Salt River and Wyoming Ranges

Human-triggered loose snow avalanches are possible on very steep slopes receiving direct sun. These slides are most likely in wind-sheltered terrain during the heat of the day. Triggering small avalanches of recent wind-drifted snow also remains possible at upper elevations. Exercise caution on slopes with recent drifting or snow that is starting to warm, particularly if entering consequential terrain, and continue to give cornices a wide berth.  

A QUICK SEASON RECAPAt this point in the season, some of us ask ourselves, "Where did the winter go?" while others ask, "Where is it dry enough to bike?" November is full of possibilities for the winter ahead; before we know it, it's over. If you want a quick trip down memory lane, read on.

This winter was divided into two very distinct halves. Weather remained primarily quiet while areas to our north and south—namely, Colorado and Montana—already had a stout snowpack by December. With a few small storms, things were looking promising. Things dried out considerably in January, creating a thick layer of near-surface facets, which were quickly buried by bigger, wet storms and remained relatively quiet. The second half of winter provided well. February was the month of no sun, with trickling storms creating a relatively deep and stable snowpack, and catching us up to average on depths. Right now, we're sitting at around 88-99 percent of average for snow-water equivalent for the year.  Of 127 issued forecasts, we averaged around 39 days of High & Considerable ratings in the Tetons, 44 in the Salt and Wyoming, 43 in the Snake, and 33 at Togwotee Pass, aligning with where areas saw greater snowfall during large storm cycles. Overall, a greater percentage of frequent, but small (less than D2) avalanches were noted in the Tetons, Snake, and Salt & Wyoming this season vs last. Notably, weak snow near the base of the snowpack at Togwotee Pass (par for the course) contributed to two very large human-triggered avalanches over the season, with the area harboring a low-probability but high-consequence scenario. 

Public observations accounted for 358 of 661 total observations. More data = more accurate forecasts and better information for you & your community to have a safe winter. THANK YOU!

Currently, keep in mind that it's still wintery in the alpine, and the transition to new snow forming wet snow problems will be fast. For a majority of the terrain in the forecast area, the snowpack is generally stable, and avalanches are unlikely. Use normal backcountry caution—make a plan before heading out, carry the appropriate avalanche safety equipment, and remain alert for unexpected conditions. Put in plain words—keep your wits about you! Thanks for a great season.
