Keep an eye on snow accumulation and be prepared to dial back your terrain selection throughout the day. New storm slabs will increase in size and sensitivity to triggering.
Summary
Confidence
Low - Uncertainty is due to the track & intensity of the incoming weather system.

Avalanche Summary
On Saturday ski cutting produced a few size one wind slab avalanches on east aspects at treeline.Â
Snowpack Summary
New wind and storm slabs will likely form throughout the day on Monday. A crust exists on all aspects to around 2500 m. This crust will likely become moist at lower elevations as the freezing level rises.
At 40 to 70 cm below the snow surface a sun crust exists on solar aspects, and weak surface hoar crystals sit on shaded aspects from early March. Reports suggest this layer is bonding well. The mid and lower snowpack are generally strong and well settled.
Terrain and Travel
- Watch for fresh storm slabs building throughout the day.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Storm Slabs
New storm and wind slabs will likely form throughout the day. Size and sensitivity to triggering will be greatest near ridge crests and steep roll overs on north and east facing terrain where wind loading is likely to occur.
Aspects: All aspects.
Elevations: All elevations.
