Yet another day without a good overnight refreeze. Temperatures will drop in the morning, but sun exposure can deteriorate conditions rapidly. The rating is for the hottest time of the day.

Check out the Forecaster's Blog on warming and how to stay safe.

The snow surface consists of a melt-freeze crust on solar aspects and shaded aspects up to treeline which transitions into moist/wet snow during the day. Dry snow might still be found on northerly aspects in the alpine above 2000 m. 20-40 cm of recent snow has formed isolated pockets of wind slab on leeward slopes and behind terrain features. The recent snow sits on a series of melt-freeze crusts on all aspects below 1900 m and southerly aspects to mountain top. On North aspects in the alpine, the recent snow sits on dry wintery snow surfaces and possibly surface hoar on wind-sheltered slopes. 

Cornices are large, fragile and failing with warm temperatures. Several natural cornice falls were observed recently. 

Recent periods of warm weather are expected to have helped old persistent weak layers heal, including a few crusts buried over the last month as well as a facet layer 150 cm deep from the mid-February cold snap. 

On Friday numerous wet loose avalanches on all aspects and wet slabs to size 3 on solar aspects were reported. Numerous wet loose avalanches to size 2 and several wet slab avalanches of size 2.5-3 and one size 3.5 were observed on steep solar aspects on Thursday. 

A couple of recent natural cornice failures size 2.5 did not trigger slabs on slopes below except for one which triggered small slab avalanches.

Neighbouring Glacier National Park reported a few very large (size 3-4) glide slab releases last week. Glide slabs are hard to predict and can release at any time, so it is important to avoid slopes with glide cracks.
