Summary
Confidence
Poor - Due to limited field observations for the entire period
Weather Forecast
A Pacific frontal system is moving through the interior regions Friday and extending into Saturday. This will bring strong ridgetop winds, and moderate amounts of snow, especially in upslope areas. After the front passes, a weak ridge of high pressure will push into the region bringing dryer, cooler, and clearing conditions that will last through the weekend. Freezing levels will stay in the valley bottom through the period.
Avalanche Summary
No new avalanches were reported. If you and your friends have been out exploring and riding in the backcountry, and have some observations to share please send an email to forecaster@avalanche.ca.
Snowpack Summary
New storm snow will bury previously formed
wind slabs, and continue to build storm slabs. An early November crust exists near the bottom of the snowpack, however there is no information leading me to think that it could act as a weak layer. Be aware of instability signs such as whumphing, which is a good indicator of a weak layer buried beneath and an unstable snowpack. Snowpack depths on average are near 80 cm @1700 m, and near 100 cm at higher elevations. Below treeline may still be below threshold. Snowpack and conditions vary across the region, its important to be aware of YOUR local conditions.
