Be cautious on ridgecrests and roll overs. Up to 10 cm of new snow may bury recently formed wind slabs.
Seek out sheltered terrain for the best and safest riding.
Approach wind-loaded slopes on ridgecrests and roll overs with caution. Up to 10 cm of new snow could bury stiff wind slabs that could still be triggered by riders.
On Saturday, riders in the Mt. Washington backcountry observed wind-loaded snow at ridgetops up to 50 cm thick, which was cracking underfoot, suggesting reactive wind slabs may exist in these areas. Read the full details in this MIN report.
Looking forward to Monday, recently formed wind slabs in lee terrain features continue to be the main concern.
Up to 10 cm of new snow overlies 10 to 30 cm of recent storm snow, which was redistributed into wind slabs in exposed areas by strong westerly wind. This snow buried a thick crust on all aspects and elevations except high north. The crust may be on or near the surface on south and west slopes.
The remainder of the snowpack is moist to ground.
The snowpack depth at treeline ranges from 85 to 130 cm, there is very little snow below treeline.
