The avalanche danger is Low on all aspects and all elevations. As the day warms up, minor wet-loose avalanche activity can be expected. In your planning for today, provide an easy exit if you find yourself on a slope that is experiencing any wet avalanche activity.

Special Announcements
The UAC staff has published a blog with answers to the numerous questions we received but were not able to answer during the Q & A session for the online meeting regarding the Wilson Glades February, 6 accident.
Weather and Snow
Skies are clear and there is a temperature inversion, with low-elevation trailheads in the low 20's F, while the mid and upper elevations bask in the upper 20's F. Winds are light - less than 10 mph - although at 11,000' northwest winds are gusting into the low 20's mph. It sure felt like winter a week ago.
Many mountain locations picked up a trace to 1" of new snow early Thursday morning.
For today, expect continued Spring weather with clear skies and plenty of sunshine. Temperatures will rise well into the 30's and southerly winds will remain light. Warm and very breezy conditions Saturday with a weak, dry cold front Saturday afternoon. Warm temperatures will continue Sunday and Monday, with promising signs for a return to unsettled weather by perhaps Tuesday.

Our Week in Review - where we highlight significant avalanche and weather events from the past week - has been published.
Recent Avalanches
Minor wet-loose activity was noted on Thursday, but one party in the Y-Not Couloir - a steep, north-facing couloir in Little Cottonwood Canyon - experienced wet activity that funneled down through tight portions of the chute. This occurred mid-day and was possibly due to some greenhousing where the clouds trapped heat. Nikki also noticed north aspects getting damp yesterday on her field day in Mineral Fork.

Description
We have gone through our first wet avalanche cycle of the season this past week, and the snowpack has mostly adjusted to the warmth and sunshine. Although I am expecting additional wet-loose avalanche activity by late morning, it should follow the description of Low danger which states "small avalanches in isolated areas or extreme terrain." This terrain includes southerly aspects as well as northerly slopes that are exposed to the sun.
Evaluate snow and weather conditions as you travel and update your own forecast based on what you are observing.
Additional Information
What happened to the persistent weak layer near the ground? The layer still exists but it is mostly dormant, and we don't expect avalanches to happen on it until something changes in the weather. A major spring storm with feet of new snow could awaken this layer. It also may be a problem again on slopes that produced big avalanches following the series of storms that happened near Valentine's day in the middle of February.
