There is a HIGH avalanche danger in the mountains around Logan. Dangerous avalanche conditions exist on upper and mid elevation slopes plagued by notoriously persistent buried weak layers. Triggered wind slab and storm snow avalanches are likely on slopes steeper than about 30 degrees, and natural avalanches are possible in steeper terrain. The danger of very dangerous, deep hard slab avalanches also increased with yesterday's new loading. Smaller storm snow or wind slab avalanches overrunning slopes with deeply buried weak layers could produce much larger avalanches...

We should avoid travel in avalanche terrain today and stay clear of the run-out zones of obvious or historic avalanche paths....

Looks like another stormy day in the mountains, and the National Weather Service has continued a Winter Storm Warning. through this afternoon. Yesterday's wind, warmth, and heavier snow created dangerous avalanche conditions in the backcountry for the weekend...

Southwest winds picked up significantly on New Years Eve, with 45 mph sustained hourly averages out of the west-southwest reported by the Campbell Scientific weather station on Logan Peak.

With a temperature of 25 degrees at 5:00 this morning, the Tony Grove Snotel reports 42 inches of total snow on the ground with 8/10ths of an inch of water accumulation in the last 24 hrs and 1.5 inches in the last 48 hours.

Saturday, snowmobilers remotely triggered a couple good sized avalanches from an adjacent slope in Providence Canyon near the warming hut under Providence Peak. The near miss occurred on a relatively small slope compared to many in the popular hill-climbing area, which remain mostly untracked.. (1-2-10 report)

On Friday a party in the Southern Bear River Range remotely triggered a wide hard slab avalanche on a southeast facing slope off an exposed ridge at a bit over 8000' in elevation...The 1'-3' deep avalanche reported was about as wide as a football field...I posted the report here

Its been about a week since a very wide avalanche occurred on Cornice Ridge over the Christmas Holiday. The 2'-6' deep by 1/4 mile? wide avalanche involved nearly the entire cirque....... I posted the avalanche report here.

Although the storm is mostly winding down, we're likely to see another good burst of storminess before its all said and done, with a few more inches of accumulation likely today....A dirty ridge will build into the region for the first part of next week, but small storms are likely to bring only the very Top of Utah a bit more weather in that time frame...

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