We need your help. In an effort to increase awareness and prevent future fatalities we need to reach more people with our daily avalanche forecasts, expand the Know Before You Go program, and increase the number of on-snow avalanche courses. Please consider a donation to the UAC to help us raise $25,000 by April 8.

Skies are mostly clear but for some high cloud cover overhead. In the black of night, one could make out the moon-dog with these high streamers moving through. The south to southwesterlies picked up overnight and are blowing 15-20mph with gusts to 35. The most exposed ridgelines have hourly averages of 25-30mph with gusts to 35. As of 4am, temperatures are already in the low to mid-30s. Snow surfaces will soften and become unstable much earlier with this fair-at-best refreeze. Upper elevation northerlies held the last vestiges of good riding, but they'll now have suffered a bit of wind damage.
With the ridge axis now just to the east, we'll see high thin clouds, moderate southwest winds, and scorching temperatures in the mountains. Many trailheads and base areas are forecast to reach near 60°F with ridgelines heading toward 40°F. Scorching temperatures will persist through Wednesday night when a disorganized system ushers in cooler temps and perhaps a few inches of snow.
Wet activity stayed mostly in check yesterday but for some relatively minor wet sluffs in steep sunbaked terrain. Dry sluffing, however, occurred with provocation along the steep upper elevations, but these too were mostly harmless.
Three, perhaps four skier triggered storm slabs released in the following areas: t
he Snowbird periphery to the south (upper AF); in the high alpine of
Mill B South, and in the
Bountiful/Sessions mountains. These were roughly
8-16" deep and up to 100' wide on steep north to east facing terrain between 9000' and 10,700'. (Nat Grainger photo below from Mill B South). One party experienced collapsing while approaching the Heart of Darkness couloir in upper Mill B South...and altered their plans. Never a bad decision.
