Tetons

The west side of the Tetons received 6 or more inches of new snow overnight while the east side accumulated two. Continued strong northeast winds have created easily triggered soft slabs to a foot in depth on lee slopes at upper elevations. The new snow rests on slick sun crusts or faceted snow depending on aspect. Rapidly warming temperatures will increase the chance of natural and human triggered wet surface slides that could grow to dangerous size at mid and upper elevations on sunlit slopes.

High pressure will build into the region keeping skies clear for cold mornings then rapidly warming temperatures. Monday morning mountain lows will be in the teens then rise into the upper thirties or warmer. Winds will be light and variable at the ridge tops.The general avalanche hazard in the Tetons will be Moderate where northeast winds blew the new snow into pockets of dense surface slabs to 18 inches in depth near ridge tops and across exposed ridges. The avalanche hazard will be Moderate in the Continental Divide/Togwotee Pass and Southwest Trails/Greys River areas due to the possibility for users to trigger full depth, hard-slab avalanches.Warming temperatures will make all avalanches more susceptible to triggers and create the chance of naturally released and human triggered wet-loose slides.
