Go HERE for a list of UAC classes. |
current conditions It's mild and quite blustery in the mountains this morning in advance of a strong Pacific storm. The Tony Grove Snotel at 8400' reports 36°F and 26" total snow containing 83% of average SWE (Snow Water Equivalent). It's 29°F at the 9700' CSI Logan Peak weather station, and south winds picked up significantly overnight, currently blowing around 35 mph, and gusting to 58 mph. You'll need goggles today if you head up for opening day at Beaver Mountain, as snow is in the forecast all day. Snow and drifting from strong southwest and west winds will cause a rising avalanche danger in the backcountry, and dangerous conditions will develop on some slopes by evening.

description
An increase in south winds overnight created heightened wind slab avalanche conditions in exposed terrain this morning. Human triggered avalanches are possible in drifted upper and mid elevation terrain. The avalanche danger will rise and become more widespread during the day as a winter storm impacts the mountains and new snow stacks up on widespread weak preexisting snow. Drifting from strong southwest and westerly winds will rapidly build existing wind slabs and create new ones in exposed terrain. Dangerous wind slab avalanche conditions may develop by late afternoon, with human triggered avalanches becoming likely.

description
More than expected snow will cause a heightened danger of storm slab avalanches. We've noticed and observers report increasing instances of localized shallow collapses and cracking. Very weak surface snow is widespread across the Logan Zone, and a layer consisting of very weak faceted snow directly above the solid Thanksgiving crust appears to be gradually getting weaker.

weather The storm system over the Pacific Northwest will continue southeast into and then across Utah late this afternoon through Thursday. The associated cold front will enter northwest Utah this morning, then sweep southeast across the state by early Thursday. A second weather disturbance this weekend will bring additional cold air from Canada into the region.
