Avalanche Summary
We did see 1 cornice triggered slab on a sub-peak of Mt Lougheed. It pulled out the unsupported slope below it and then triggered another slope further down. It didn't appear to go on the deep persistent layer.
Snowpack Summary
The high alpine is experiencing stronger winds than expected. As expected, windslabs are a growing concern in the alpine. The question is are they reactive or not. We suspect yes- in certain places. Steep alpine slopes (35-40 degree plus) are suspect. The windslabs are also "laminated". Meaning that there are multiple slabs stacked up on each other with possible weaknesses between them. Open areas at treeline are less suspect as the winds haven't touched that area yet.
