New snow accumulations have overloaded preexisting weak snow causing both natural and human triggered avalanches. There is a HIGH avalanche danger in the backcountry. More snow is expected throughout the day today and into Monday and this will keep the danger High. People without expert level snowpack assessment and backcountry travel skills are urged to stay out of the backcountry.

There is a HIGH (4) avalanche danger at upper elevations in the backcountry, and dangerous natural and human triggered avalanches are likely. Continued heavy snowfall and increasing winds will keep the danger level high throughout the day...

Dangerous avalanche conditions at upper and mid-elevations dictate that we stay away from and out from under steep slopes and obvious or historic avalanche paths today..

If we were to head out we might find rather heavy inverted new snow on top of nasty sugary facets....

Although a few parties did apparently drive up to the lake yesterday, you might not make it today.....Be prepared for full-on winter conditions and more incoming stormy weather. Driving conditions may deteriorate rapidly....

Might not be a bad time to get the sled out, but the snow is still real shallow and baseless off trail. Definitely not a good day for hill-climbing with a HIGH avalanche danger on snow covered upper elevation slopes…….Remember to slow down and watch out for pedestrians, especially in congested areas like Tony Grove.

I received reports of triggered soft slab and significant sluffs yesterday in steep terrain south of Tony Grove Lake…. Numerous reports of sensitive conditions, with both intentional and unintentionally triggered avalanches reported across the Utah Mountains yesterday.

Observers reported collapsing, cracking, wind loading, and avalanche activity yesterday... These are all bad signs...

Natural and human triggered avalanches are likely today as heavy snow and increasing winds pile onto slopes with very weak preexisting snow.

The National Weather Service has continued a Winter Storm Warning for our region through tomorrow morning.....Expect continuing heavy snowfall and increasing southwest winds today, tapering into tonight.....Expect the heaviest period of precipitation to occur early this afternoon....Snowfall should become showery overnight with diminishing west winds...Looks like a short lived high pressure will develop over the region Monday and Tuesday, but expect showery, on and off snow in our mountains.....

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