Tetons

New snow and strong southwest winds have formed isolated pockets of new soft slab up to 18 inches deep in some mid and upper elevation avalanche paths. These new slabs could be human triggered in steep wind loaded avalanche starting zones and cliff areas. With strong winds and more snow in the forecast these slabs will increase in depth and size as the day progresses. Todays warming temperatures will contribute to the instability of these surface slabs by depositing warmer denser snow on top of colder lighter snow.
