Today, in the Logan Zone, people could trigger avalanches in the backcountry. Weak, sugary, or faceted snow from early November is widespread in upper-elevation terrain. Tuesday's snowfall probably overloaded some slopes with poor snow structure, causing elevated avalanche danger on upper-elevation slopes steeper than 30°. In exposed terrain, drifting built stiffer wind slabs on the underlying weak snow, and wind slab avalanches are possible. Although there may not be enough snow on many slopes to bury you, a ride over rocks in even a small avalanche could be quite dangerous.
- The 8500' Tony Grove Snotel reports 14°F and 22 inches of total snow on the ground. It's 13°F at the 8800' UAC Card Canyon weather station, with 24 inches of total snow.
- Currently at 9700' at the CSI Logan Peak weather station, it's 9°F and the wind is blowing from the west-northwest 25 mph, with gusts to 33 mph. The wind chill value is -11°F! At 9500' on UAC Paris Peak it's 9°F, and winds are from the west 16 to 20 mph.
- Today, expect mostly cloudy skies this morning, gradually becoming sunny. 8500' high temperatures will be around 20°F and winds will blow from the west around 3 to 6 mph.
Tonight, it will be partly cloudy, temperatures will drop to around 11°F, and winds from the west-southwest will blow 6 mph.
Tomorrow, it will be sunny. Expect high temperatures around 22°F and winds will blow from the west 6 to 10 mph.

A high-pressure system will continue to build over the area, and we can expect stable atmospheric conditions, fair weather in the mountains, and haze in the valleys for at least the next week.
Observers this week reported triggering a few audible collapses or "whumpfs" in generally north-facing terrain above around 8000' in elevation. These triggered collapses indicate unstable snow.
No significant avalanches have yet been reported in the Logan Zone, but there were several in areas that picked up more snow and wind earlier in the week.
This hard slab avalanche in the Uintas was remotely triggered by skiers near the ridge yesterday. Notice the wind deposited ash layer from the Yellow Lake Fire within the slab.
