Tetons

The General Avalanche Hazard is MODERATE at Mid and Upper elevations and LOW at Low elevations. A foot of light density snow fell ending Tuesday morning accompanied by strong south to southwest winds. Soft slabs to eighteen inches deep may be triggered in lee areas near ridgecrests. Observed activity ran within the new snow layers. Frigid temperatures often make it more difficult to trigger slides and the second or later traveller on a slope may start a slide. At Low elevations the snowpack is shallow and slides are unlikely.

High pressure will keep temperatures cold again Wednesday night with lows ten to fifteen below zero. Highs will reach the teens Thursday. A series of weak disturbances will reach the area from the northwest out of Canada bringing a chance of light snow by Wednesday afternoon. Ridgetop winds will continue northwesterly at 15 to 20 mph.The General Avalanche Hazard for the Teton area will decline but remain in the MODERATE category for Upper and Mid elevations. Time and cold temperatures will reduce the hazard but pockets of soft slabs to eighteen inches in depth remain a concern on higher areas affected by more wind. Warming temperatures during the day Thursday will weaken the snowpack, perhaps enough for a traveller to trigger a slide. At Low elevations the Hazard will remain at LOW due to the shallowness of the snowpack.The General Avalanche Hazard will remain at LOW in the Togwotee Pass and Greys River regions.
