Forecast for the Salt Lake Area Mountains

Issued by Nikki Champion on
Thursday morning, April 2, 2020
Most terrain has a generally LOW avalanche danger. However, areas of MODERATE danger exist at all upper elevations for triggering a fresh slab of wind drifted snow. These wind slabs will be generally shallow and isolated to terrain features that allow for drifting snow to accumulate.

Pay attention to changing springtime conditions and evaluate terrain carefully.

Weather and Snow
This morning, temperatures have dropped significantly since yesterday. Mountain temperatures are currently in the mid-teens F at trailheads and single digits at ridgelines. Winds are westerly averaging 5-10 mph at mid-elevations with gusts up to 20 mph. At 11,000 ft winds are averaging 25-35 mph with gusts near 50 mph. Last night into the early morning hours 2-4.5 inches of low-density snow fell across the area. (.15-.20 inches of water)
Today will continue to be mostly cloudy with an occasional snow shower. Temperatures will rise to the mid-20s F at trailheads and upper teens at ridgelines. Winds will continue to be westerly averaging 10-20 mph with gusts below 25 mph at most elevations. At 11,000 ft winds will average 20-30 mph with gusts up to 45 mph. The occasional snow shower could bring another 2 inches of low-density snow to the area before tonight.
A warming and drying trend will begin tomorrow into the weekend.
Note on Alta Guard precipitation from Mark Saurer at UDOT:
March totals are 48" of snow with 3.96" of water (March average is 87" of snow with 7.95" of water).
The year to date total is 391" of snow with 39.92" of water. (Average year to date totals through March is 416" of snow with 38.38" of water).
We need 91" of snow in April to bring us up to our average annual snowfall (Snow total average for April is 66").

Description
The last few days of strong winds in combination with a few inches of overnight snow will drift and form fresh slabs today. These winds drifts will be small and stubborn, as they will have had only a few inches of snow to move around the last few days, but with elevated winds, any new snow that is available for transportation will be transported.
Look for shallow slabs of wind drifted snow on isolated upper elevation terrain features that snow could be deposited, such as ridgelines and gullies. With multiple days of winds from all directions, these wind drifts can be found on all upper elevation aspects.
Look for any slopes with signs of wind drifted snow, and avoid those slopes. Wind affected snow often looks wavy, rounded, pillowy, and can sound hollow when walking or riding on it.

Pay attention to cornices: Many ridgelines now have overhanging cornices, and Tuesday there were a few reports of cornice triggered wind slabs. A few days of strong winds at the uppermost ridgelines have made cornices even larger. Be sure to give cornices a wide berth as they typically break much further back than expected.
