🌧️🌡️BULLETIN VALID UNTIL FURTHER NOTICE

The warmth and rain expected on Wednesday and Thursday could further affect an already thin snowpack. Currently, most of our forecast area remains below the critical threshold for avalanche activity. Conditions are typical for early season: stay cautious and vigilant! ⚠️

👉 Next bulletin will be issued after the rain … Stay informed and enjoy the mountains safely! 🏔️

In the meantime, take part in our early-season webinar! https://www.facebook.com/share/14wFRr33Lx/

Avalanche Summary

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The heat and rain expected on Wednesday and Thursday are likely to significantly transform conditions in the mountains. Although 20 to 35 cm of snow fell over the weekend of December 7 and 8, the majority of sectors in our forecast area remain below the critical threshold for triggering avalanches. However, the wind at higher altitudes has redistributed the snow, creating heavier accumulations in couloirs and gullies.

The average height of the snowpack varies between 20 and 50 cm at the foot of the mountains. East of Route 299, local accumulations can exceed 70 cm.

The snowpack is typical of early-season conditions. Expect thin snow cover with rocks, trees and stumps buried just below the surface.

Weather Summary

Tuesday evening and night: Intermittent light snow. South wind, 30 to 50 km/h. Warming, maximum -4.

Wednesday: Snow changing to rain. Wind southeast, 50 to 70 km/h. Maximum +1. Freezing level rising to 2600 m.

Thursday: Rain, 20 to 40 mm in total. Wind southwest, 60 to 80 km/h. High +9. Freezing level 2800 m.

Friday: Alternating sun and clouds. Wind west, 30 to 50 km/h. Maximum -7.

We invite you to consult the public weather resources recommended when preparing for a mountain outing and available here, as well as our alpine weather forecast.

Terrain and Travel Advice

Back off slopes as the surface becomes moist or wet with rising temperatures.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
