Tetons

The early season snowpack, which is comprised of faceted snow and crusts, is mostly stable and avalanches are unlikely.

A developing storm system is forecast to strengthen and dive southeast into the area with snowfall developing overnight. This system could bring three to six inches of new snow to the mountains and one to three inches to the valleys by Wednesday night. Temperatures will be in the teens and winds will be west veering to the north at 5 to 20 miles per hour. The new snow will accumulate on very unstable and slick old snow surfaces. Shallow loose snow sluffs are likely to occur on steep slopes at all elevations. At the upper elevations shallow pockets of new soft slab 6 to 12 inches deep could form in upper elevation avalanche starting zones and are expected to release naturally and be super sensitive to human triggers.The general avalanche hazard at all elevations will increase as the day progresses. It is expected to be LOW in the early morning hours and could rise to MODERATE at the upper elevations if the upper end of the forecasted snowfall amounts occur or are exceeded.
