Avalanche Forecast
Regions: Jasper.
The incoming storm will likely make the good skiing we have even better, but watch for changing conditions, especially if the amount of new snow or wind is more than forecasted.
Weather Forecast
Parker Ridge Area
Tuesday: Flurries. Accumulation: 6 cm. Alpine temperature: High -8 °C. Ridge wind southwest: 20-40 km/h.
Wednesday: Mainly cloudy with scattered flurries. Accumulation: 5 cm. Alpine temperature: Low -9 °C, High -7 °C. Ridge wind southwest: 20 km/h gusting to 60 km/h.
Snowpack Summary
Surface Hoar has been steadily growing on the previous storm snow, which is now unconsolidated and faceting with the cold temps. This overlies a variety of old surfaces ranging from hard wind slab, facets and crusts on steep solar aspects. The bottom of the snowpack is continuing to facet.
Avalanche Summary
Confidence
Intensity of incoming weather systems is uncertain on Tuesday
Avalanche Problems
Deep Persistent Slabs
Be cautious of thick to thin snowpack areas being likely trigger locations. Weak facets layers near the ground continue to become weaker with these cold temperatures.
- Use caution in thin snowpack areas.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 1.5 - 3
Wind Slabs
Forecasted light snow and moderate winds may form new slabs on leeward and cross-loaded terrain features. These slabs will probably not bond well to the current snow surface.
- Minimize overhead exposure during periods of heavy loading from new snow, wind.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Aspects: North, North East, East.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2
