19-20

<p>Snow depth is 1-3 feet throughout the advisory area. There is minimal evidence of widespread buried weak layers (<strong><a href="https://www.mtavalanche.com/snowpits">snowpits</a></strong&gt;), and avalanche activity has been mostly small slides confined to new snow (<strong><a href="https://www.mtavalanche.com/avalanche-activity">avalanche log</a></strong>). Aside from the couple inches of snow in Big Sky last night, the last snowfall was 4-6” five days ago (<strong><a href="https://www.mtavalanche.com/weather/wx-avalanche-log">weather log</a></strong>). Over the last couple days strong winds drifted recent snow into fresh slabs along ridgelines (<strong><a href="https://www.mtavalanche.com/sites/default/files/styles/very_large_1200w…;). Skiers in Hyalite found these fresh wind slabs which&nbsp;cracked easily under their skis, and they adjusted their plans to avoid terrain with big consequences (<strong><a href="https://www.mtavalanche.com/sites/default/files/styles/very_large_1200w…;). Avoid steep slopes with evidence of fresh wind-loading and be extra cautious of terrain where a slide can carry you into rocks, trees or over cliffs.</p>

<p>Where the snowpack is shallower, such as the mountains near West Yellowstone and the southern Madison and Gallatin ranges, there are weak layers of sugary facets on the ground (<strong><a href="https://www.youtube.com/watch?v=i6DWvLU0Eks&amp;list=PLXu5151nmAvSbcbVf…;, <strong><a href="https://www.mtavalanche.com/sites/default/files/styles/very_large_1200w…;). For now, these weak layers make larger avalanches a concern only on heavily wind-loaded, shady high elevation slopes (<strong><a href="https://www.mtavalanche.com/node/21027">photos</a></strong&gt;, <strong><a href="https://www.mtavalanche.com/sites/default/files/styles/very_large_1200w…;). When these mountains receive more snowfall, possibly later this week, the snowpack could become very unstable on all steep slopes.</p>
