bottom line Areas of CONSIDERABLE danger exist in the upper elevation wind drifted terrain. A MODERATE danger exists for mid elevation wind drifted terrain. These issues are more pronounced on steep north to east to south facing slopes and may still be triggered at a distance or break well above you. Safer, better options include wind sheltered mid-elevation slopes less steep than 35 degrees.

current conditions Keep your seat belt buckled: the weather pattern continues to look active through the week...and beyond. Skies are overcast with some light snow falling north of I-80. Winds have backed to the west and southwest and are blowing 15-20mph with gusts to 40. Temps are in the mid-20s. You'll find various wind and sun damage in the open, exposed and south facing terrain; respectively; however, we hunted out sheltered low angle terrain below treeline yesterday and were not disappointed. You won't be, either. Excellent photos of the wind drifted landscape can be found in Trent Meisenheimer's ob here. Greg Gagne has some excellent photos of cornices here. |

recent activity You might've guessed there'd be avalanche activity yesterday. Most had an easterly component and were heavily wind drifted from Saturday/Saturday night's strong west to northwest winds.

description
Lingering basal weaknesses from the pre-Christmas avalanche cycle and surface facets buried on the 14th comprise this avalanche problem. Stressed by the two feet of storm snow and strong west to northwest winds, these persistent repeaters showed their hand yesterday in upper Snake Creek and Rocky Point. The Eagle's Nest slide may have been last week's weak surface snow or Friday's low density snow - something that would support collapse failure/remote triggering. These repeaters have predominantly been on north to east facing slopes thought not confined to ridgelines and as low as 8500'. These may be more stubborn than yesterday but just as consequential. To enter this terrain, you've got to do the work: pull out the shovel, look at the snow structure, determine the instability and then gauge your risk tolerance. Otherwise, you're rolling the dice. |

Wind drifts were triggered on a variety of aspects and elevations yesterday. Remember that while the bulk of drifting sits in upper elevation north to east to south facing terrain, stronger winds can channel snow to off aspects well off the ridgeline. Skiers ski cut a 2' deep wind pocket on a southwest facing slope well off the ridgelines yesterday. These may still be sensitive to human weight as they sit on Friday's low density snow and in some cases faceted snow buried on the 14th. Give these smooth rounded drifts a wide berth and take clear note of collapsing and shooting cracks. Remotely triggered avalanches remain possible. Cornices have been growing leaps and bounds - give the exposed ridgelines wide berth until you know you're not on an overhanging wave of snow. These may break well behind you. |

Low elevation snow, particularly northerly aspects may be prone to some rain-on-snow events, such as what we may initially see this morning. The southerly aspects suffered some sun damage yesterday, but the northerly sheltered snow at the lower elevations may be more susceptible. Be mindful of your low elevation terrain traps and creek beds at these elevations... |

weather Snowfall should pick up throughout the day and into the evening where we may see 3-6" by tomorrow. Temps will be in the low 20s at 10,000', the upper 20s at 8000'. Winds will be southwesterly blowing 15-20mph, then veering to the west and northwest by afternoon. Other storms on the horizon include Tuesday night into Wednesday and again this weekend. Rapid warming and some clearing for Thursday/Friday. More info on our midday mountain weather forecast, found under on the Menu tab above. |
| general announcements Remember your information can save lives. If you see anything we should know about, please participate in the creation of our own community avalanche advisory by submitting snow and avalanche conditions. You can also call us at 801-524-5304, email by clicking HERE, or include #utavy in your tweet or Instagram. To get help in an emergency (to launch a rescue) in the Wasatch, call 911. Be prepared to give your GPS coordinates or the run name. Dispatchers have a copy of the Wasatch Backcountry Ski map. Backcountry Emergencies. It outlines your step-by-step method in the event of a winter backcountry incident. If you trigger an avalanche in the backcountry, but no one is hurt and you do not need assistance, please notify the nearest ski area dispatch to avoid a needless response by rescue teams. Thanks.
