Tetons

At the upper elevations dense surface slabs to three feet in depth could be human triggered on steep, lee slopes near ridge tops or under cliff bands. At the mid elevations isolated pockets of surface slab up to 12 inches deep may be human triggered in very steep north facing starting zones. At the lower elevations travelers could release wet-loose slides in very steep areas as the day warms or slopes receive significant rain.

Heavy snow showers will continue into the early evening and gradually diminish overnight. Skies will be cloudy on Friday with periods of light snow likely into the afternoon. Winds are expected to veer to the west tonight and increase to 20 to 30 with gusts to 40 miles per hour. On Friday they will decrease to around 10 miles per hour by evening. Temperatures will be in the low teens to 20s at the higher elevations and in the 20s and 30s in the valleys. The new snow and strong west winds are expected to increase the general avalanche hazard at the upper elevations (9,000 to 10,500 feet) to CONSIDERABLE. Dense slabs up to three feet in depth lie upon a variety of crusts. On some steep avalanche prone slopes these slabs are likely to be easily triggered by the weight of a person. Natural releases are a possibility. At the mid elevations the general avalanche hazard may increase to MODERATE. Pockets of slab up to two feet in depth may have some potential to be human triggered in very steep avalanche starting zones. At the lower elevations the general avalanche hazard is expected to be LOW.
