Points saillants

Winter seems to be holding out. A little snow has fallen aloft and another system should leave its mark towards the end of the week. Remember that conditions are highly variable and windy slabs could form on leeward slopes.

    On Monday night and into Tuesday, moderate northerly winds are forecast, conducive to snow transport. The northerly winds will be short-lived, turning southeasterly from Wednesday onwards. Wind slabs may then form on the north-western slopes on Wednesday.

Avalanche Summary

Snowpack Summary

At higher altitudes, above 600m, we received 5 to 10 cm of new snow between Sunday and Monday. We may receive another 5 cm by Tuesday. In the valleys, the precipitation fell either as rain or slush.

This new snow is covering a refreezing crust that formed last week with the warm temperatures and solar heating.

The average height of the snowpack is around 100 cm, but is highly variable from one area to another. The wind has greatly redistributed the snow in the alpine region, creating great spatial variability. Some slopes are back to rock...

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Wind slabs may be poorly bonded to the underlying crust.
