Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Friday - February 13, 2015 - 7:29am
bottom line

The avalanche danger is generally LOW at this time but low danger doesn't mean no danger. With daytime heating the potential for wet slide activity exists on sun exposed slopes. There also remains an isolated possibility for triggering a buried persistent slab on steep shady aspects in more extreme upper elevation terrain, particularly in rocky areas that have a thin shallow snowpack.




current conditions

With warm sunny days and a mostly stable snowpack, conditions remain good for simply cruising around the mountains, enjoying the beautiful weather, and perhaps bagging a peak. In my travels yesterday I observed corn-like conditions on sun exposed aspects at mid elevations.Though conditions remain variable, settled, creamy, re-crystallized "powder" can be found on sheltered wooded slopes and on some upper elevation bowls. Elsewhere look for a variety of wind and sun crusts on exposed aspects. High elevation, wind exposed terrain has been scoured down to the rocks in some areas and some southerly aspects are melted out to the ground.

Ridge top winds overnight have been light from the NE picking up into the teens about 5:00 a.m. It is currently 32 degrees on Pre Laurel Peak though temps dipped to 29. It is currently 26 degrees in Gold Basin.

description

The avalanche danger is generally low at this time but as always, maintaining awareness of current and changing conditions is paramount for safety in the mountains and here are a couple of things to remain aware of.

Wet slides: Continued warm temperatures and sunny skies mean it will be important to remain on the lookout for sloppy snow conditions on sunny aspects. If signs of instability such as sloppy wet snow, pinwheels, or wet point releases present themselves, it means it is time to stay off of and out from under steep, sun exposed slopes.

Persistent Slab: In general we have reached a point where conditions are "weak but stable" and the chances of triggering a persistent slab are unlikely. Nevertheless, there still may be isolated areas where it is possible to trigger a persistent slab. Areas where you may find this problem are on upper-mid to upper elevation slopes steeper than 35 degrees that have a NW-N-E aspect, particularly in areas of rocky terrain that have a thin shallow snowpack. ​

weather

Warm, mostly sunny, spring-like conditions will continue through the weekend. A weak cold front will affect our area Monday into Tuesday bringing us a slight chance of snow and much colder temperatures. High pressure begins to build after that with a return to drier conditions later in the week.

Today: Sunny, with a high near 45. North northeast wind around 5 mph becoming northwest in the afternoon.

Tonight: Mostly clear, with a low around 27. North wind around 5 mph becoming south after midnight.

Saturday: Mostly sunny, with a high near 47. South wind 5 to 10 mph becoming west northwest in the afternoon.

Saturday Night: Mostly clear, with a low around 32. Northwest wind 10 to 15 mph.

Sunday: Sunny, with a high near 46. West northwest wind around 10 mph.

general announcements


Road Conditions: The road is packed and passable but also melting out and getting sloppy on the lower end.

Grooming Conditions: Trails are scheduled to be groomed Mondays and Fridays.

Observations: If you are out and about, I would love to know what you are seeing. Please post your observations here.
