In sintesi

We have returned to winter with cooler temperatures and snow accumulation at valley bottom.

Expect the upslope weather pattern to deposit more snow on the Easterly regions.

    Recent snow and recent winds may have formed wind slabs at upper elevations.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Snowpack Summary

Up to 30cm of recent storm snow over the last 48hours overlies crusts up ~2300m and dry snow at upper elevations. Aging wind slabs and fragile cornices may be found at ridge top.

Weather Summary

Wednesday night: Cloudy with scattered flurries. Accumulation: 5 cm. Alpine temperature: Low -15 °C. Ridge wind northeast: 20 km/h gusting to 45 km/h.

Thursday: Cloudy with sunny periods. Accumulation: 5-15 cm. Greater amounts to the East. Alpine temperature: High -6 °C. Ridge wind northwest: 15-35 km/h.

Terrain and Travel Advice

  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
