Ongoing strong winds are forming touchy wind slab conditions at higher elevations.
Ongoing moderate to strong northeast winds are forming wind slabs in exposed terrain at all aspects and elevations.
Several explosive-triggered wind slab avalanches up to size 1.5 were reported on Tuesday.
Recently formed wind slabs will almost certainly remain reactive to human triggers while the strong winds continue.
Recent snow continues to be redistributed by variable winds, forming fresh wind slabs throughout wind-exposed terrain.
A melt-freeze crust with facets above, exists down roughly 50 to 100 cm from the surface. This crust could be an excellent sliding surface for any avalanches triggered on the surface. We are closely monitoring this layer going forward as more snow accumulates it may become a persistent problem.
In general, we are not seeing the same basal weak layers that many of the neighboring regions are experiencing this season. However, may still see a problem develop as more snow accumulates and slab formation continues above it.
