Logan

The snow is stable on most slopes in the backcountry, avalanches are unlikely, and the danger is LOW. Even so, people might trigger small wind slab or loose powder avalanches on slopes steeper than 30°. Loose avalanches entraining damp surface snow are possible in the middle of the day on sunny slopes.

• Use normal caution.

This week we observed a few small natural wind slab avalanches in drifted terrain, and observers report triggering loose powder avalanches on very steep slopes.

Last Saturday, skiers near Logan Peak in Mill Hollow remotely triggered a 8" deep and 60' wide wind slab avalanche that ran around 500 vrt'. Report is HERE

We've found fine cold powder conditions in the backcountry this week. The snow is generally stable, and the main avalanche concern is potential for small slab avalanches of wind drifted snow. Winds from the southwest increased a tick late last night, and people could encounter fresh drifts in windy terrain today. Winds were surprising calm, and we did not see much drifting in the past few days, so today's wind could find some powder to pick up and move around. Cold air temperatures are keeping the fresh powder nice for now, with the best conditions found in sheltered northerly facing terrain with soft snow underlying the fresh powder.

The Tony Grove Snotel reports 10" of new snow from Tuesday. It's 17° F this morning, and there is 97 inches of total snow, with 125% of normal SWE. The winds at the CSI weather station at 9700' on Logan Peak are from the southwest blowing 25 to 30 mph.

Today: Partly sunny, with a high near 20. Wind chill values as low as -5. West southwest wind 9 to 13 mph.

Tonight:Partly cloudy, with a low around 8. Wind chill values as low as -5. West wind around 10 mph.

Saturday: Increasing clouds, with a high near 23. Wind chill values as low as -1. West southwest wind 10 to 18 mph.

Expect sunny and continued cold weather heading into the weekend, with a chance of a bit of snow Saturday night and Sunday morning (4 to 7 inches possible). A productive storm looks to be developing for President's day and through much of next week, with significant accumulations possible state and possibly region wide.

We've found little evidence of recent drifting this week in the Central Bear River Range. Even along ridges with older cornices, the snow was soft powder with no sign of wind slabs. Great conditions, but there is plenty of soft snow that will easily be drifted into slabs when the winds increase. Photo of cornices and powder along the south ridge of Mt.
