Avalanche Summary
No new avalanches were reported on Sunday.
NOTE: Observations are currently very limited in this region.
Snowpack Summary
Most terrain has experienced significant melt-freeze conditions, though some northerly alpine slopes may still hold a few centimetres of dry snow.
While weak layers at the bottom or middle of the snowpack have been a concern throughout the season, the current lack of avalanche activity and benign weather suggest they are not a concern at this time. They could become problematic again this spring whenever temperatures rise significantly.

Terrain and Travel Advice
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- Carefully evaluate big and steep terrain features before committing to them.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
