Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Sunday - March 13, 2016 - 7:27am
bottom line

The avalanche danger is mostly LOW at this time. But low danger means that problems may still exist on isolated terrain features. You may still find isolated wind slabs, or deeper persistent slabs on steep, upper elevation, northerly aspects. If the sun stays out for an extended period, you will need to watch for loose wet slides on sun exposed slopes.

current conditions

Skies are clear this morning and overnight low temperatures have been in the low to mid 20's. Northwest winds on Pre Laurel Peak have dropped into the single digits. We should see clouds moving in later today as a storm sytem tracks through to the north.

A mixed bag of spring conditions exist of including breakable sun crusts, sloppy wet snow, and dry settled powder on sheltered, shady aspects. I did get a report yesterday from the intrepid Reed Kennard, of supportable corn snow on a sheltered, south facing slope just below treeline.

description

The avalanche danger is mostly low at this time. But low danger doesn't mean no danger, and problems may still exist on isolated terrain features. Here are a few problems to remain aware of:

Wind Slabs: Isolated wind slabs may still exist on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain, primarily on slopes with a N-NE-E aspect.

Persistent Slabs: It may still be possible to trigger a slab on weak sugary, faceted snow in areas of steep, rocky, and more extreme northerly facing terrain. Slide paths that are repeat runners are also suspect.

Loose Wet: If the sun comes out and slopes heat up, the danger remains for loose wet slide activity on sun exposed slopes.

weather

A storm system tracking to the north will bring us increasing cloudy skies today and a chance for snow tomorrow.

Today

Isolated snow showers after 5pm. Partly sunny, with a high near 29. Windy, with a north northwest wind 5 to 10 mph becoming southwest 20 to 30 mph. Winds could gust as high as 40 mph. Chance of precipitation is 10%.

Road Conditions: The road is a mix of dirt at lower elevations that turns to mud as the day progresses. It is snowpacked higher up.
