23-24

<p><span><span><span><span><span><span>Human triggered and natural avalanches are likely. Since Friday morning 2-3 feet of snow equal to 2.2” of </span></span></span></span></span></span><a href="https://avalanche.org/avalanche-encyclopedia/snowpack/snowpack-observat… water equivalent</span></span></u></span></span></span></span></span></a><span><span><span><span><span><span> (SWE) has fallen with a powerful storm happening this morning. Moderate to strong winds have drifted this snow into thicker slabs. Large avalanches breaking in the new snow are likely, and avalanches could break deeper and larger on weak layers at the bottom of the snowpack. Yesterday a skier triggered a 1-2’ deep slide in a steep chute north of Bridger (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31149"><span><span><span><strong><span…;). Avalanches will be deeper and wider today. Plan to stay out of avalanche terrain which includes slopes steeper than 30 degrees and flatter terrain below. Avalanche danger is HIGH.</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Near Big Sky, Hyalite, Cooke City, Island Park and West Yellowstone, 1-3 feet of dense snow fell since Thursday (2.1-3.2" SWE), and up to 3-5 feet fell over the last week favoring Island Park and Cooke CIty. Yesterday, we issued an avalanche warning for Island Park which expired this morning, and near Cooke City there were many large natural and rider triggered avalanches (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/avalanche-activity"><span><span><span><stro… activity log</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>, </span></span></span></span></span></span><a href="https://www.mtavalanche.com/photos?field_advisory_region_target_id=28&a… page</span></span></u></span></strong></span></span></span></a><span><span><span><span><span><span>). Riders watched an avalanche on Henderson Mtn. which broke 1000’ wide and ran far into the runout covering multiple fresh snowmobile tracks (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31157"><span><span><span><strong><span…;, </span></span></span></span></span></span><a href="https://www.mtavalanche.com/images/24/avalanche-henderson-mountain-3"><…;). Ian and I rode in Tepee Basin and saw two recent avalanches that broke 1-2 feet deep (</span></span></span></span></span></span><a href="https://www.youtube.com/watch?v=byHpBRxx8J8&amp;list=PLXu5151nmAvSH326z…;). Avalanches were also seen in the northern Gallatin Range (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31154"><span><span><span><strong><span…;, </span></span></span></span></span></span><a href="https://www.mtavalanche.com/images/24/rider-triggered-new-snow-slab-030…;), Bacon Rind (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31132"><span><span><span><strong><span…;), and Lionhead (</span></span></span></span></span></span><a href="https://www.mtavalanche.com/node/31112"><span><span><span><strong><span…;).</span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Today, large to very large avalanches can easily be triggered by skiers or riders. Natural avalanches are possible on slopes being loaded by wind-drifted snow. Avalanches could break beneath the new and wind-drifted snow, or over 3-6 feet deep on weak layers deeper in the snowpack. Dangerous avalanches conditions exist, and conservative terrain selection is essential. Plan to avoid steep slopes and runout zones below. Carefully evaluate terrain for the potential to avalanche. The avalanche danger is CONSIDERABLE.</span></span></span></span></span></span></p>
