While the likelihood of triggering avalanches may be decreasing, the consequences if you do remain very high.

Avalanche Summary
No recent avalanche activity has been reported in the region.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
Roughly 40 to 50 cm of new snow continues to settle and bond over a weak layer buried just before Christmas. This layer consists of sugary faceted grains and/or small surface hoar and has been responsible for numerous large natural and human-triggered avalanches throughout the BC interior since December 27.
The mid and lower snowpack generally remains weak and facetted, with a number of weak layers present. A layer of particular concern that was buried in November, consists of weak facets, surface hoar, and/or a thin crust, and is roughly 90 to 140 cm down from the surface.
Snowpack depth is roughly 150 cm at treeline.
Weather Summary
Sunday night
Mainly cloudy, with no precipitation. Light southwest winds. -5 to -10 C at treeline.
Monday
A mix of sun and cloud, no precipitation. Light southwest winds. -5 to -10 C at treeline. Potential for a strong temperature inversion in the alpine.
Tuesday
A mix of sun and cloud, no precipitation. Light southwest winds. -5 to -10 C at treeline. Potential for a strong temperature inversion in the alpine.
Wednesday
Mainly cloudy, with flurries. Light southerly winds. -5 to -10 C at treeline.

Terrain and Travel Advice
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
- Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
Problems
Persistent Slabs
Several weak layers persist deep in the snowpack. Use extra caution where the snowpack varies from thick to thin, near rock outcrops and convexities. Larger-than-expected avalanches are possible due to the likelihood of avalanches stepping down to deeper weak layers.
Aspects: All aspects.
