Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Monday - March 14, 2016 - 7:27am
bottom line

Overall, the avalanche danger is generally LOW but strong west southwest winds may cause the danger to rise to MODERATE in upper elevation, wind exposed terrain where wind loading may cause slabs to form on the lee sides of ridge crests and terrain features.




special announcement

This advisory has been posted on Monday, March 14 and will provide a general danger rating with potential problems to be aware of for the upcoming week.

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

Spring like snow surfaces reign in the mountains with a variety of wind and sun crusts, as well as wind scoured snow surfaces above treeline. Some areas of settled powder remain on sheltered northerly aspects.

A storm system tracking through to the north will bring clouds and strong westerly winds through Tuesday. Little or no snow accumulation is expected but the severity of the winds may increase the avalanche danger. See detailed problems below.

description

In spite of the crusted over south and west facing slopes, strong west southwest winds will be able to move snow around as they etch into the snow surface. Be on the lookout for recently developed, shallow wind slabs on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain. Additionally, it may still be possible to trigger an isolated, but deeper wind slab that formed earlier in the week. Suspect smooth rounded pillows of drifted snow on steep, northerly aspects.

description

Much more the exception than the rule, it is still possible to trigger an avalanche on weak, sugary, faceted snow near the ground in isolated locations. Particularly if new wind slabs form over top off the underlying weak snow. You may encounter this problem on northerly aspects in areas of steep, rocky, radical terrain where the snowpack is shallow and weak. Slide paths that have been repeat runners during the season are also suspect.
