Avalanche Summary
Several small skier triggered avalanches were reported in the Seymour backcountry. These avalanches were on north aspects and up to size 1.5. Check out the MIN report for more details.
Snowpack Summary
15 to 30 cm of new snow has fallen with southerly wind, forming wind slab on northerly aspects. In sheltered terrain this new snow may overlie soft, faceted snow or surface hoar. In exposed terrain it will overlie a sun crust or wind-affected snow.
A late-January weak layer (hard crust, facets, or surface hoar) is buried 80 to 120 cm deep, it is not currently a concern.
The lower snowpack is strong and bonded.

Terrain and Travel Advice
- Use ridges or ribs to avoid areas of wind-loaded snow.
- Seek out sheltered terrain where new snow hasn't been affected by wind.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
- Closely monitor how the new snow is bonding to the old surface.
Problems
Wind Slabs
Newly formed wind slabs will likely be found in exposed terrain. These slabs could be sensitive to rider traffic due to the weak layers underneath.
Aspects: North, North East, South West, West, North West.
