Avalanche Forecast
Regions: Jasper.
Weather Forecast
The ridge of high pressure that has dominated the pattern for the last week is being pushed out of the area by a southwesterly flow. A cold front will cross the Jasper area on Wed night leaving a maximum of 5 cm of snow. Thursday will see broken skies, no precipitation, moderate NW winds, and alpine temperatures ranging from -5 to -10.
Snowpack Summary
No significant changes to the snowpack in the last 24-hours. Widespread wind effect in most exposed areas at and above treeline has created hard slabs which overlie a weakness of facets or surface hoar down 10-40 cm (depending on location). Tests indicate a shear on this layer, but triggering is unlikely due to the stiffness of the slab.
Avalanche Summary
No new avalanches were observed along the Maligne Lake road today.
