Highlights

Light snow and winds will build our wind slabs, but hopefully not to the point they become serious problem. If you're out and about, watch wind patterns to monitor slab development.

Avalanche Summary

Nothing today.

Snowpack Summary

Tree line and above is starting to see wind slabs become more prominent. The treeline/alpine border has small, isolated wind slabs likely caused by the terrain's localized influence on wind patterns. They are unreactive and appear to be well bonded to underlying layers; not much of a problem at the minute. Higher up in more open terrain the wind slabs are more specific in terms of distribution. Gullies and cross loaded areas with large fetches (snow fields that provide snow for wind transport) are likely places to find more consistent slabs. We aren't seeing any activity with these slabs, but they are there and will change character with additional load. The mid November crust is still giving us good travel up to 2350m and hasn't started to break down and cause problems.

Weather Summary

Sunday will see a slight warming trend and some incoming snow. Temps will rise progressively tomorrow from -9 to -7 by evening and continue to -6 overnight Sunday. Snow will be light, but continuous with a few centimeters tonight, and a few more over the day tomorrow. Treeline winds will be moderate (30-40 km/hr) from the SW.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
