11th Annual Utah Snow & Avalanche Workshop Open and Motorized Sessions Oct. 27th.

Advisory for the Abajo Area Mountains

Issued by Eric Trenbeath for Tuesday, February 6, 2018 - 7:32am

There is an isolated or MODERATE avalanche danger on steep, upper elevation northerly facing slopes where more than about a foot of snow can be found overlying weak, sugary snow on the ground. Also be on the lookout for shallow, recently deposited wind slabs in upper elevation, wind exposed terrain. Elsewhere the avalanche danger is generally LOW.

Description

Though isolated, a persistent slab danger still exists on steep, NW-N-E facing slopes above about 10,500 feet where more than about 16" of snow can be found on top of weak, sugary, faceted snow at the ground. Kevin Dressler was out over the weekend and reported collapsing and cracking in the snowpack in these areas - telltale signs of unstable snow.

Avalanche Problem #3
Wind Drifted Snow

Description

Today you may find some shallow new wind slabs on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain. They shouldn't pose too much of a threat, but it's always good to heighten your awareness when these things are present. Look for recently deposited wind drifts and cracking in the snow surface.
