Tetons

At mid and high elevations a storm dropping several feet of new snow ended Sunday with another foot over the past three days. Soft and hard slabs to five feet or more in depth are likely to be triggered today by backcountry travelers on steep avalanche terrain. Yesterday a two foot deep slide was skier released at the top of Milelong couloir (9,400 feet, north facing.) At low elevations pockets of soft slabs to two feet in depth could be triggered in steep areas like road cuts and ravines. Yesterday a two foot slab was released at 7,500 feet on the approach to Maverick in Grand Teton NP. Cautious route-finding and conservative decision making are essential for safe travel in avalanche terrain today.

The general avalanche hazard in the Tetons and Greys River areas is expected to be CONSIDERABLE Wednesday. Soft slabs to four feet deep from the newer snow and deeper, hard slabs could be triggered by backcountry travelers in steep areas. Periods of sunshine will put additional stress on the snow and make triggering slides easier. In the Togwotee Pass area and below 7,500 feet in the Tetons the hazard is expected to remain MODERATE. The chance of triggering hard slabs to three feet in depth is becoming more unpredictable.
