North Rockies

New snow and wind will continue to promote wind slab development in high elevation terrain through the day Tuesday.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Wind slabs may be poorly bonded to the underlying crust.
• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

There have been no new reports of avalanche activity in the past few days

5-10 cm of snow may accumulate through Monday night and Tuesday at upper elevations. Expect southwest winds to redistribute this into alpine and treeline lee terrain. This may be sitting on a hard crust on all aspects to at least 1600 m. Below, the snowpack is generally settled and well bonded.
