current conditions A couple more feet of snow fell yesterday and overnight at upper elevations, and warming temperatures turned the nice powder from the week upside down. Before we lost contact at 7:00 last night, the Tony Grove Snotel reported 82 inches total with another foot of new snow and 2" of water in the last 24 hours. The snow is inverted, or heavier on top. Southwest winds picked up significantly yesterday and were cranking last night, with the 9700' CSI Logan Peak weather station reporting overnight average wind speeds of around 30 mph, with a 60 mph gust early this morning. Very dangerous avalanche conditions exist and you should avoid and stay well out from under all steep slopes and avalanche paths. This morning's 4km Water vapor imagery.

recent activity We recorded a total of 6 people being caught and carried by avalanches in the Wasatch backcountry during the week. The avalanches were apparently somewhat forgiving. Locally; I noticed a couple small triggered soft slabs as I was driving by the lower backside area yesterday evening. Natural avalanches from overnight are visible this morning in the Powder Mountain Area. Large and long-running natural avalanches ran down to Maple Bench and in other large avalanche paths on the east side of the Wellsville Range, and more natural activity is likely tonight and tomorrow. My video observation from Beaver Backside yesterday afternoon.....HERE

Dangerous soft slab conditions exist, and continued heavy snowfall and drifting will cause the danger to increase further and become more widespread. You are likely to trigger wind slab avalanches 2 to 3 feet deep, failing on weaker layers within the fresher snow or the sugary old snow surface from last week in steep drifted terrain, especially in upper elevation lee slope areas. Natural storm snow and wind slab avalanches are also likely in steep terrain today, tonight, and tomorrow..

The danger of persistent slab avalanches will continue to rise with the intensifying storm currently upon us. In areas where the preexisting snow is shallow it is very weak, and dangerous triggered persistent slab and/or deep slab avalanches failing on buried faceted weak layers are possible on some steep slopes. You could trigger avalanches remotely, from a distance or even from the flats below steep slopes. Large natural avalanches are likely this weekend, so stay clear of avalanche runout zones and out from under all steep slopes. The danger in some upper elevations areas could rise to EXTREME by this afternoon, and I would bet my sled that significant natural activity will occur overnight. Trent Meisenheimer released a great video last week about persistent slab avalanches. View it ...HERE

A rising rain/snow line today will further complicate the situation. Rain on all the fresh snow could create a significant danger of wet avalanches at lower elevations. Wet slabs and loose moist sluffs entraining significant amounts of fresh snow will become likely in steep terrain. Avoid terrain traps and the river below steep slopes and stay off of steep slopes where you might be swept into trees or rocks below. |

weather Expect dangerous avalanche conditions today and continued serious winter weather, with somewhat warmer temperatures, 8 to 12 inches of snow and sustained moderate southwest winds. 8500' temperatures will be around freezing, but warmer below.
