Logan

The avalanche danger is MODERATE today. Strong winds and heavy snowfall are creating heightened conditions and human-triggered avalanches are possible, mainly in upper-elevation wind-drifted terrain facing northwest through southeast. Avoid overhanging cornices as they could break further back than expected and possibly cause an avalanche on the slope below.

Evaluate the snow and terrain carefully. Stay well back from cornice edges and off of slopes under overhanging cornices.

If we get the high end or more of forecast snow amounts, the danger could rise to CONSIDERABLE.

An observer noted a small, shallow slab avalanche in Woodcamp yesterday. No other avalanches were reported. Read about all avalanches and observations HERE.

Another winter storm for another bonus powder day! It's snowing in the mountains and the National Weather Service has issued a Winter Weather Advisory with heavy snowfall and strong winds expected for most of the day. Tony Grove picked up .4" of swe (3" of snow) overnight. There is great coverage in the Logan zone, and you'll find improving riding conditions throughout the day as snow accumulates. The biggest concern will be drifting by strong winds from the west. Avalanches of wind-drifted snow and large cornice falls are possible, mainly on slopes facing northwest through southeast. Mountain temperatures should stay below freezing, and hopefully, snowfall will continue throughout the day, though there is some uncertainty about total snow amounts. If we get the high end (10-14"), the avalanche danger may rise to CONSIDERABLE for a short period, but there is some sense that the storm is losing energy, and we may only see about 6-8" total.

*If the sun shines even briefly, it will moisten the snow surface and elevate the potential for loose wet (or moist) avalanches entraining recent snow on steep slopes.

The Tony Grove Snotel at 8400 feet reports 28°F this morning, with 102 inches of total snow (110% of normal SWE for the date). It's 24°F at the Card Canyon weather station at 8800 feet, with 79 inches of total snow. At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 20 to 30 mph from the west with gusts in the 40s mph, and it's 22°F. The winds on Paris Peak at 9500 feet are blowing 17 to 27 mph from the west-southwest, and it's 21° F.

Today will be a stormy day in the mountains, with periods of heavy snowfall and sustained strong winds blowing from the west. 8500' high temperatures will be around 32°F. Winds will blow 20 to 30 mph, with gusts in the 40s mph. The uncertainty lies in how much snow the storm will produce; high-end forecast amounts (10-14") may push the avalanche danger into the considerable range at upper elevations making natural avalanches possible, but, the models are only showing about .6" total swe today, which is about 6-8" of snow. Just be mindful that during any period of high precipitation intensity, the avalanche danger is increasing. High pressure builds in tomorrow for most of the work week along with unseasonably warm temperatures.
