Heavy snowfall and strong winds have created dangerous avalanche conditions in the Abajo Mountains. With more snow on the way, conditions will remain dangerous through the week.
Weather
SW winds will be on the increase today as the next system moves into the area. Looking like a repeat performance of yesterday's event, we should see snow starting this afternoon and continuing through Tuesday night with another foot or more looking likely. By Wednesday, the flow shifts to the NW, and we're starting to see signs of a transition away from the current weather pattern that has been characterized by atmospheric rivers and warm southwest flow. Nevertheless, unsettled weather and another chance for snow on Thursday finishes out the week.
Snowpack Summary and General Conditions
A foot or more of heavy, dense snow has fallen in the Abajo Mountaisn. The dense, new snow has formed a cohesive slab over the lower density, old snow surface, and this process was aided by sustained southerly winds that blew and drifted snow at all elevations. Unstable slabs of wind drifted snow up 18"deep exist on leeward slopes. The recent storm snow will be less sensitive today, but human triggered avalanches remain likely, especially on steep, wind loaded slopes with a northerly aspect.
The November persistent weak layer is deeply buried in most areas and is becoming harder to affect. Areas of concern include places where the snowpack is thinner like along slope margins, near rocky outcrops, or along steep convexities. We are once again testing it with a new load of snow and more is on the way. For now, let's steer clear of steep, northerly facing terrain until the dust settles so to speak.
