Natural avalanches are possible in drifted upper elevation terrain. People could trigger dangerous avalanches failing on a persistent weak layer buried near the ground, up to 3 feet deep, and soft slab avalanches of drifted storm snow are likely. Heightened avalanche conditions are found in most other terrain. We expect heightened avalanche conditions to continue to develop, particularly in drifted terrain, where people are likely to trigger soft slab avalanches of storm snow.

Periods of heavy snowfall are expected in the Bear River Range today, and strong winds from the west will continue to drift the new snow onto favored lee slopes. Temperatures continued to drop overnight, and webcams show moderate snowfall at Beaver Mountain's base and at UDOT's Logan Summit shed this morning. It's 25°F at the Tony Grove Snotel, with about 16 inches of new snow from the storm so far, and there's 42 inches of total snow at the site. The UAC Card Canyon weather station is showing a cool 21°F and around 15 inches of new snow, with 28 inches of total snow. On Logan Peak, it's 19°F, winds are from the west at 20 mph, with a gust of 44 mph early this morning. On Paris Peak, it's 18°F, and the wind is blowing from the southwest at 15 to 21 mph.

The National Weather Service has continued a Winter Weather Advisory for the Logan Zone through tonight. Expect periods of heavy snow in the mountains today, with 3 to 7 inches of additional accumulation possible by this evening in upper elevation terrain. Temperatures at 8500 feet will drop to around 16°F, and winds will blow from the west 20 to 25 mph, with gusts around 40 mph. Snowfall will taper off tonight, with temperatures around 5°F. Breezy conditions are expected, with wind from the west-northwest west 20 to 35 mph, decreasing gradually through the night. Tomorrow will be sunny, with a high near 17°F, with winds blowing from the west around 7 mph, and wind chill values as low as -7°F.
