Regions

Jasper.

Expect the hazard to increase over the day Monday if forecasted snow amounts and wind materialize. Make terrain choices based on changing conditions.

Weather Forecast

The westerly flow is expected to bring snow and warmer temperatures though the night and leading into the week. Initial snow amounts are expected to be around 10cms for the S end of the forecast area Sunday night and through the day on Monday. A mod south wind could transport this snow and create a reverse loading pattern from the last wind event.

Snowpack Summary

We have a supportive mid-pack above 1,900m. A concerning weakness can be found consisting of decomposing surface hoar and or facetted grains. This may be 30-70cm down and the forecasted new snow could overload this layer and increase the hazard over the day Monday. Moderate winds have stiffened the surface snow in open areas above tree line.

Avalanche Summary

No new avalanches have been reported.

Confidence

Intensity of incoming weather systems is uncertain

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
