Avalanche Forecast

Moderate

Natural avalanche activity has mostly tapered off since last weekend's storm. A few size 1 loose moist avalanches observed yesterday from steep solar aspects.

Artillery control produced excellent results on Tupper and Macdonald the night of the 7th, with most shots producing sz 2 to sz 3 avalanches from steep start zones, running out onto valley bottom fans. Debris moved fast, likely picking up speed and mass on the buried surface hoar.

50-70cm of storm snow sits on a sun crust on steep solar aspects. In sheltered locations, this new snow sits atop surface hoar. Strong SW winds at the end of the storm created surface slab conditions on exposed Treeline and Alpine slopes.

There is a dense, well-settled mid-pack without any significant weak layers.

The Nov 9 crust is down 1-1.5m. The base of the snowpack is comprised of several dense, melt-freeze rain crusts formed in October.

A windy weekend storm will bring light to moderate snow through to Monday.

Tonight: Flurries, trace of snow. Alpine Low -6. Moderate South wind, Freezing level(FLZ): 1000m

Sat: Flurries, 10cm. Alpine high -5 °C. Moderate gusting to Strong SW winds. FLZ: 1400m

Sun: Mix of sun and clouds w/flurries, 6cm. Alpine high -7. Moderate to strong SW winds. FLZ: 1100 m

Mon: Flurries, 7cm. Alpine high -10. Light SW wind. FZL 900m

• Be careful as you transition into wind-affected terrain.
• Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
• Carefully manage your exposure to overhead hazards.
