Get going early and avoid exposure to steep, sunny terrain being baked by direct sun. Wet loose avalanches have the potential to dig deeper as they move downslope, collecting a hefty mass that would ruin your day.




Avalanche Summary

Several loose, wet avalanches (sz 2-3) were observed on S'ly aspects Sunday, the largest being a deposit of wet, chunky debris on the Twins snowshed west of Rogers Pass. Frequent Flyer spit out a wet sz 2.5 midday Sunday

Deep persistent slabs are of concern, with a report of a cornice-triggered pocket high on Mt Smart failing to glacial ice, as well as a deep slab on Mt Fidelity. Also, the SW aspect at the top of 8812 Bowl/Bruins Ridge has reloaded on the basal crust, waiting for another release.

Snowpack Summary

Sun and warm afternoon temps have created a surface crust on solar aspects at all elevations, while N'ly slopes contain settled, dry powder (good, predictable riding).

Below this is a generally strong snowpack, however the basal weakness of rounding facets/decomposing crust near the ground should factor in to your terrain-use decisions.

Terrain and Travel Advice

  • Avoid sun exposed slopes, especially if snow surface is moist or wet.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
