{"blocks":[{"key":"cbntg","text":"Consistent reports of avalanches releasing on the February 22 surface hoar have been submitted over the past week. Human-triggered and remotely-triggered avalanches have been reported, even as professionals tiptoe around and avoid suspect terrain features. The problem is touchy but tricky. In many instances, slopes were ski cut with no results, only to have the third or fourth skier in the group trigger the slab. These avalanches have propagated widely across terrain features, warranting conservative terrain margins (see this MIN for a helpful example). Avalanche size has increased over the past several days, with more of the activity releasing size 2+. Observations extend to all aspects and elevations, but north to east aspects near treeline have been a hot-spot for reactivity. Avalanches are also occurring at unusually high elevations for surface hoar.

A few large (size 2) cornices were also observed failing naturally. If triggered, wind slabs and cornice falls could step down to the buried surface hoar layer, forming large avalanches. Use added caution on sun-exposed slopes when the sun is shining, as it could rapidly deteriorate the storm snow and cornices and cause loose or slab avalanches.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"9vq5i","text":"On Thursday, professionals reported large (size 2.5) explosive triggered avalanches releasing on weak layers near the ground.
