Tereza Turecka,
The avalanche hazard is expected to rise over the next couple of days. With limited early season observations and uncertainty in the amount of incoming precipitation, please approach avalanche terrain cautiously.For possible hwy closure info 511AB.
Summary
Weather Forecast

Snowpack Summary
25 cm of new snow at Parkers ridge in the past 24 hours with moderate to strong south west winds. Alpine and tree-line areas are slowly gaining enough snow for avalanches, particularly in leeward alpine bowls, gullies, and around ridge lines.
Avalanche Summary
No new avalanches have been observed by the road patrol on Saturday. There have been reports of smaller isolated wind slabs in alpine features over the past week, but not a lot of people are out in the mountains so take that into account in your decision making.
Confidence
Problems
Wind Slabs
Although still likely small, these avalanches could have severe consequences in extreme terrain or shallow areas. This avalanche problem is expected to increase with the incoming storm.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
Likelihood
Expected Size
Loose Dry
Ice climbers should use caution for overhead hazard during periods of heavy loading.
- Be careful of loose dry power sluffing in steep, confined or exposed terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
