More fear than harm with the storm, which finally brought some heat and left very little rain !
The cold, snow and wind are back for Friday, which will promote the formation of new small isolated wind slabs to watch out for in the alpine.

Snowpack Summary
The light rain and especially the mild temperatures have certainly affected the surface of the snowpack, which is showing a new melt-freeze crust that should be covered with a few centimeters of snow. Just below, 15 to 35 cm of snow covers the March 26 melt-freeze crust.
In the alpine and treeline, strong winds have redistributed these accumulations, forming an interface of soft and hard slabs that are upside down in some places.
The middle of the snowpack is well consolidated, and of increasing density, interspersed with several melt freeze crusts from the last few weeks.
