Avalanche Forecast
Regions: Chic-Chocs.
One last day to enjoy the new snow and the mild weather in the mountains before the heat and rain arrive...
Beware of small, isolated wind slabs in the alpine, the triggering of which could have serious consequences on the lower slopes, which still have little snow.

Snowpack Summary
At lower elevations, 10 to 15 cm of low density snow covers the December 23 melt freeze crust, which does not quite support the weight of a skier. As you gain altitude, the crust fades in places to give way to a slightly denser snow interface, covered with 15 to 25 cm of low density snow. In the alpine, the strong to extreme winds of the latest weather events have swept the slopes down to the crust and even to the rocks. However, larger pockets of accumulation are found in downwind gullies and depressions in the alpine and at treeline.
The average height of the snowpack is still very thin, about 35 cm in the valley to 80 cm mid-mountain, and extremely variable from place to place.

Terrain and Travel Advice
- Make observations and assess conditions continually as you travel.
- Watch for areas of hard wind slab on alpine features.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Avalanche Problems
Wind Slabs
Wind slabs may have formed on isolated features, mostly in the alpine.
Aspects: North, North East, East, South East, North West.
