Tetons

New snow and west to southwest winds have formed unstable soft surface slabs up to two feet in depth upon good sliding surfaces. These slabs will continue to gain depth and volume as the day progresses. Deep slab instabilities persist. These surface slabs are likely to be easily triggered by humans and release naturally from higher elevation avalanche starting zones. Very dangerous deep slabs also have potential to spontaneously release or be human triggered and run full track. Excellent avalanche skills are mandatory for safe travel in avalanche terrain.

Light density snowfall will continue through midnight and then start to taper off. Expect four to six inches of new snow by tomorrow morning. Mountain temperatures will fall into the single digits overnight before rising to near 10 on Monday. Southwest winds at 10 to 20 miles per hour should veer through north to the east by sunrise.The general avalanche hazard is expected to be CONSIDERABLE on Monday. One to two feet deep soft slabs, along with loose snow sluffs, could be triggered by backcountry travelers in steep, wind-loaded terrain. These avalanches have the potential to entrain significant volumes of new snow, and could sweep skiers or riders into terrain traps or over cliff bands. Deeper instabilities persist, especially in the Greys River area; if triggered these avalanches could run full track.
