Unseasonably warm temperatures have caused heightened wet avalanche conditions in the backcountry. MODERATE avalanche danger exists at all elevations, with natural and human triggered wet avalanches possible. Also, people still might trigger shallow slab avalanches failing on a buried persistent weak layer, cornice falls, or loose dry avalanches entraining sugary faceted snow in very steep shady terrain. Evaluate snow and terrain carefully.

Finally, much needed snow is on the way! Good news, but with widespread layers of very weak snow at all elevations, expect rising avalanche danger in the backcountry this weekend.

An observer noticed a couple recent loose wet avalanches the ran off the Cutler Headwall in the Ogden Mountains.

Despite rapid warming, no wet or other avalanche activity has been reported in the last few days. People triggered a few small wind slab avalanches on drifted slopes in the Logan Zone last week, even though we only picked up a few inches of new snow.

Last week, a rider was caught and carried a short distance and his sled overturned in this small avalanche of wind drifted snow.

Way too warm temperatures in the mountains again will cause heightened avalanche conditions in the backcountry today. The 8400' Tony Grove Snotel reports 40°F this morning, and there is 60 inches of total snow at the site, with 84% of normal SWE for the date. Winds out of the south are blowing about 25 mph at the 9700' CSI Logan Peak weather station. The early March heat is delivering quite a devastating hit to our snowpack, and the surface of the snow even up high in shady terrain was getting a bit moist yesterday. As you might expect after a very dry February, backcountry snow conditions are quite variable. The extra warm temperatures are softening once supportable surface crusts, making travel difficult because you sink into bottomless loose sugary snow. Sunny low and mid elevation slopes are burning off quickly, especially on the "front side" or the western slopes of the Bear River Range.

Finally it looks like a significant change in the weather pattern. The first half of March will be a return to winter and snow is expected in the Logan Zone this weekend and next week. With widespread shallowly buried persistent weak layers plaguing terrain facing the northern half of the compass at all elevations, the avalanche danger rise significantly in the backcountry. Dangerous avalanche conditions will likely develop this weekend.

• Expect cloudy skies and snow showers in the mountains today, and the last day in a string of day with very warm temperatures. 8500' high temperatures will be around 40°F, with 15 mph west-southwest winds, and 1 or 2 inches of accumulation is possible.
• It will be mostly cloudy tonight and snow showers are likely, with 1 to 3 inches of accumulation possible. Temperatures will drop to around 21°F, with 10 to 15 mph west winds.
• Snow is likely tomorrow and tomorrow night, with 6 to 10 inches of additional accumulation possible by early Sunday morning. Expect high temperatures tomorrow around 32°F, and 7 to 11 mph west winds, veering from the south in the afternoon. Temperatures will drop to around 13°F and southwest winds will increase a bit on Saturday night.
• Dangerous avalanche conditions are fairly likely on Sunday, with continued snow accumulations in the mountains. Looks like perhaps a break in the weather on Monday, but unsettled, wintry weather will continue next week. The next storm could begin to impact the zone on Tuesday.

• Now is a great time to practice your avalanche rescue skills. Thanks to the generous support of Northstar, the Franklin Basin Beacon Training Park is up and running. The park is located directly west of the parking lot and is open for anyone to use. All you need is your beacon and probe. Please do not dig up the transmitters.
• Always follow safe backcountry travel protocols. Go one person at a time in avalanche terrain, while the rest of your party watches from a safe area. (practice anytime while traveling on or under backcountry slopes steeper than 30°)
• Check your avalanche rescue equipment, change your batteries, and practice often with your backcountry partners. Check slope angles, and to avoid avalanche terrain stay off of and out from under slopes steeper than 30° and adjacent slopes. Video Here
