Regions: Jasper.

20cm of storm snow has improved ski quality over a supportive crust at tree line and above.

Weather Forecast

Expect 5-15cm of new snow Tuesday evening into Wednesday afternoon with light winds from the east, eventually switching to the west. Thursday will be mix of sun and cloud with a high of -3 and  low of -7 degrees. Friday will be variable clouds with slightly cooler temperatures. Light west winds will persist Wednesday to Friday.

Snowpack Summary

20cm of storm snow sits on top of a 10cm thick laminated crust (Nov 11) at tree line, below the crust is 20-30cm of moist snow to ground. Pockets of wind slab exist in the alpine and may rest on a crust where it is expected to exist up to 2600m.  Below tree line is un-skiable due to lack of snow, early season conditions exist at all elevations.

Avalanche Summary

No recent avalanche activity. Field team observed no signs of instability today in the Parker Ridge area.

Confidence

Due to the quality of field observations on Tuesday

Avalanche Problems

Wind Slabs

Isolated pockets of wind slab below ridge line in the Alpine now be buried by 20cm of recent storm snow.
Early season hazards such as rocks, trees and stumps are still visible.Use caution in lee areas. Recent wind loading have created wind slabs.

Aspects: North, North East, East, South East.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
