Tetons

At the upper elevations, skiers and riders might be able to trigger an isolated pocket of slab up to 18 inches deep on very steep, wind loaded slopes that have remained mostly dry over the last week. The snowpack is mostly stable at the mid and lower elevations. With temperatures starting out around five degrees warmer than yesterday morning, the chance for small wet slides might develop later in the morning if extended breaks in cloud cover occur. Grand Teton National Park is closed due to COVID 19. Practice social distancing, and keep in mind the extra burden to the healthcare community that a serious accident would create.

A Pacific system entering the area will bring snow from late tonight through Tuesday night. The heaviest snowfall will occur from midnight through Tuesday morning. Five to ten inches of snow could fall at the higher elevations by 5pm Tuesday. Temperatures are to be cooler with a high at 9000 feet near twenty degrees. Strong winds with 25 to 35 mph averages are to blow from the southwest in the morning and the west in the afternoon. The general avalanche danger will remain Low below 9000 feet where a stable snowpack exists and accumulations are to be on the lighter side. Above 9000 feet, the avalanche danger is expected to be Low in the morning and could increase to Moderate in the afternoon as new snow and wind form new wind slabs and add to existing wind slabs in very steep terrain. The amount of precipitation, the strength of the wind and the timing of both will determine if and when the danger increases to Moderate.
