Description:
Significant snowfall particularly at higher elevations (above 1600m) is a possibility early in the coming week. This new snow will be accompanied by rising NW winds. As a result, areas of wind slab may be encountered on a range of aspects but especially lee to the NW. Avoid ridge line entry slopes and any steep ground where the wind has deposited snow in the form of stiff slab. The bond between the new snow and the old surface will be suspect as much of the snow will be landing on slippery crusts. Keep in mind that thin cover means that many terrain traps are deep and nasty. If you cannot see due to cloud remain on low angled terrain. While the advisory is currently on Moderate, be prepared for the avalanche danger to increase rapidly from Monday onwards.

Recent Avalanche Activity

Recent Avalanche Activity
A small pocket (Size 1) of windslab (NE aspect, at about 2000m) was triggered by a backcountry user in the Black Peak area on Friday.They were taken for a long ride but fortunately, were not buried or injured. Also, evidence of a wind slab release (Size 1.5) near Wedding Cake Rock Treble Cone backcountry NE aspect, approx 1900m.

Current Snowpack Conditions

Current Snowpack Conditions
Additional snow loading over the next few days will, stress a pack which currently contains sliding layers in the form of crusts and buried facet layers (weak, sugary snow).If an avalanche does trigger on one of these crusts expect a long,fast ride with possibly ugly results.

Sliding Danger

Slide For Life
Hard crusts are present in many areas so keep in mind that you could take a long, uncontrolled slide if you fall or get pushed off balance by even a small avalanche.Crampons and an axe or ski crampons are a wise addition to your touring kit at the moment.
