The avalanche warning continues for all the mountains of northern Utah. Deadly human triggered avalanches continue to be very likely on steeper slopes. Avalanches can be triggered from a distance, so stay out from underneath steep slopes as well. People without expert level avalanche skills are urged to stay out of the backcountry.

Come join local avalanche forecaster Toby Weed for a one evening, one field day avalanche awareness class specifically for snowmobilers. The class will cover avalanche rescue skills, terrain analysis, danger rating interpretation, safe travel techniques, as well as the basics of avalanche awareness. Thursday evening (1-26) will be a 2 hour classroom session. Saturday (1-28) will be a field day in the Tony Grove area. Please call 757-2794 for more info or to register please visit the education link on our website....

Three or four feet of very heavy new snow since Wednesday morning, containing up to 8 inches of water, fell on very weak preexisting snow accompanied by sustained westerly winds. The heavy snowfall and strong winds created a lingering level 4 or High danger on upper and mid elevation slopes in the backcountry. Very dangerous avalanche conditions exist across the zone, and large potentially deadly triggered persistent slab avalanches remain likely on steep slopes. You should continue to avoid travel in backcountry avalanche terrain, and stay off of and out from under all steep slopes, especially obvious or historic avalanche paths that haven't already avalanched recently ...

With several feet of new snow and strong westerly winds late last week and over the weekend, the fragile preexisting snow was overloaded to the point of failure, and many large natural avalanches occurred in the mountains around Logan. I do not expect natural avalanches today, but the snow is still quite sensitive as evidenced by numerous collapses and extensive cracking in lower angle terrain. It is still very likely that you would trigger large avalanches if you were to venture onto steep slopes that didn't already avalanche. You should continue to avoid backcountry avalanche terrain for a while.

It's 19 degrees up at the 8400' Tony Grove Snotel this morning, and there is 77 inches of total snow on the ground containing 85% of average water for the date. The station picked up an amazing 8 inches of water between Wednesday the 18th and Saturday evening, the 21st. The CSI Logan Peak weather station at 9700' reports 14 degrees and south winds averaging around 17 mph...

A couple large and extensive natural avalanche cycles occurred in the Logan Area Thursday and Saturday nights, and there were hundreds of large avalanches on steep slopes across the zone and the mountains of Northern Utah. Several avalanches locally were triggered in terrain where avalanches are not all that common and on fairly low angled slopes, and thankfully no one was caught.... While many many slopes avalanched already in the last couple days, many did not. Many of these sit in a delicate balance just waiting for someone to come along and be a trigger.

The next splitting Pacific storm will impact the region today and tonight, and 4 to 8 inches of accumulation is possible in our area with more stormy conditions expected well to our south. Expect moderate south-southwest winds and high temperatures around 24 degrees today, dropping into the teens tonight. A mild westerly flow will set up over the region, bringing increasing chances for snow to the Logan Zone later on in the week... Another cold front (storm) is expected near the end of the work week but models diverge on it's potency...
