In sintesi

The avalanche danger is LOW and avalanche conditions are generally safe, with sluffing in the top few inches of storm snow likely on steeper aspects the primary avalanche concern.

Be prepared to adjust plans with any sudden changes in the weather, including wet-loose avalanches if the sun appears or if the storm snow becomes reactive during any period of high precipitation intensity.

Instabilities within the storm snow have settled out, leaving a dense and cohesive slab 12-18" deep that is well-bonded to the old snow surface, with the top few inches of loose graupel (Mark Staples photo from Grizzly Gulch).

These are great conditions for April powder skiing, and although avalanche conditions are generally safe, you can expect sluffing in the storm snow on steeper aspects. In addition, here are a few other things to watch for today:

- if the sun comes out for any period of time, wet-loose avalanches will be possible;

- if the winds blow stronger than forecast, you may find sensitive wind drifts;

- during any period of high precipitation intensity the storm snow may become reactive.

Be willing to adjust plans in response to any sudden changes in the weather.

Special Announcement

Sunday, April 18th will be the 163rd avalanche forecast and the last one for the 2020/2021 season. For the rest of the month of April, we will provide updates on the snow and weather anytime it snows which is hopefully a lot. We will also continue to post observations.

Recent Activity

No backcountry avalanches were reported from the Provo mountains on Thursday. Further north in the Salt Lake mountains, a 2' deep and 60' wide soft slab avalanche involving recent storm snow was intentionally triggered yesterday just above East Bowl Pass in Silver Fork (photo below). The only other reported avalanche activity was widespread sluffing in the top few inches of dense snow (with some graupel) on steeper slopes.

As always, find all of our observations and recent avalanches HERE.

Snow and Weather

Temperatures this morning range through the upper teens and winds are from the west/northwest and light, less than 10 mph, with gusts of 15 mph at 11,000'.

Another 1-2" of snow has fallen overnight, bringing snowfall totals since Wednesday of 12-18".

For today, expect cloudy skies with temperatures in the 20's and low 30's F. Winds will be from the west/northwest and should remain light, with gusts in the teens. On and off snow showers may deliver another 1-3" during the day.

Although specific to the Salt Lake mountains, our final Week in Review for the 2020/21 season - where we summarize significant weather and avalanche events for the prior week - has been published.
