There's still a CONSIDERABLE (3) danger, and dangerous avalanche conditions exist in the backcountry around Logan. Triggered avalanches 1 to 3 feet deep are probable on upper and mid-elevation slopes approaching or steeper than about 35 degrees. In some areas, particularly in areas with shallow snow cover and where weak snow still plagues the basal layers of the snowpack, you might trigger a very dangerous deep slab avalanche. Although the recent instability is becoming less sensitive, you might still trigger some avalanches remotely or from below.....

Careful snowpack evaluation, cautious route-finding and conservative decision-making are essential for safe backcountry travel today.

The Tony Grove Snotel at 8400' a couple inches of new snow and .4 inches of water in the last 48 hours. This is stacked on top of an active surface hoar or frost layer formed early last week and preserved by light density snowfall . There's now 76" of total snow on the ground containing 70% of average water for the date. Its 18 degrees at the 9700' Campbell Scientific--Logan Peak weather station, and the wind is out of the north-northwest, averaging around 12 mph.

Yesterday was quite active in the Wasatch Range backcountry, with 15 or 20 reports of solar warming related and human triggered avalanches involving fresh snow accumulated over the last week failing on frost or surface hoar, which is widespread across the region.

Locally; numerous natural and easily or remote triggered avalanches reported across the forecast zone over the weekend....By far the vast majority of these avalanches involved the newest layer of snow picked up since a nice layer of surface hoar was covered and preserved by light snow on Wednesday 2-10-10. A couple more unintentionally triggered avalanches reported Monday, with a close call in Tab Hollow. A foot-deep soft slab avalanche broke 60 to 80 feet above a skier, who was able to self arrest on the bed surface, as the snow washed by.

Here's an updated local backcountry avalanche list:

Winds are moderate out of the north-northwest this morning. Mountain temperatures should stay fairly constant in the mid twenties today. Light snowfall will resume in the mountains this afternoon, as as a cold front begins to drop through Utah from the north. We'll likely see a decent shot of accumulation before tomorrow night, with around 6 inches forecast.

I will be issuing morning avalanche advisories for the Logan area on Mondays, Wednesdays, Fridays and Saturdays.
