Recent winds and snow have formed wind slabs
Pockets of previous wind deposited snow overlies the Nov 4 rain crust. Test results are mixed on this layer but appears to be becoming more reactive with increased loads and continued faceting
Deep persistent slabs are best managed by:
Cornices are best managed by:
Tonight: Mainly cloudy with isolated flurries. Precip: Trace. Alp temps: Low -8 C. Ridge wind SW: 10-30 km/h.
Monday: Mainly cloudy with isolated flurries. Precipitation: Trace. Alpine temperature: High -6 C. Ridge wind west: 10-30 km/h.
Tuesday: Flurries. Accumulation: 9 cm. Alp temp: Low -9 C, High -7 C. Ridge wind SW: 20-35 km/h.
The snowpack is highly variable depending on location. Height of snow at Parkers is ~100cm at treeline. The Nov.4 crust up to 2600m, and is up to 70cm deep. Test results on this crust have shown a mix of mod sudden/resistent planar results. Continued wind slab develop on N and E aspects ridgetop down into treeline. Basal layers continue to weaken
Several natural wind slab and dry loose avalanches in the alpine on north aspects have been observed in the Icefields, Jasper and Bald hills region over the past 72 hours. Natural avalanche activity has decreased over the last 24 hours with the winds reducing and clear skies having moved into the area.
