Avalanche Forecast
Avalanche Bulletin - Banff, Yoho, and Kootenay National Parks
The new snow is bonding poorly to the old snow and is presently touchy. Storm slabs will likely give way to wind slabs and should stabilize fairly quickly. Watch out for large open areas, or gullied terrain that can gain mass quickly.

Travel and Terrain Advice
- Avoid ice climbs exposed to steep rocky terrain on solar aspects during the middle of the day.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Avalanche Problem 2: Storm Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Hot weather means cornice season, and this is the time when large mature cornices begin to fall off and the mountain sheds its snowpack. On ridges stay well away from cornices (they can reach back and get you), and avoid traveling under them.
Avalanche Summary
Poor visibility today - no avalanches noted. The local ski hills reported storm slabs running light but fast at all elevations and exposures..
Snowpack Summary
North aspect snow is soft, cold and well settled with few weak layers of concern. 20-30 cm of new snow is forming a soft slab, often on melt-freeze layers and will take a few days to bond. Expect more new snow and windslabs in the alpine by Friday morning
Weather Forecast
Cooling night time temperatures and continued light snow and clouds should help stabilize the surface problem fairly quickly.

The sun is strong right now and with this clear weather, it is destabilizing the snow on solar aspects in the afternoon. Generally these avalanches are running as loose wet and not stepping down to deeper layers, but the possibility remains.
