    Small amounts of new snow accompanied by SW winds Wednesday night may allow wind slabs to become slightly larger and potentially more reactive.

Confidence

Poor - Timing, track, or intensity of incoming weather system is uncertain

Avalanche Summary

A few small wind slab avalanches were reported from alpine features Tuesday.

Snowpack Summary

The upper snowpack is largely well settled and non-reactive.  Sun-exposed slopes and lower elevation areas are likely in a spring melt-freeze cycle. Weaknesses buried in the upper snowpack may include hard crusts and/or facet crystals, although not much is known about the reactivity or spatial distribution of this layer. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile.
