current conditions Snow. The Ogden mountains picked up another inch or two overnight, pushing storm totals since later Saturday to about a foot or so. Mountain temperatures are in the teens up high, 20F at 8000'. Don't let the light northerly winds this morning fool you - the northwesterlies blew 20-25mph at many locations for yesterday with mid-elevation anemometers showing gusty wind as well. |

recent activity Increasing winds yesterday stiffened up some of the new snow and fresh wind drifts moved with explosives and intentional ski cuts through the afternoon. (Photo: Wilson). Loose snow slides were common in the morning; some wind drifts were triggered on approach. And another thing - the US is up to 14 fatalities for the season, with 9 avalanche related deaths in the last 9 days alone. Some of these incident have been with very experienced backcountry folks. Something else that comes to mind when looking at the most recent 4 incidents below: in each of them, more than one person was caught and carried in the slide. The take-home here is to assess the terrain and put only one person on the slope - or even runout zones - at a time. 2015-2016
Airbags? My email to a guy asking about the full burial with airbag on the Gobbler's incident from Thursday -

I suspect by now, these drifts may be up to 2' deep and can pack a punch. It may be that one could get some of the blower powder moving as a sluff only to have it prod the overnight whales into moving as well. Ski cuts and cornice drops should give good indication of localized stability... but remember that these aren't for the faint of heart and can be at times dangerous at best.

Sluffs typically take a steeper slope angle to get moving (approaching 40° in steepness) and can certainly pack a punch in steep sustained terrain. In terrain like this, it'll be key to stay on sub-ridges and spines, or move diagonally across the fall line to avoid being taken out by your own sluff. By nature, they don't propagate laterally with initiation but they can sure reach what long-time avalanche worker Dave Medara calls "hovercraft mode". You'll know it when you see it. Click on the 'i' for more info on Loose Dry Snow (sluffs aka point releases). |

I gotta tell you - the snowpack is as complicated and complex as I've seen in a few years. Repeater avalanches. Persistent slab avalanches on southerly aspects. Persistent slabs down to 8500'. Doing the work and pulling out the shovel is key in assessing the snow structure - but how to get out into repeater terrain without putting oneself at risk? Rope?

weather We should be able to squeeze a few more instability flakes of snow out of the departing storm and transition toward mostly cloudy to partly cloudy skies. Temperatures should remain cold - we're looking at the low teens at 10,000', the low 20s at 8000'. Winds should remain light (10-15mph) from the north-northwest. Ridging will move in this afternoon through early Friday. Winds should remain generally light from the northwest over the next few days as 10,000' temps rise toward freezing by Wednesday. Models bring another series of storms through by late Friday. |
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.
