Avalanche Forecast
Regions: Jasper.
Weather Forecast
Cloudy skies, strong NW winds and mild temperatures with freezing levels around 1400m on Thursday. No precipitation during the day but maybe up to 8 cm overnight Thursday.
Snowpack Summary
Snowpack remains thin and facetted at lower elevations, but is supportive above tree line. Last week's storm snow has buried a surface hoar layer (Jan6) down approx 30cm. Windslabs have formed on Southwesterly alpine aspects and previous significant snow transport by intense winds.
Avalanche Summary
Basal facet avalanches (both slab and loose) have been observed below treeline today. Yesterday, numerous size 2 and a few size 3 natural soft and hard slab avalanches were observed in the alpine. Many of these slides are stepping to ground and running to valley bottom.Â
Confidence
Freezing levels are uncertain on Thursday
