Reactive wind slabs may build through the day on north through east aspects at upper elevations.
New snow accompanied by strong south winds may build fresh and reactive wind slabs on lee slopes at treeline and above.
Wet loose avalanches are possible where precipitation falls as rain at lower elevations.
Evidence of a widespread avalanche cycle up to size 3 was reported today. The cycle happened early this week.
New snow and wind on Thursday will likely build isolated, yet reactive wind slabs at upper elevations. Dry loose sluffing may exist in steep terrain features.
A rain-saturated upper snowpack exists to mountaintop. As freezing levels fall Thursday, a widespread crust will form at upper elevations, and lower elevations may continue to be wet with rain. New snow accompanied by strong south wind will likely build wind slabs at upper elevations. Expect deeper and more reactive deposits on north—and east-facing slopes.
A robust crust, formed in early March, can be found in the mid-pack. The snow above is well bonded to this crust.
Below this, the snowpack is well consolidated and strong.
