Snowpack Summary
Approximately 5 cm of snow was received since Thursday evening in the Murdochville forecast area. This snow and the snow that was still available in some places was transported by the extreme west wind. This may have resulted in the formation of new wind slabs, especially in the NE-E-SE oriented forest openings. These harder snow pillows may be underlain by less dense snow or older wind slabs. The height of snow on the ground varies from 100 to 140 cm.
