Since midnight, snowfall rates and wind speeds have increased, resulting in the formation of wind slabs in steep terrain at the high elevations. These slabs will increase in size and sensitivity today as they are further loaded by additional snowfall and sustained strong winds. By mid-morning pockets of slab could be triggered on steep wind loaded features near ridges and in cliffy terrain. At the mid and low elevations, the snowpack is stable and avalanche activity will be limited to small isolated events involving new snow in very steep terrain. Extra caution is advised as small slides can still carry severe consequences and during the COVID situation, any additional strain to the health care system should be avoided. There is no parking on Teton Pass today between Wilson Wyoming and the Idaho State line in advance of a planned 4pm road closure for avalanche mitigation. Grand Teton National Park is closed. Practice recommended protocols involving the COVID-19 pandemic such as social distancing at access points.
