On Monday, there were reports of naturally triggered size 2 cornices, size 1.5 wet loose avalanches on solar aspects and a skier triggered size 1 wind slab on a northeast aspect in the alpine.

Up to 25 cm dry soft snow can be found on shaded aspects above around 1500 m. On south-facing slopes and at lower elevations expect crusty snow in the morning and soft moist snow in the afternoon. Winds have slackened off of late, but recent wind slabs and cornices still pose a hazard close to steep ridgelines.

The lower snowpack has strengthened over the past week as previous persistent weak layers have become mostly unreactive. The main layers that we had been tracking are a layer of facets that was buried in mid-February (50-100 cm deep) and a layer of surface hoar and/or a crust that was buried in late January (80-120 cm deep).

• Wind slabs may be poorly bonded to the underlying crust.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
• Caution around slopes that are exposed to cornices overhead.
