description
Across the Logan Zone, wind slabs are forming today on weak preexisting snow. Heightened wind slab avalanche conditions already exist in exposed terrain at upper and mid elevations, and the danger will rise with continued snow and drifting from strong west winds. Dangerous conditions are likely to develop, with human triggered avalanches becoming likely on drifted upper elevation slopes.

description
As the fresh Christmas snow stacks up on slopes plagued by very weak sugary or faceted snow, storm snow avalanches will be possible even in sheltered areas. The problem is, slopes might be subject to gradual loading in the next several days, and the slow increase in danger is liable to catch people off-guard.

weather A series of weather systems will cross northern Utah this weekend into early next week.
