On Wednesday, we received report of a size 1 wind slab out of an unsupported lee feature observed from the highway.

Looking forward, reactive wind slabs may exist in lee terrain features on a variety of aspects due to a recent shift in wind direction.

10-20 cm of new snow likely fell between Thursday night and Saturday morning. This adds to about 20 cm of recent, wind-affected snow. A change in wind direction may mean that wind slabs exist on many aspects.

The White Pass area has a deep snowpack without any layers of concern. The Tutshi Lake / Paddy Peak area should be assessed on a slope by slope basis, as some lingering snowpack weaknesses may still exist on isolated slopes. The Wheaton's shallower snowpack is dominated by hard wind slabs overlying sugary facets and depth hoar. It's an untrustworthy snowpack structure that requires conservative terrain selection and diligent travel habits. 

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Seek out sheltered terrain where new snow hasn't been wind-affected.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
