Tetons
Pericolo valanghe
In sintesi
The General Avalanche Hazard is CONSIDERABLE at Upper elevations where dangerous slabs up to 4 feet in depth remain susceptible to human triggers mostly on northerly aspects. As the snowpack continues to stabilize, larger triggers may be necessary to initiate a slide, like two or more people on a slope at the same time or, a rider making just the right cut may weaken a previously tracked slope and cause a slide. At Mid elevations the Hazard is MODERATE. Potential dangerous slides are possible but less widespread. The Hazard is LOW at Low elevations due to thin snowcover and crusts.
Avalanche Discussion
The high pressure ridge will remain over the area Wednesday Night and Thursday with dry conditions, thermal inversions and light winds. The general avalanche hazard is expected to be CONSIDERABLE in the Greys River/Southwest Trails area and MODERATE in the Teton and Togwotee Pass/ Continental Divide areas. Unstable slabs up to four feet in depth persist especially on steep northerly aspects and in cliff areas. The slabs could release under the weight of humans, especially heavier triggers such as several skiers or a snowmachine or multiple snowmachines. On steep unstable slopes, a later single skier could trigger a dangerous slab by crossing a weak trigger point that earlier skiers on the same slope missed. Conservative choices are essential as the potential to trigger large deep slabs persist and consequences are severe. The general avalanche hazard below 7,500 feet is expected to be LOW.
