On Sunday, ski cuts produced size 1 storm slabs.

On Saturday, near Fernie, avalanche control with explosives triggered several storm slab avalanches up to size 2.5 on northeast aspects in the alpine, and a few loose dry avalanches up to size 1.5 around treeline. 

On Friday, near Fernie, numerous natural, rider, and explosive triggered storm slab avalanches up to size 2.5 were reported. Also, Numerous loose wet avalanches up to size 1.5 were reported in steep terrain on all aspects below tree line.

On Thursday, there were reports of many small Loose Wet avalanches in steep terrain below tree line across the region.

The top 20-35 cm of low density surface snow has seen little wind effect. Surfaces may be either moist or crusty on steep solar aspects and below 1900 m. 50-100 cm of recent storm snow contains a melt-freeze crust embedded within it as high as 2100 m. This snow buried a variety of old surfaces including sun crusts, freezing rain crusts, or weak snow crystals on shaded aspects.

A spotty layer of surface hoar layer buried in late January can be found 80-120 cm deep. Although we haven't seen any recent avalanche activity, operators continue to track it especially in the Flathead where it is most prominent. In the Lizard range, it's distribution is isolated.

The lower snowpack is generally well consolidated, with a crust/facet layer from early December found near the ground. It is currently considered dormant but could become active later this season.

• Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
• Caution around convexities or sharp changes in terrain.
• Use small low consequence slopes to test the bond of the new snow.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
• Minimize exposure to sun-exposed slopes when the solar radiation is strong.
