Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Wednesday - March 16, 2016 - 6:50am
bottom line

Overall, the avalanche danger is generally LOW but unstable snow may exist on isolated terrain features in upper elevation, steep and radical terrain, that has a NW-N-SE aspect.




special announcement

This mid-week advisory provides general snow, avalanche and mountain weather information. More detailed information will be posted on Friday, March 18.

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

A storm system on Monday left trace amounts of snow and produced strong west southwest winds. Expect to find a mix of wind and sun damaged snow and possibly isolated, shallow wind slabs in upper elevation terrain.

description

Generally safe avalanche conditions exist in the La Sal Mountains. But as we like to remind you, low danger doesn't mean no danger. In fact, the definition of low danger says to watch for unstable snow on isolated terrain features.

Potential areas of unstable snow still include:

Wind Slabs: You may encounter isolated wind slabs on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain, primarily on slopes that have a NW-N-SE aspect. Mostly shallow, they could possibly knock you off your feet and sweep you over a cliff in areas of steep and more radical terrain.

Persistent Slab: Much more the exception than the rule, there are still areas of steep, rocky, and more radical terrain where it may be possible to trigger a persistent slab where the underlying snow is shallow, weak and faceted.

Continue to practice safe travel techniques and approach areas of steep, rocky, radical terrain with caution.
