Points saillants

The danger will rise to MODERATE for wet avalanches on steep east to south to west facing slopes today. Both natural and human triggered slides are likely. Areas of MODERATE danger exist primarily in the upper elevations for lingering wind slab and new snow instabilities. Caution should be observed in steep terrain.

Despite cool morning temperatures, the storm snow will heat up in a hurry with direct sun and temps warming to the mid 40s at the mid-elevations, the mid-30s up high. 3-5" of cold snow will become damp and then wet and unstable, running fast and far on last week's suncrusts. Natural and human triggered avalanches will be likely during the heat of the day. Both wet sluffs and wet slabs are possible. When the snow starts becoming damp, move to a cooler slope or lower angle terrain.

Shallow new snow and pockets of wind slab may be found primarily in the upper elevations. These may be up to a foot in heavily wind drifted terrain. I don't expect the Provo mountains to be as active as the Salt Lake mountains today, but caution should be exercised in steep terrain with safe travel protocols required. Assess each slope carefully and identify features of concern.

Special Announcement

The Avalanche Research Program at Simon Fraser University is conducting an online survey to examine how people use avalanche safety information. They want to hear from all backcountry users to understand how they process information provided in public avalanche forecasts. Anyone who completes the survey before May 15th will be entered to win cash prizes.

Recent Activity

Yesterday, there were no new reports of avalanches in the Provo area. In the Central Wasatch, there were over 30 reported human triggered slides 10-16" deep and up to 200' wide. Most were running on last week's thermal crust or within the new snow. Collapsing and cracking was noted in some steep terrain there.

Snow and Weather

Skies are clear with light northwest winds and temps in the upper teens to low 20s. Yesterday perhaps a trace fell but 48 hour snow totals are 3-5 inches of snow (.1-.34 inches of water). For today, we'll have sunny skies, light winds backing to the southwest and temps rising to the mid-40s at the mid-elevations.
