Heads-up! Rogers Pass had it's first major storm this past weekend and a large avalanche near Bruins Pass caught a few riders. Avalanche season is here, so slow down and carefully evaluate the terrain before jumping into it!

Summary

Weather Forecast

Monday and Tuesday should bring clear and relatively calm weather, with a storm developing Tuesday night. Freezing levels will remain below 1300m.

Snowpack Summary

A strong weekend storm has nearly doubled the snowpack depths at most elevations. The shallow snowpack is adjusting to this heavy, warm load and needs time to settle. Moderate to strong SW winds have created wind slabs in lee areas. Many rocks, stumps, and trees are still poking through the surface, so early season hazards still prevail.

Avalanche Summary

A human-triggered size 3 avalanche along Bruins Ridge caught two people, both of whom were lucky to escape with bumps and bruises. Dimensions of this slide were 50-100cm deep, 500m wide, and 700-900m in length. The slide covered the Video Pk uptrack. Partial burial of those involved. Several smaller size 1-2 slides reported near Balu Pass.

Problems

Wind Slabs

An icon showing Wind Slabs
Soft wind slab exists at alpine and tree-line elevations after the weekend storm. Touchy slabs partially buried a couple of people yesterday. These slabs are propagating wide and running quite long distances.
The new snow will require several days to settle and stabilize.Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: North, North East, East, South East.
