Avalanche Summary
No new natural avalanches were reported lately. Keep sharing your observations via the MIN; it helps strengthen our information gathering.
Snowpack Summary
At 1900 m, the snowpack ranges between 30 and 90 cm. Near Joffre Lakes, the alpine terrain is wind scoured and bare. The latest snowfalls (15-25 cm) can be found sitting on a hard melt-freeze crust in most areas. In sheltered and shaded areas, surface hoar is growing at the surface due to cold temperatures. A thin snowpack is promoting the lack of cohesion in the basal snow.
Early season hazards are expected to stick around for the time being.
Weather Summary
An arctic ridge of high pressure will continue to be the main attraction. Conditions will be sunny and dry with a northerly flow pattern. The next frontal system is expected on Wednesday afternoon.
