Moab

Today the avalanche danger is LOW.

Low danger does not mean NO danger, so don't let your guard down. Although unlikely, I think you could still trigger a small slide up to a foot deep on isolated slopes facing NW, N, NE, and E near and above treeline.

Road Conditions: The Geyser Pass Road to the winter trailhead is plowed and mostly dirt and mud.

Grooming: Trails were groomed yesterday by LUNA.

Eric discovered this slide on Wednesday triggered by a snowbike which highlights a weak layer near the top of the snowpack near Colorado Bowl on the east side of Geyser Pass (NE, 10,800') . This slope had a soft slab of wind drifted snow on top of a faceted layer.

Weather

Today will be another stunning day for the La Sals but a bit warmer with temperatures getting into the upper 30s F. Temperatures this morning are starting 6-10 degrees warmer than yesterday. Winds should shift direction and blow from the SW with an approaching storm system. The jetstream will line up over the Utah/Arizona stateline early this coming week and bringing increased winds from the SW with snow likely starting Tuesday night. As the storm progresses, it looks like a "closed low" forms and stalls over southern California sending more moisture into the Four Corners region through the end of the week, and then skies clear by next weekend. It's too early to make a solid prediction on snowfall but fingers crossed.

General Conditions

The 3 inches of new snow late Thursday really improved conditions and people took advantage yesterday getting into alpine terrain. A persistent weak layer of old snow from Dec/Nov has become dormant as the last avalanches on this layer were about a month ago. Over the last four weeks, five storms have delivered snow with about 2" of SWE combined with a major wind event last weekend.

The weakest layer in the snowpack that caught my attention in Corkscrew Glades on Friday is a layer of obvious facets near the surface. We suspect it formed after last weekend's wind event and may be on most northerly facing slopes now capped by recent snow. A similar layer (or maybe the same layer) caused a slide on Wednesday, see below. One regular observer reported a few collapses yesterday on this layer near treeline where winds had drifted just a little snow.
