Avalanche Advisory
Advisory: Abajo Area Mountains Issued by Eric Trenbeath for Tuesday - February 6, 2018 - 7:32am
bottom line

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.

Episode 3 of the UAC podcast is live. We talk with UDOT Avalanche Program Supervisor Bill Nalli on how he and his teams keep the Greatest Snow on Earth from avalanching over the open roads and highways of the state. Check it out on ITunes, Stitcher, the UAC blog, or wherever you get your podcasts.

current conditions

Buckboard Flat is reporting 3" of new snow this morning and I would expect 5" or more up high. Not enough to turn winter around but every little but helps. Winds on Abajo Peak are averaging 20-25 mph from the WNW and it's 14 degrees up there.

Kevin Dressel was out and about on Saturday and reported his findings here.

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.

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.
