GNFAC Avalanche Forecast for Sun Dec 9, 2018
<p>The snowpack in the Bridger, Gallatin and Madison Ranges, and mountains near Cooke City is 2-3 feet deep and generally stable without widespread buried weak layers. Near West Yellowstone, the snowpack is 1-2 feet deep, sugary and weak (<u><strong><a href="https://www.youtube.com/watch?v=hl5lygIF7s4&index=9&list=PLXu51…;). Check out our <strong><a href="https://www.youtube.com/playlist?list=PLXu5151nmAvRNl9kuY3DxfWN1qiU7IeX… videos</a></strong> and <u><strong><a href="https://www.mtavalanche.com/snowpits">snowpit profiles</a></strong></u> on our website for a snapshot of the snowpack structure across our advisory area.</p>
<p>Reports of avalanches last week were confined to small slides of new and wind-drifted snow (<u><strong><a href="https://www.mtavalanche.com/avalanche-activity">Avalanche Activity</a></strong></u>). Today will be the fifth day in a row without new snow or heavy wind-loading, and avalanches are unlikely to be triggered. On Friday, ice climbers in Hyalite triggered a small pocket of wind-drifted snow (<u><strong><a href="https://www.mtavalanche.com/images/18/ice-climber-triggered-small-wind-…;). Similar small wind slabs might be found today. Blowing and drifting snow or cracking of the snow surface are signs that you might find unstable fresh drifts. Assess wind-loaded slopes for the consequences of being caught in even a small slide. Today, the avalanche danger is rated <strong>LOW</strong>.</p>
