Points saillants

Today, MODERATE avalanche danger exists at upper elevations on all aspects, with human-triggered avalanches possible in wind-drifted or lingering new snow on steep terrain. Danger decreases with elevation and wind exposure, but small avalanches may still be found in isolated areas or extreme terrain at mid and lower elevations.

Carefully assess snow and terrain, as additional snowfall, increased winds, or even brief sunshine could quickly increase instability.

Use safe travel techniques—only one person on steep terrain at a time.

With plenty of new snow available for transport and easterly winds—a direction that is notoriously undercaptured in the Wasatch and can load terrain in unique and challenging ways—soft wind drifts have formed at upper elevations and potentially even mid-elevations, where human-triggered avalanches will be possible. Watch for and avoid pillowy wind features and steep slopes showing signs of wind loading, such as cracking in the new snow.

These drifts will form on the downwind side of ridges and gullies, so stay back from sensitive new cornices along ridgelines. A cornice collapse could trigger a new or wind-drifted snow avalanche.

The new snow stabilized quickly throughout the day yesterday. However, storm totals remain high, and temperatures are still low this morning. As a result, sluffing or soft slab avalanches involving the new snow remain possible on steep slopes outside wind-affected terrain.

Now that it's April, even brief sunshine can rapidly heat the snow, turning dry loose avalanches into wet loose slides. Lower-elevation and south-facing slopes, along with mountain roofs, will be most affected. Signs like rollerballs, dripping water, or sinking into soft snow indicate it's time to move to higher, colder terrain.

Recent Activity

In the Provo area, there was one skier-triggered 12" soft slab avalanche occurred at 9,800' on a northeast aspect in Caribou Canyon, Provo. The avalanche was caused by a touchy storm slab, with wind-loading contributing to the instability. This failed on a density change within the new snow.

Nearby, ski patrols found storm instabilities settled out for the most part but remained reactive to control work early in the day. Most areas saw little reactivity to ski cuts compared to Wednesday, and by the end of the day, lingering instabilities had mostly stabilized.

Snow and Weather

Currently, skies are mostly cloudy, with light snowfall in the mountains and an additional trace of new snow since yesterday evening. Trailhead temperatures are in the upper 20s °F, while the highest peaks sit in the upper teens °F. Winds at mid-elevation ridgelines have shifted northeasterly, blowing in the single digits and gusting into the upper teens. At the highest ridgelines, gusts are reaching near 20 MPH, with overnight gusts peaking near 30 MPH. Easterly winds are generally not well captured across the Wasatch.

Today, skies will remain mostly cloudy, with occasional snow showers in the afternoon. Temperatures will rise into the mid-30s °F. Winds will be from the northeast at 10–15 MPH, gusting to 20 MPH. Expect trace amounts of new snow by 5 PM.
