Avalanche Forecast
Regions: Jasper.
Weather Forecast
An arctic front approaches from the NE and moves south over the forecast region producing snow flurries and cooler temps.Friday: Cloudy with flurries (up to 5 cm). Alpine Low -16 C, High -7 C. Ridge wind light S.Saturday: Cloudy with isolated flurries. Alpine Low -18 °C, High -10 °C. Ridge wind light NE.
Snowpack Summary
Wind slabs and extensive wind effect found in all open areas. Recent warm temps and solar effect have likely created a crust on solar aspects at below treeline. The upper snowpack is a 50 to 80 cm thick slab that sits on three weak layers in the mid-pack. The entire snowpack is faceted after two weeks of cold, dry weather.
Avalanche Summary
Isolated large Na avalanches were observed on a road patrol Wednesday, one windslab from a cross loaded pocket on a W aspect, and one persistent slab on an E aspect. Otherwise there has been minimal activity since the extensive avalanche cycle on February 8-9. Slopes that did not avalanche during this cycle should still be carefully assessed.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
