A deep persistent weak layer remains in the snowpack, avoid thin rocky areas where triggering this layer will be more likely.
Prepare for challenging travel on a thick crust.
Two persistent weak layers are the main concern in the snowpack. One down ~30cm which, if triggered, could step down to the deeper layer (80-140cm) producing destructive slab avalanches. When there is a supportive crust on the surface, slab avalanches are less of a concern.
On Sunday a size 1 wind slab was reported near the summit of Mt Rogers. No other avalanches have been observed or reported in the Park for several days.
Expect a robust surface crust on all aspects below 1700m making for difficult travel. Above this elevation north facing slopes still hold up to 15cm of dry snow. A weak layer formed on March 9th is down ~30cm and the Feb 3rd persistent weak layer remains a concern at 80-140cm deep. The lower snowpack is well settled and strong.
An unsettled atmosphere will bring periods of light precipitation over the next few days and light to moderate winds.
Tues: Cloudy, possible flurries late in the day, alpine low -10 °C, light W winds, FZL 1600m.
Wed: Sun and cloud with flurries - trace of new snow, alpine low -11 °C moderate S winds, FZL 1600m.
Thurs: Cloudy with snow up to 7cm, alpine low -7 °C, light winds, FZL 1900m.
