Recent weather has resulted in a high degree of variability across the region so be sure to verify avalanche conditions in your area as you travel and before committing to terrain.
Summary
Confidence
Avalanche Summary
On Sunday, several size 1-2 wind slabs were observed out of steep rocky north aspects around treeline in this great MIN report from Kitchener.
Snowpack Summary
In the north island, 20-40 cm of recent snow sits on a crust that likely extends into the alpine. (Check out this MIN report from Kitchener on Sunday.) Further south, the crust may be on the surface or lightly dusted by dry snow.
The mid and lower snowpack is generally uniform, with no significant layers of concern.
Below treeline, most areas are below threshold for avalanches.
Weather Summary

Partly cloudy with scattered flurries bringing a trace. 40 to 50 km/h northwest ridgetop wind. Treeline temperature -8 °C. Freezing level sea level.
Tuesday
Mostly cloudy with p to 5 cm of snow. 40 to 60 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

Terrain and Travel Advice
- Make observations and assess conditions continually as you travel.
- Investigate the bond of the recent snow before committing to your line.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Problems
Wind Slabs
In northern areas, recent snow may be poorly bonded to underlying surfaces. Slabs are likely be most reactive in wind loaded terrain features.
Aspects: North, North East, East, South East, North West.
