    Isolated wind slabs are still present from northerly winds early in the weekend. Riders are less likely to trigger these firm deposits of snow as cold temperatures have soften slabs.

    A weak layer of surface hoar sitting on a sun crust on steep solar aspects is buried down 50-70 cm. It is mostly likely to be triggered at treeline, where the surface hoar is well persevered and a sun crust is present.

Weather Forecast

Continued warming trend, with an incoming storm on Sunday.

Tonight: Clear, -16*C, light W winds

Fri: Cloudy with sunny periods, Alp high -11*C, light SW winds

Sat: Clouds and Sun, Isolated Flurries, Alp high -11*C, light SW winds

Sun: Flurries, Alp high -11*C, Mod SW winds, Fz lvl 1500m

Snowpack Summary

Wind slabs formed early in the week are softening with cold temperatures. These lingering slabs, formed during strong northerly winds, can be found in open exposed terrain. The Feb 15 surface hoar/solar crust is down 50-70 cm. This layer is not been observed to be reactive in stability tests or to skier loads in the past few days.

Avalanche Summary

No new natural avalanches were observed on Wednesday and Thursday.

Early this week public reports of human triggered avalanches failing below surface wind slabs and on the Feb 15 SH/Crust layer. Size 2 partial burial on Avalanche Crest, Vaux Moraine, wind slabs on Cougar Creek East.

Confidence

The weather pattern is stable
