There is LOW avalanche danger in the backcountry, and the snow is stable on most slopes. Areas of MODERATE danger may exist in drifted high terrain where shallow wind slab avalanches are possible. While unlikely, there is still some potential for people to trigger dangerous hard slab avalanches in upper and mid-elevation terrain steeper than 30°, where a persistent weak layer is buried around 3 feet deep. Small wet avalanches are possible at low elevations where last night's rain saturated the shallow snow.
Use normal caution, and continue to practice safe travel protocols.
While the likelihood of triggering an avalanche on a buried persistent weak layer is decreasing, the consequences of doing so are still significant. Although unlikely, large and dangerous avalanches failing on a buried persistent weak layer remain possible in upper and mid-elevation terrain on rocky slopes with shallow snow cover and on steep slopes below cornices.
Small wet avalanches are possible on steep, low elevation slopes where last night's rain fell on already saturated snow.

No new avalanches were reported over the weekend in the Logan Zone, but there were a few large natural avalanches and cornice falls last week. Read about all avalanches and observations HERE.
It's snowing in the mountains this morning. Another inch of new snow accumulated overnight in upper elevation terrain across the zone, while light rain fell at lower elevations. Today, we'll find mostly stable snow and decent dust-on-crust riding conditions, especially in low angled terrain where the refrozen snow is smooth underneath. More than expected snowfall and drifting today could elevate avalanche conditions at upper elevations where shallow avalanches of wind drifted snow are possible. Rain fell on the shallow snow at low elevations, and small wet avalanches may be possible on some steep slopes. Otherwise, the avalanche danger is LOW across the Logan Zone, meaning dangerous avalanches are generally unlikely. Even so, large and dangerous hard slab avalanches failing on a persistent weak layer buried 3 to 4 feet deep remain possible. There were a handful of large natural avalanches last week, some were triggered by large cornice falls, others possibly by rapid warming and heat shock. Our best travel advice is to stay off, away from, and out from under those large overhanging ridge-top cornices, and to continue to follow safe travel protocols by only exposing one person at a time to avalanche hazard while the rest of your party watches from a safer place.
The Tony Grove Snotel at 8400 feet reports another inch of new snow. It's 26° F, with 88 inches of total snow. It's 23° F at the Card Canyon weather station at 8800 feet, also with an inch of new snow, and there's 62 inches of total snow.
At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 16 to 25 mph from the northwest and it's 20° F. On Paris Peak at 9500 feet, it's 19° F, with winds blowing 9 to 16 mph from the north.
There's a chance of snow today, with about an inch of accumulation possible. It will be partly sunny with a high temperature around 31° F at 8500 feet. The wind will blow from the west 9 to 14 mph. Skies will be mostly cloudy tonight, with temperatures dropping to around 23° F and winds from the west-northwest blowing 8 to 13 mph. There's a 30% chance of snow tomorrow afternoon, but less than a half inch of accumulation is expected. It will be mostly cloudy with a high temperature around 35° F and 7 mph winds veering from the south in the afternoon.
Snow is expected and it could be heavy at times Wednesday night and Thursday, with 10 to 18 inches of accumulation possible by Thursday evening. Winds blowing from an easterly direction are expected as the snow falls, so we can expect unusual loading patterns.
