Quick report

Cracking

Very exfoliating wind conditions. I bailed on my objective early but walked up the wind tunnel just to gauge the sensitivity of the forming slabs. Everything above the Meadows was wind-affected, making for challenging skinning on anything steep, but remained edgeable. These wind slabs will only get stiffer, and I estimate that they will remain sensitive after a drop in overnight temperatures and into tomorrow. Another hazard based on the terrain of your choice may be very firm riding conditions that would be unforgiving with a fall or if knocked off one's feet.  Monday will mark a distinct uptick in hazard: winds in the 50 mph range with incoming snowfall. This is not open season in the Tetons. You can certainly enter avalanche terrain currently with good margins. Still, in your brain, there should be the possibility of triggering wind-affected snow as well as a larger avalanche -like the one attached- noted on nearby Jackson Peak. The snowpack on Jackson Peak has remained as deep as the Tetons proper. Choosing terrain on north aspects not peppered with rocks, not shallow, and not overlapping with other avalanche problems (wind slabs, cornices, etc) is key.
