Fresh wind slabs may be building at upper elevations. Watch for signs of instability such as whumpfing, cracking, or hollow sounds.

Thursday night - Cloudy with clear periods / moderate southwest wind / alpine low temperature near -8 / freezing level at or near valley bottom

Friday - Flurries, 5-10 cm, with another 10-20 cm overnight / strong southwest wind / alpine high temperature near -8 / freezing level 1000 m

Saturday - A mix of sun and cloud / light to moderate northwest wind / alpine high temperature near -10 / freezing level 1000 m 

Sunday - Mainly sunny / light northwest wind / alpine high temperature near -3 / freezing level 1700 m

Fresh and reactive wind slabs may form throughout the day with strong southwest wind.

A natural avalanche cycle was observed in the region on Saturday during the last storm. 

5-10 cm of snow is expected to fall on Friday, bringing this week's storm snow totals to about 15-30 cm. Strong southwest wind is forecast on Friday, which will may form fresh and reactive wind slabs in lee terrain.

The recent storm snow sits on a crust in most areas, except on north aspects above about 1500 m where it sits on either wind slabs or soft snow.

Cornices are large and looming along ridgelines. Their release is unpredictable, requiring a large berth if you're travelling above or below them.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
