GNFAC Avalanche Forecast for Thu Nov 19, 2020

Snowpack and Avalanche Discussion

<p>The mountains throughout our advisory area have a layered snowpack, and avalanches can be triggered on steep slopes. Strong winds drifted last night’s snow into slabs which will continue to grow with strong west-southwest wind today and tomorrow.</p>

<p>Identify and avoid fresh drifts on steep slopes. Expect to find these drifts along ridgelines. Look for signs such as round pillows of snow and feel for relatively hard or hollow slabs. Photos from last week of a skier triggered avalanche (<a href="https://www.mtavalanche.com/images/20/wind-slab-n-bridgers"><strong>pho…;) and cracking drifts (<strong><a href="https://www.mtavalanche.com/images/20/skier-triggered-hard-wind-slabs-n…;) are examples of what you might see today and this weekend. Stay diligent with snowpack stability assessment and safe travel protocols through the weekend. If you do ski or ride on steep slopes, assess the consequences of a slide and minimize exposure to trees, cliffs, bare rocks and confined gullies.</p>

<p>Before you go out make sure that all your avalanche rescue gear is in good condition, and practice using it. Watch Dave’s early season videos for tips on checking your gear (<strong><a href="https://www.youtube.com/watch?v=Izkv4IIUmbk&amp;list=PLXu5151nmAvQDzKmH…;) and practicing with your beacon (<a href="https://youtu.be/p1xuaaSq4YU"><strong>video</strong></a&gt;). For more on early season snow conditions you can watch Doug’s 1-hour lecture from a couple weeks ago <a href="https://youtu.be/vyKdBBzd5IE"><strong>here</strong></a>.</p&gt;

Upcoming Avalanche Education and Events

See our education calendar for an up to date list of all local classes. Here are a few select upcoming events and opportunities to check out:

Hyalite

Date

Soggy up there today. Light rain to 9000 ft progressed to snow that stuck at roughly 8000ft. Only 1cm accumulation at that elevation, estimate 3-5 cm above 9k. No avalanche activity observed.
