Tetons

The General Avalanche Hazard is MODERATE at the mid and upper elevations where slabs to four feet in depth lie throughout avalanche country. Although not expected to release naturally today, these large dangerous slabs lie upon weak snow layers and could be triggered today by larger triggers or by a single person if he crosses over a hard to predict weak spot in the snowpack. Avalanches are not expected in the shallow snowpack at low elevations.

A weak system could deliver an inch of snow overnight tonight, followed by 2-4 inches in the mountains through Friday afternoon. The inversions are expected to break down, with highs temperatures Friday in the teens expected at all elevations.The general avalanche hazard is expected to be MODERATE throughout the region on Friday. Unstable slabs up to four feet in depth persist especially on steep northerly aspects and in cliff areas in the Teton area and on a variety of aspects in the Togwotee and Greys's area where they are underlain by a weaker snowpack. The potential exists for a lone skier or snowmobiler to trigger one of these slabs when a weak spot in the snowpack is crossed, even if the slope has several tracks already upon it. Larger triggers such as a snowmobile or group are even more likely to trigger such an event. These slabs should not be underestimated as they are large and carry severe consequences. Below 7500' the hazard is expected to be LOW.
