Does green mean go? No! Keep your wits about you: avalanches are still possible in isolated areas.

Weather Forecast

We are in for a dry week. Temperatures warm on Sunday, when the freezing level is forecast to spike up to 2800 m and stay there through Monday. Winds are light to moderate from the north.

Avalanche Summary

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.
Be cautious as you transition into wind affected terrain.>Avoid steep slopes below cornices.>

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 3 - 5

Loose Wet

As temperatures warm this weekend, watch for loose wet avalanches on steep sunny slopes.
Minimize exposure to sun exposed slopes when the solar radiation is strong.>

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

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 3
