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

Advisory for the Moab Area Mountains

Issued by Eric Trenbeath for Tuesday, February 6, 2018 - 7:23am

The avalanche danger is MODERATE today and heightened avalanche conditions exist in steep, upper elevation terrain that faces NW-N-SE. Human triggered, persistent slab avalanches up to 2' deep, failing on weak, sugary, faceted snow at the ground are possible in these areas. The danger also exists for triggering a recently deposited wind slab in upper elevation, wind exposed terrain.

Weather and Snow


Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description

Areas of unstable snow exis on steep, NW-N-E facing slopes right around treeline and above where loose, weak, sugary faceted snow at the ground is providing an unstable base. The new snow will add some additonal stress to the ongoing persistent slab danger, and human triggered avalanches up to 2' deep are possible in these areas.

Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description

Today, be on the lookout for fresh wind drifts and wind slabs on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain. Look for smooth rounded pillows of recently deposited, wind drifted snow. A triggered wind slab also has the potential to step down creating a deeper and more dangerous persistent slab avalanche.
