Highlights

Avalanche conditions are generally safe and large avalanches are unlikely at all elevations. Small avalanches, less than a foot deep, may be triggered on isolated wind loaded terrain features at the highest elevations. Watch for pockets of unstable wind drifted snow in very steep, upper elevation terrain and give cornices a wide buffer.

    The upper elevations of the Tetons received 4-6 inches of snow in the past 24 hours. Moderate winds out of the southwest and south have redistributed this snow and formed soft slabs less than a foot deep on isolated pieces of wind loaded terrain at the upper elevations. While the likelihood of triggering a fresh wind slab is on the low end of the scale today, skiers and riders still have the potential to trigger a small avalanche if venturing into very steep(>35°) terrain above 10,000’. Avalanches involving the newest snow will be small, but could catch someone off guard in consequential terrain. Be on the lookout for signs of wind loading and isolated pockets of unstable snow along upper elevation ridge lines, below cliffs, and in couloirs.

Avalanche Discussion

A passing storm brought a quick shot of snow to the Tetons yesterday morning with upper elevation terrain receiving around 6 inches of snow. Snow showers tapered mid day and most weather stations showed an inch or two of settlement by evening. Overnight snow totals ended up being less than expected with the mountains only receiving another inch or so. There were reports of small (D1) soft slabs around 10,000’ in GTNP, but little else in the way of avalanche activity. Another 2-4 inches of snow could fall today, yet this should do little to change the overall avalanche danger. Wet avalanche problems are not likely to be a concern today given the relatively cold and mostly cloudy conditions that are forecasted. Still, it is April (!) and any periods of prolonged sun could destabilize snow surfaces. Most slopes are stable and the danger rating will remain at Low today. Low danger does not mean no danger. Be on the lookout for isolated wind slabs if traveling to the highest elevations today.

Several bear sightings have been reported this spring. Bear spray, group travel, and appropriate food storage should be considered when planning the day. Also, please remember that closed ski areas are now uncontrolled and could have avalanche problems.  Keep this in mind if skinning up or skiing on very steep ski area runs.
