24-25

<p><span><span><span>Dangerous avalanche conditions exist across the advisory area. New and wind-drifted snow are loading weak layers buried 1-2 feet deep and human-triggered avalanches are likely. Reduce or eliminate exposure to slopes steeper than 30 degrees until the snowpack has time to adjust to recent snowfall. Traveling in and around avalanche terrain requires careful snowpack evaluation, cautious route-finding and conservative decision-making.</span></span></span></p>

<p><span><span><span><strong>Wind slab avalanches </strong>failing 1-3 feet deep are likely today. Avoid slopes with visual clues of recent drifting and commonly wind-loaded areas near ridgelines, below cornices and in gullies. Indicators of wind slab instability include recent avalanche activity, shooting cracks and a stiffening of the snow surface. Yesterday, my partner and I visited the site of a wind slab avalanche in Cooke City that broke 3 feet deep and 100 feet wide on Sunday as a group skied past (<a href="https://youtube.com/shorts/npOK4d94H50"><strong><span>video</span></str…;). Recent snow and wind had reloaded the slope, and it was ready to avalanche again. Expect a similar story throughout the advisory area. </span></span></span></p>

<p><span><span><span>On Sunday, riders in the West Yellowstone and Island Park areas reported <strong>persistent slab avalanches </strong>failing on buried weak layers near Two Top (<a href="https://www.mtavalanche.com/node/32430"><strong><span>details and photos</span></strong></a>), and a group on Mount Blackmore triggered a large <em>whumphing </em>collapse (<a href="https://www.mtavalanche.com/node/32443"><strong><span>details</span></s…;). Weak layers buried 1-2 feet deep exist across the forecast area (<a href="https://youtube.com/shorts/CdNOdERCQgc"><strong><span>Cooke City</span></strong></a>, <a href="https://www.youtube.com/watch?v=wDsq1f-KVUg&amp;list=PLXu5151nmAvToI_ir… Ridge</span></strong></a><strong>, </strong><a href="https://www.youtube.com/watch?v=CCd4OIw-4IU&amp;list=PLXu5151nmAvToI_ir… Fork videos</span></strong></a>). Recent avalanche activity, whumphs, and shooting cracks are bullseye indicators of instability. </span></span></span></p>
