40 cm or more of storm snow and wind have formed reactive slabs.
Human triggered avalanches are likely.
Buried weak layers from January and February could still be triggered, particularly at upper treeline and alpine elevations. Storm slab avalanches could step down to these layers, forming very large avalanches.
New snow and wind have formed reactive new slabs. Expect wind slab avalanches to be present on North through to east aspect terrain near or just below ridge crests.
Numerous natural and human-triggered avalanches continue to be reported. Large to very large (size 2 -3.5) both persistent and storm slab avalanches. Many of these avalanches occurred in the alpine and ran over 1000 m to the valley bottom. Extensive explosive avalanche control produced widespread large to very large (size 2-3.5) slab avalanches.
Large human-triggered avalanches continue to remain likely.
30 to 60 cm of new snow fell since Thursday. Moderate gusting to strong southwest winds have formed new wind slabs. Over the past 7 days, up to 100 cm of storm snow has accumulated and it overlies a hard melt-freeze crust and surface hoar crystals in wind-sheltered areas.
Weak layers of surface hoar and/or faceted grains, buried in mid-February and late January, are found 60 to 150 cm deep.
The lower half of the snowpack remains strong.
