Low Ratings but questionable riding conditions.
I find the lack of natural avalanche activity disturbing... strong winds have loaded lee areas but there is little evidence of a sensitive instability in the back-country. Play Cautiously.
Summary
Weather Forecast
A high pressure ridge to the west will fervently fend off any precipitation to the forecast region. For more details: Avalanche Canada's, Mountain Weather Forecast.
Snowpack Summary
Variable surfaces including temp/rain crust, hard wind press and loose snow sit above the November rain crust which may go as high as 2200m. Total snow pack height in alpine is around 45-85 cm. Wind pressed/scoured features to wind slabs in lee features in the high alpine. Cross loaded gulleys may threaten ice climbs from above.
Avalanche Summary
Previous strong winds transported old snow through the high alpine peaks and ridge tops. Hazard can be expected to increase in isolated areas where wind effect and loading is visible. No natural activity observed or reported in the forecast region.
Confidence
Problems
Wind Slabs
Widespread wind effect in the alpine at ridgetops and possible in open areas at treeline.
- Be careful with wind loaded pockets, especially in steep confined alpine terrain.
- Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: North, North East, East, West, North West.
