Weather Forecast

Monday is dry and warm, with the freezing level near 3000 m.  On Tuesday, cloud may build up and the freezing level drops to near 1500 m. Light snow or flurries begin on Wednesday afternoon. Winds are light to moderate from the north.

Avalanche Summary

A cornice fall triggered a size 1 slab on Friday. Otherwise, no new avalanches have been reported.

Snowpack Summary

Cornices may be large and fragile. In some locations, wind slabs may be found in alpine terrain. On high, shady slopes, low density dry snow overlies a crust. Sunny slopes are likely to follow a melt-freeze cycle over the next few days (soft and weak surface by day; with limited refreezing by night). Recently formed crusts at or near the snowpack surface are strong and supportive below about 2200 m. At higher elevations and on shady aspects, these crusts have less strength. The mid and lower snowpack are generally strong and well-consolidated. Below treeline, there is limited snow cover.

Avalanche Problems

Cornices

Large and fragile cornices may collapse. Isolated areas of wind slab may also be found.
Avoid steep slopes below cornices.>Be cautious as you transition into wind affected terrain.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 5

Loose Wet

Watch for loose wet avalanches on steep sunny slopes.
Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.>

Aspects: North, North East, East, South East.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 3
