Human triggered wind slabs remain possible. Use extra caution on north facing slopes at ridgeline.
Winter isn't over yet. Check out the new forecaster blog here.
Wind slabs may be possible to trigger on leeward slopes in the alpine. Back off if you encounter signs of instability like whumpfing, warming from the sun, shooting cracks or avalanches.
On Wednesday, several natural storm slabs (up to size 1.5) were reported on northerly aspects at treeline. Human triggered storm slabs also easily triggered (up to size 1) on west, north and east aspects at treeline and below.
The new snow reportedly has decent bond to the underlying crust. However, human-triggered wind slabs remain possible on northerly slopes at ridgelines.
Lingering wind slabs may exist on leeward slopes at treeline and in the alpine.
The past week brought 70 to 100 cm (deeper totals in leeward terrain) of recent storm snow, which sits above a crust that formed in early March. The recent snow reportedly has a good bond to the underlying crust. Steep solar slopes may see moist snow if the sun is out and refreeze overnight, forming a surface crust.
The mid and lower snowpack is strong and dense, with depths of near 400 cm at treeline elevations.
