Regions

Jasper.

Please no ice climbing between Parker Ridge and Rampart Creek on Tuesday.Uncertainty in final amounts of snow as well as its reactivity on a variety of buried surfaces.Time to step back and assess terrain as you go.Follow AB511 for closures.

Weather Forecast

Tuesday: Flurries. Accumulation: 7 cm. Alpine temperature: High -4 °C. Ridge wind southwest: 20 km/h gusting to 50 km/h. Freezing level: 1700 metres.

Wednesday: Cloudy with sunny periods and isolated flurries. Precipitation: Trace. Alpine temperature: Low -10 °C, High -8 °C. Ridge wind west: 15 km/h gusting to 40 km/h. Freezing level at VB.

Snowpack Summary

Up to 15 mm of new snow since Friday. Sheltered areas tree line and below hold 10-20cm of soft snow over top a strong settled mid pack. Alpine snow has a variety of surfaces . A temperature crust down 10-30cm is decomposing and generally below 2300m on steep solar aspects. A facet and depth hoar layer is at the bottom of the snowpack.

Avalanche Summary

No new avalanche activity observed on Sunday or Monday. On Saturday, one steep loose surface slide was noted in the Mt. Cromwell area at treeline on a due East aspect.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
