Tetons

Strong temperature inversions rebuilt overnight with the mountains starting out around 20 degrees warmer than the valleys. Backcountry travelers might be able to trigger an isolated pocket of slab up to a foot deep in very steep, avalanche prone terrain above 9,000 feet. While small, these slides have the potential of sweeping skiers and riders over cliff bands or into thinly covered terrain. Below 9,000 feet, avalanches are unlikely.

Tonight’s storm is to bring precipitation by 9pm. This system will be mostly finished by sunrise, with lingering snow showers and clearing skies expected on Tuesday. The storm will favor the Tetons where two to four inches is expected at the higher elevations. The other forecast areas are expected to receive closer to two inches of accumulation. Low elevations may see an inch. Temperatures during the day are to rise into the mid-teens at higher elevations the mid-twenties in the valleys. Winds are to be westerly overnight with averages above twenty miler per hour during the storm before decreasing and becoming northwesterly during the day. The general avalanche hazard will remain Low. The snowpack is stable and relatively shallow. New accumulations are to be too light to significantly increase hazard, however localized wind loaded pockets should be avoided as even small slides can sweep someone into rocky terrain.
