Friday: Mainly cloudy with light flurries beginning in the evening. Light northeast winds. Freezing level to 1600 metres with alpine high temperatures of -2.Saturday: Cloudy with continuing scattered flurries bringing about 5-8 cm of accumulated new snow by end of day.. Light northeast winds. Freezing level to 1600 metres with alpine high temperatures around -1.Sunday: Cloudy with isolated flurries and a trace of new snow. Light northwest winds. Freezing level to 1500 metres with alpine high temperatures of -3.

Several more loose wet avalanches were reported on Tuesday. Explosives control in the Kootenay Pass area produced eight results from size 2-2.5. Another natural size 2 was noted for releasing two hours after the sun had left the slope.Avalanche activity through the end of the weekend into Monday focused on a natural solar induced loose wet avalanche cycle on south and west aspects in the alpine an treeline to size 2. On Friday reports indicate numerous size 2-2.5 natural and explosive controlled storm snow avalanches running on all aspects in the alpine and at tree line. There were also several skier triggered storm slab avalanche size 1.5-2 both Friday and Saturday on north aspects in the alpine and tree line.

A mix of light rain and wet flurries brought about 7 cm of new snow to the region on Wednesday. Where it arrived as snow, this precipitation buried a moist crust on solar aspects and a new layer of surface hoar on sheltered north aspects.Last week's snow was redistributed by predominantly west and southwest wind, forming wind slabs at high elevations. On north aspects these older slabs may be sitting on a layer of surface hoar about 25-40 cm below the surface.A mix of weak layers exists 50-100 cm below the surface, including small surface hoar on shady aspects and a crust on solar aspects. These layers are expected to have gained strength from recent cycles of warming and cooling. Like other deeper weak layers that formed in January and December, they are considered dormant at this time. These deeper layers include several surface hoar and facet layers 1 to 2 m below the surface and a crust/ facet interface near the base of the snowpack.
