Points saillants

There is MODERATE avalanche danger today, with human-triggered wind-drifted snow avalanches possible on steep slopes (35°+) at mid and upper elevations. Wet snow avalanches are likely on east-, south-, and west-facing slopes, as well as in low-elevation north-facing terrain.

Timing is key—avalanche danger increases as the sun heats the snow. Steep gullies on south- and west-facing aspects will be the most likely spots for naturally triggered wet snow avalanches, which could involve people. Avoid traveling underneath avalanche paths, even on dry hiking trails, this afternoon.

Start early, monitor for signs of warming, and exit solar slopes before they become unstable. Be prepared to adjust your tour plan based on your observations throughout the day. With such high temperatures and a poor overnight refreeze avalanche danger could even rise to CONSIDERABLE by the afternoon.

The March sun is strong. Regardless of air temperature or wind speed, expect wet loose avalanches, roof slides, and a gloppy snow surface on easterly, southerly, and westerly aspects, as well as low-elevation north-facing slopes.

Avalanche danger will rise through the day and may even reach CONSIDERABLE for wet snow avalanches by this afternoon. As the likelihood increases, natural wet snow avalanches will be possible on steep south- and west-facing terrain later in the day.

Timing is key—get off steep, sunlit slopes before they become unstable. These avalanches can impact more than just your group, so stay aware of others traveling above or below you. Even a small slide could entrain a lot of snow today.

Winds at the highest elevations have remained strong for days, still gusting near 80 MPH this morning. They’re expected to stay elevated through the morning before hopefully decreasing.

The winds continue building both soft and hard wind slabs, which will grow larger and more cohesive through the day. While most prominent on leeward south- to east-facing slopes, strong winds can load any aspect and drift snow farther downslope than expected. Check the avalanche heat map—recent slides highlight how unpredictable mountain winds can be, loading steep slopes across many aspects at mid and upper elevations.

Today, wind drifts will be more stubborn, allowing you to get farther onto a slope before they potentially break above you. This is a bigger concern in extreme, no-fall terrain like hanging snowfields and exposed gullies.

Use caution in steep terrain where drifting snow has accumulated. Watch for signs of instability like cracking, collapsing, fresh cornice growth, or pillowy features. If you see any of these, avoid traveling on or beneath wind-loaded slopes. Cornices are growing larger and are more likely to fail in high winds or warming temperatures—give them a wide berth.

Recent Activity

Yesterday, there were no new avalanches reported for the Provo area mounatins. Just to the north, in the Salt Lake area backcountry, several soft slabs and one hard slab were triggered, with a mix of rider involvement across various terrain features, along with both natural and human-triggered cornice falls.

Snow and Weather

This morning, skies are clear with temperatures ranging from the mid-30s to low-40s°F. Overnight lows did not dip below freezing in all locations. Winds are out of the west-northwest at 10-15 MPH, with gusts in the 20s and low 30s at lower ridgelines and 30 MPH, gusting into the 50s, at the highest peaks.

Today, skies will be partly sunny, with temperatures climbing into the mid 50s°F. The most notable change will be above-freezing temperatures potentially reaching the higher peaks and ridges, especially later in the afternoon. Northwest winds will continue at 5-10 MPH, gusting to 15 MPH on lower ridgelines, and 20-30 MPH with gusts up to 40 MPH at the highest elevations. Some of the highest ridgelines are already seeing gusts exceeding the forecast. This pattern played out throughout the day yesterday and could repeat again this morning. Expect strong gusts at the highest elevations. Winds should be strongest this morning, gradually decreasing through the day.

Looking ahead, significant warming is expected through at least Wednesday or Thursday, with cooling to follow.
