Lo esencial

When dealing with a complicated snowpack stick to easily solvable, moderate terrain and build confidence over time. This advice will be even more important when snow arrives on Friday.

    Continued building of new windslabs through the region. Most prominent on N through E aspects due to SW winds but riders should be wary of obvious wind effect and surface clues on all exposed or potentially cross-loaded slopes at treeline and above.

  • Deep Persistent Slabs

    This is a complex problem. The spacial variability and potential consequences of triggering a large avalanche on this layer makes it extremely difficult to gain confidence in the snowpack. Consider this before entering bigger features.

Weather Forecast

Unsettled weather continues bringing some light snow and fluctuating freezing levels.  Winds ramp up on Wednesday with the approach of a storm system.

Snowpack Summary

The snowpack is highly variable across the forecast region but remains mainly facetted, particularly in shallow areas. There is inconsistent bridging in the mid-pack over the weak basal facets and depth hoar.

Avalanche Summary

No new avalanches observed or reported.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Friday
