Tetons

At mid and high elevations, up to two feet of new snow and moderate westerly winds have created easily triggered soft slabs to four feet in depth on lee slopes. Four feet of new snow has fallen since Tuesday. Sloughs on all aspects have the potential to entrain large amounts of snow and run very far. The new snow has also increased the load on deeper, unstable hard-slabs that could pull out the entire snowpack. At low elevations pockets of soft slabs to two feet in depth and sloughs could rapidly build to dangerous depths in steep areas like road cuts and ravines. TRAVEL IN OR BELOW AVALANCHE TERRAIN IS NOT RECOMMENDED.

Occasional light snow is forecasted for Sunday night and Monday as some moisture from the northwest rides over a ridge to the west. Daytime mountain highs Monday will be near 20 degrees and ridge crest winds will be westerly to northwesterly at 20 miles per hour. Two to three inches of accumulation are expected for the Tetons and one inch for surrounding areas.The general avalanche hazard in the Tetons and Greys River areas is expected to be CONSIDERABLE Monday. Soft slabs to four feet deep from the newer snow and deeper, hard slabs could be triggered by backcountry travelers in steep areas. Most recent activity has had some common elements: Very steep slopes, good build-up of snow from ridge-crest winds or cliffs above and underlying faceted snow. Skiing conservative lines and careful route-finding are essential for safe travel in avalanche terrain.In the Togwotee Pass area, where less snow has fallen, the hazard is expected to remain MODERATE.
