Advisory: Moab Area Mountains | Issued by Eric Trenbeath for Thursday - November 26, 2015 - 7:32am |

current conditions There are lot's of things to be thankful for today even if this "storm" isn't one of them. We got wind out of this, enough so that it blew the propeller off the weather vane on Pre Laurel Peak. Winds yesterday blew in the 30-40 mph range with much higher gusts, and they switched around from S-SE-NE alternately scouring and depositing snow. In general, the snow surface is pretty worked over from the effects of wind, sun and warm temperatures. Settled powder conditions can still be found in sheltered areas but remember that it is still a shallow, early season snow pack and many obstacles such as stumps, rocks, and dead fall lurk beneath the surface. Base depth in Gold Basin: 29" Base depth at Geyser Pass Trailhead: 19" Winds, temperature and humidity on Pre-Laurel Peak New snow totals, temperature and humidity in Gold Basin Total snow depth and temperature at Geyser Pass Trailhead
Wind anyone?

recent activity Yesterday I did notice a few small, shallow, natural wind slab releases from under the rocks in the upper cirques off Gold Basin. |

description
Stiff, shallow, isolated wind slabs exist in exposed locations on the lee sides of terrain features. Difficult to trigger or even crack out, most are quite small and won't pose much of a problem. Areas of greater concern are on upper elevation, northerly aspects, down slope, well below the ridge crest,s and beneath rock bands where eddying wind currents have allowed more snow to be deposited. |

description
The danger for persistent slab avalanches is more a future concern at this time due to the development of persistent weak layers in the snowpack and the game now is to wait for a new snow load. Nevertheless, snow from the Nov. 10-11 storm, has consolidated into a cohesive layer on top of these weak layers, and it may still be possible to trigger an avalanche on slopes steeper than 35 degrees with a northerly aspect. |
