface hoar and facets/crust could exist in the top meter. Recent snowfall has added significant load to these layers, and could make persistent slabs more likely to trigger.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely - Very Likely
    Tamaño
    1–2.5

    Up to 60 cm of new snow arrived in the past 24 hours. Reactive storm slabs can be expected, especially in wind-loaded areas.

Confidence

Moderate

  • Persistent slabs could become more likely with the forecast weather.

Avalanche Summary

On Monday, several large (size 2) natural avalanches were observed in wind-loaded north-facing terrain in the alpine. Read the full report here.

Snowpack Summary

Up to 60 cm of new snow has fallen at upper elevations in the past 24 hours. Strong southerly winds will have redistributed this snow into deeper deposits in wind-loaded areas. This new snow overlies a melt-freeze crust on solar aspects and wind-affected surfaces at higher elevations.

40 to 70 cm of storm snow from the past week may be sitting on a layer of surface hoar, facets or a crust.

Another weak layer consisting of a crust with facets from early February is buried 80 to 100+ cm deep.

The remaining snowpack appears to be well settled and bonded.

Weather Summary

Tuesday Night

Cloudy. 15 to 25 mm of precipitation as snow or rain at treeline. 30 to 60 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1400 m.

Wednesday

Mostly cloudy. 2 to 5 mm of precipitation as snow or rain at treeline. 20 to 40 km/h west ridgetop wind. Treeline temperature -2 °C. Freezing level 1400 m.

Thursday

Mostly cloudy. 1 to 2 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -4 °C.

Friday

Cloudy. 10 to 15 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid freshly wind-loaded terrain features.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Even brief periods of direct sun could produce natural avalanches.
