Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Monday - March 21, 2016 - 6:50am
bottom line

Overall, the avalanche danger is generally LOW but unstable snow may exist on isolated terrain features. Remain on the lookout for isolated wind slabs on the lee sides of terrain features if you venture into extreme, upper elevation terrain.




special announcement

This advisory is based on field observations performed on Sunday, March 20 and will be updated next on Wednesday, March 23.

Please help guide our discussions of website maintenance, upgrades or possible changes in coming years. Take this brief survey. As a way of saying thanks we'll be raffling a free avalanche class and other free stuff like hats, beanies, water bottles, etc

current conditions

Looking down a south facing gully off Laurel Mountain with Mount Tukuhnikivatz in the distance.

It was quite a weekend in the La Sal Mountains with sunny skies and mostly stable snow. People were getting out and about and doing it all. On Sunday, I got up high in Gold Basin and saw numerous parties ascending Mount Tukuhnikivatz, as well dropping big lines off Tukno, into Talking Mountain Cirque, and into Horse Creek. Local observers also reported seeing a snowmoblile at close to 12,000' on the ridge above Middle Cirque on Saturday. In short, people are getting after it, and getting away with it.

Snow conditons on north facing aspects, though mostly stable, are quite variable having sustained a fair amount of wind damage over the past week. The real ticket right now is corn snow on SE-S-W aspects. For best conditions, drop just below treeline where the lack of wind has allowed for a great melt freeze cycle. With a change in the weather approaching, Monday will be your last day for this.

description

The avalanche danger is generally low at this time and people are getting into more extreme terrain without incident. However, unstable snow may still exist on isolated terrain features. If you are pushing it into more extreme terrain, particularly at upper elevations, on slopes that have a N-E aspect, remain on the lookout for isolated wind slabs, or areas where older persistent slabs may be resting on top of weak, sugary, faceted snow. Even a shallow slab release in these areas could produce a terrible ride with dire consequences.

weather

A high pressure ridge will continue to dominate the region through Monday. Southwest winds will increase ahaead of a Pacific storm system that will move in from the Great Basin on Tuesday. The brunt will affect mainly northern Utah and north central Colorado. We should see clouds Tuesday morning, with a chance of snow and wind continuing into Wednesday. We may see a stronger system in our area by the weekend.
