Weather Forecast

The forecast calls for light snow flurries with 5 - 10cm of accumulation on Tuesday night. The flurries will continue through to the end of the week.  Surface winds will be light to moderate from the Southwest/ West while alpine ridgetop winds will be predominantly moderate to strong from the Northwest.

Snowpack Summary

Light snow flurries producing 3 - 5 cm accumulations throughout Jasper in the past 24 hours.  No significant change to snowpack structure:  windslabs in exposed lee features, faceted midpack at lower elevations, and poor travel with difficult trail-breaking below treeline.
