  • Wind slab
Tomorrow, Thursday

Since Tuesday New main problem: wind slab

Danger level is unchanged at 2 (Moderate) above 2800 m and 1 (Low) below. Instabilities now appear as existing rather than forming, and the wet loose avalanche risk is limited to Wednesday's sunny steep slopes, with the previous size 2 risk now only rare. AI summary comparing the two official bulletins.

Summary

Above 2800 m, danger level 2 (Moderate). Lower down, danger level 1 (Low).

Key messages

  • Danger level 2 (Moderate) above 2800 m and level 1 (Low) below; wind slab and recent-snow instabilities are the main concern.
  • Human-triggered instabilities in recent snow are possible above 2800/3000 m, mainly on north-facing slopes near the Ecrins / Les Bans / l'Olan.
  • Wet loose avalanches are possible on steep, sunny slopes at very high altitude during Wednesday.

AI summary of the official Météo-France bulletin. Always read the full bulletin.

Skier-triggered

Some instabilities in recent snow at very high altitude, especially around the Ecrins / Les Bans / l'Olan.

Natural

A few wet loose avalanches in the sun at very high altitude.

Tomorrow

Thursday 12 November

Considerable (3) ↗ Rising

Danger level 3 (Considerable)

Thursday, danger rising. Rain-laden showers may move through during the day, with the rain-snow limit between 2600 and 3000 m. South-southwest wind, sometimes strong.

Snowpack and avalanche problems

New snow

Snowfall (New Snow Problem). Fresh snowfall forming a soft slab on top of existing layers.

Wind slab

Snowdrift / Wind Slab (Wind-drifted Snow). Wind transports snow and builds hard slabs on leeward slopes.

Some instabilities at very high altitude, mainly near the hautes-alpes.

Triggered avalanches

Above roughly 2800/3000 m, and on slopes facing broadly north, some locally easy-to-trigger instabilities may persist this Wednesday. They are located in areas where recent snow fell between Monday evening and Tuesday morning. Rare thin wind slabs may also form near high ridges from the more sensitive west-southwest wind.

Natural avalanches

During Wednesday, a few wet loose avalanches may occur on steep, sunny slopes at very high altitude (above roughly 2800/3000 m), where recent snow may become wet in the sun. Size 1 (small), and very rarely size 2 (medium) near the neighbouring high ridges of the Hautes-Alpes.

Snow quality

Snow cover

Snow cover is still thin in the Oisans, with a light dusting below 2700 m on northern aspects, and the start of a snowpack above 2800/3000 m, especially on shaded slopes. Glaciers are still crevassed in places.

Snow quality

Below 2800/3000 m, snow has been wetted by rain and may temporarily refreeze thanks to the clear spells on Tuesday evening. Above 2800/3000 m, recent snow, sometimes light on sheltered shaded slopes, and more wind-affected near exposed ridges. This Wednesday morning, a few cm of fresh snow may fall locally in showers at these altitudes.

Weather today

A few weak local showers during the day on Wednesday, but without impact on the snow cover. Clear spells possible at times. West-southwest wind.
