A poor overnight refreeze and light rain will continue to break down the robust surface crust.
Avoid exposure to overhead hazards where the surface is soft, wet snow.

Avoid exposure to overhead hazards where the surface crust is fully broken down into soft wet snow.
Two human triggered wind slabs were reported on Thursday, just east of the region. These were both on northerly facing alpine slopes above 2500 m.
A few small (size 1) wet loose avalanches were reported on Wednesday that were triggered by skiers on sun-exposed slopes.
There is a widespread melt-freeze crust on most aspects. With a poor overnight freeze below 2500 m expected Friday night, and light rain forecasted for Saturday, the crust is expected to be less supportive over the weekend.
Up to 10 cm of dry snow overlies a crust in northerly alpine terrain.
The late March crusts are buried 20 to 80 cm deep, elevation and aspect dependent.
The mid and lower snowpack is well settled and strong.
