Avalanche Forecast
Avalanche Bulletin - Jasper National Park
Snow and wind have developed a reactive layer that when triggered has the ability to step down to deeper instabilities. A cautious approach to avalanche terrain is recommended.
Avalanche Problem 1: Wind Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- Avoid avalanche terrain during periods of heavy loading from new snow and wind.
- Avoid freshly wind loaded features.
Avalanche Problem 2: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
This is a complex problem which is hard to assess and predict. Give yourself a wide margin and make conservative terrain choices. Below treeline this layer is only a concern if you are in a run out zone of a large avalanche path.
Travel and Terrain Advice
- Be wary of slopes that did not previously avalanche.
- Be aware of the potential for wide propagations.
Avalanche Problem 3: Storm Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Storms slabs continue to be an issues as the recent snow settles. Cooler temperatures over the next few days will help heal this problem.
Avalanche Summary
Explosive control work on highway 93 produced results to sz 2.5. We observed avalanches releasing from new windslab as well as one deeper slab avalanche releasing on the Halloween crust. Minimal natural avalanche activity was noticed.
Snowpack Summary
Storm slabs and windslabs have formed over the past 24 hours with wind effected snow specific to exposed lee features - these two problems sit on a recently developed rain crust 30 - 60 deep. A persistent slab between 40cm-150cm thick sits on the Halloween Crust, low in the snowpack. This crust can be found up to 2,700m depending on its location.
Weather Forecast
A cooler and drier air mass is back over the region under a SW flow. Some flurries, moderate gusting strong (ridge top) winds. Overnight snow flurries with freezing levels to the valley bottom. Alpine lows of -13. Winds moderate SW gusting Strong.
