Lo esencial

Hazard will increase throughout the day. Avoid avalanche terrain and exposure to runout zones.

Problemas de aludes

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    1.5–2

    New snow and strong winds continue to build storm slabs on all asp and elevations.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–2

    Expect wet loose avalanches to be reactive where precipitation falls as rain.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Don't let storm day fever lure you into consequential terrain.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

On Friday, evidence of a natural wind slab cycle up to size 2.5 was observed in the alpine from the mid-week wind event.

This MIN from Friday describes whumphing and remote-triggering a wind slab from 30 m away on a convex slope at treeline.

Expect avalanche activity to increase throughout the day.

Snowpack Summary

New snow overlies extensively wind-affected surfaces at upper elevations and possibly sun crust on steep solar aspects.

Below 2100 m, a widespread crust is buried 20 to 60 cm deep. The snowpack below the crust is generally well settled and has no significant layers of concern.

Weather Summary

Cloudy. 10 to 15 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Monday

Cloudy. 30 to 35 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Tuesday

Cloudy. 40 to 50 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C.

Wednesday

Cloudy. 35 to 50 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C.
