Points saillants

The answer to dealing with a complicated snowpack is to stick to easily solvable, moderate terrain and build confidence over time.

New snow on the horizon for the weekend!

    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.

    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.

Confidence

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

Weather Forecast

Unsettled weather as a series of Pacific fronts and lows begin to move inland bringing some light snow and fluctuating freezing levels initially. Winds ramp up on Wednesday with the approach of a heavy 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.
