Tetons

Ten inches or more of new snow containing over an inch of moisture has been accompanied by strong west to southwest winds to create new slabs to three feet in depth on lee slopes. This new snow rests on a unstable snowpack that was already producing easily triggered slides to three feet in depth on many aspects. Easily triggered and naturally releasing slides are expected at the Mid and Upper elevations. TRAVEL IN AVALANCHE TERRAIN IS NOT RECOMMENDED. The snowpack is mostly stable below 7,500 feet but be aware of steep, isolated pockets where local wind and snow may have created a chance for human triggered slides.

An arctic air mass will bring bitterly cold temperatures to the region. Overnight lows will drop to near 20 below in the valleys and near 10 below on the summits. On Thursday skies will be mostly clear. Temperatures will rise into the single digits above zero. Winds will be light at 5 to 10 miles per hour from the north and northeast.Above an elevation of 7,500 feet the general avalanche hazard is expected to be CONSIDERABLE. Dangerous slab avalanches up to five feet in depth could be human triggered on a variety of aspects. Restraint and conservative terrain choices are essential for safe travel in avalanche terrain. At the lower elevations the general avalanche hazard is expected to be LOW. Avalanches are unlikely except in isolated pockets.
