Stick to conservative terrain free from overhead hazard.
Avoid large, steep and open slopes at higher elevations where persistent weak layers are more triggerable.
Wind slabs can be found on all aspects, however fresh and reactive slabs will likely form on north facing slopes. Wind slabs will be most reactive where they overly surface hoar.
Surface hoar and facets buried in the upper snowpack have produced recent avalanche activity. Large loads or step-down avalanches may initiate avalanches on the February layer buried deeper in the snowpack.
On Monday, several naturally triggered persistent slab avalanches to size 2.5 were reported. Natural and rider-triggered wind slabs to size 2 were also reported on south-facing slopes.
Storm snow will accumulate over wind affected surfaces at higher elevations, with deeper deposits expected in north facing terrain features. Older wind slabs likely still linger below, found on all aspects. Lower elevations will receive a mix of rain and wet snow.
Two layers of concern currently exist in the upper-mid snowpack. Surface hoar on a crust can be found 20 to 60 cm deep. And a layer of facets, surface hoar and/or a crust from mid-February is buried 50 to 100 cm deep.
The remainder of the snowpack is well consolidated with no current concerns.
