Natural avalanche activity will taper off as temps cool and winds abate, but human triggering of the persistent weak layer remains likely.
Stick to conservative terrain, and be aware of who is above and below you. With great skiing to be had for the first time in forever, it may feel challenging to remain disciplined on your descent.
This crust-facet combo, created by extended periods without snow earlier this month, remains primed for human triggering. Stick to low angle or densely treed slopes.
40-60cm of snow Wednesday, accompanied by strong winds, has created fresh slabs. These will be deeper and more reactive in wind loaded terrain features.
Avalanche control on Wednesday night produced widespread results, mostly in the size 2-3 range, with some up to size 3.5.
There were several large natural avalanches observed in the highway corridor on Wednesday, with a couple dust clouds reaching the highway.
On Tuesday a group triggered a size 3 avalanche from ridge top in the Camp West area, failing on the Feb 3rd crust. Numerous other human triggered avalanches have been reported in the region on this layer.
Storm snow totals in the past week have reached up to 120 cm. Moderate to strong southerly winds have loaded lee features.
Below the storm snow, a layer of facetted crystals sits on the Feb 3rd crust, and will be the main failure plane of concern in the coming days. This layer is now buried deeply, and it's reactivity will vary from one slope to the next. No obvious signs of instability on the approach does not mean it is a good idea to step out to ski in avalanche terrain.
Unsettled weather persists in to the weekend, with dropping temps, light winds and and convective flurries forecast.

Friday: Isolated flurries (3-5cm). Light/mod S winds Alpine High -11°C.
Saturday: Flurries 5-10cm, light SE winds, Low -11 °C, High -9°C.
Sun: Sunny periods. Light SW wind. Low -19 °C, High -12 °C.
