In sintesi

There is a MODERATE avalanche danger today where it will be possible for humans to trigger wind-drifted snow avalanches in steep (greater than 35°) mid and upper elevation terrain. Wet snow avalanches will be likely on east-south-west facing slopes and in low elevation northerly facing terrain. Today's wet snow problem is matter of timing, avoid steep slopes during daytime warming, as all of the recent storm snow will become damp and come down the mountain. Steep gully features facing south and west are prime places for humans to be involved with naturally-triggered wet snow avalanches. These wet snow avalanches could be long running, starting as dry snow and turning wet as they make their way downslope. Avoid traveling underneath avalanche paths, even on dry hiking trails this afternoon.

The danger will rise today and may reach CONSIDERABLE for wet snow avalanches, which are likely to occur on easterly, southerly, and westerly facing slopes and on low elevation north facing slopes. This problem can be managed with timing. Get off of steep slopes as the day warms up. Steep gully features and rocky terrain are likely places to see wet snow avalanches. The likelihood for wet snow avalanches will increase today, and you are likely to see natural wet snow avalanches on steep south and west facing terrain this afternoon.

Expect to see drifts of wind-blown snow on the downwind side of ridgelines and terrain features. The wind-drifted snow has created soft and sensitives cornices on the ridgelines and these cornices may break further back than you expect and trigger soft slab avalanches below them.

Mountain winds can be swirly and often load steep slopes at all aspects in the mid and upper elevation terrain band regardless of wind direction. Today, these wind drifts will be more stubborn and allow you to get further onto the slope before potentially breaking above you. This is a bigger concern in extreme no-fall terrain such as hanging snowfields and exposed gully features.

Recent Activity

Yesterday, there were no backcountry avalanches reported to the Utah Avalanche Center from the Provo Region. You can check out all recent observations and avalanches HERE.

Snow and Weather

Currently, under partly cloudy skies temperatures are in the high 20' to mid 30's °F. Winds are blowing from the west in the teens gusting to the 20's MPH. Storm totals range from 1"-3" of snow. The new snow that fell was mostly graupel and rimed precipitation particles and it made for a great refresh with the wind helping to fill in old tracks in the backcountry. Today, look for partly cloudy skies with increasing sun this afternoon. Temperatures will be in the low to mid 40's °F. Winds are forecast to blow from the northwest 10 gusting to 15 MPH at the 9,000' ridgelines and from the northwest 25 gusting to 35 MPH at the 11,000' ridgelines. Wind speeds should decrease through the morning.
