Kernpunkte

It's exploring season! As long as you're ready to travel on a variable crust and limit your travel in isothermal snow, conditions are excellent for all kinds of backcountry travel.

Lawinenprobleme

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–2

    Large, fragile cornices exist. Be aware of overhead hazard, and stay back from overhanging cornices on ridgelines.

  • Loose Wet

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–1.5

    Slushy, isothermal snow conditions can emerge on sun-facing slopes during the heat of the day. Plan your route with this dynamic in mind to avoid getting surprised by difficult travel and rising wet loose avalanche danger.

Confidence

High

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

Avalanche Summary

A cornice failure was observed near the Lions on the North Shore at around noon on Monday, believed to have failed within 12 hours of that time. Check out the report HERE.

Otherwise, no new avalanches have been reported and little activity is expected under current conditions. A wet loose cycle likely occurred over the weekend at all elevations.

Observations are starting to taper off in many regions. If you are heading out into the backcountry, post a MIN!

Snowpack Summary

All of the region's snowpack has seen temperatures well above 0 °C at this point. Clear overnight periods will allow surface crusts to form, particularly above the freezing level, expected to be 1600 m Tuesday night. Limited dry snow may remain on the region's highest north-facing slopes.

Expect surfaces to become moist during the day and even isothermal on sun-facing slopes. Wet loose avalanche danger emerges when this condition is in play, a counterpoint to slip-and-fall hazards when and where the surface is well-frozen. Outside of oscillating surface conditions, there are no layers of concern in the snowpack, which exists mainly above 1000 m.

Weather Summary

Tuesday Night
Clear skies. 10 km/h variable ridgetop wind. Treeline temperature 1 °C. Freezing level 1600 m.

Wednesday
Sunny. 10 km/h west ridgetop wind. Treeline high temperature 4 °C. Freezing level to 1900 m.

Thursday
Sunny. 10 km/h east ridgetop wind, easing. Treeline high temperature 7 °C. Freezing level to 2500 m.

Friday
Sunny before clouding over with light rain starting near end-of-day. 10 to 20 km/h south ridgetop wind, increasing. Treeline high temperature 8 °C. Freezing level to 2600 m.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
