Regions: Jasper.
Weather Forecast
The freezing level will approach 1800 m on Saturday afternoon with clear skies. Winds will be light from the SW. On Sunday, temperatures will moderate, skies will cloud over and light flurries are possible.
Snowpack Summary
The recent storm snow appears to be bonding well to previous surfaces. Soft slabs are developing below alpine lee ridge lines with gusty moderate SW winds . At lower elevations, this snow is sitting on a weak and faceted midpack. Snow that is plastered to steep rocky terrain will most likely sluff once exposed to the sun for prolonged periods.
Avalanche Summary
Temperatures today remained below freezing, however, several size 1-2 wet snow avalanches were observed on steep south facing slopes below treeline due to intense solar radiation. On Saturday, temperatures will approach double digits with high solar radiation, this will result in a High avalanche danger.
Confidence
Timing or intensity of solar radiation is uncertain on Saturday
