Kernpunkte

Although the Avalanche Hazard is Low, Ice Climbers should be cautious on steep solar exposed gulleys.  A temperature inversion and solar input is triggering loose snow avalanches in this terrain.

Lawinenprobleme

    Wind slabs can be expected to be most developed in the alpine and open tree-line ridge tops.

    Solar triggered sluffs entraining loose snow in steep solar facing gulleys.

Weather Forecast

Blocking high pressure and connected ridge is deflecting all weather systems.  A strong temp inversion will peak on Saturday with alpine temps well above freezing expected.  Valley bottom temps will moderate through the weekend.  All temps begin to slide as the new week begins and no precipitation in the near future. 

Snowpack Summary

Variable wind slab in open or exposed terrain.  Sun crust forming  on steep solar aspects due to warm alpine temperatures.  In most areas the snowpack = Surface facets on a supportive mid-pack that is bridging basal facets. 

Avalanche Summary

Numerous loose snow avalanches to size 1 reported along the Icefields Parkway Thursday afternoon on steep solar exposed gulleys (ice climbs).

Confidence

The weather pattern is stable on Friday
