Forecast for the Provo Area Mountains

Issued by Nikki Champion on
Tuesday morning, March 25, 2025

The avalanche danger will rise to CONSIDERABLE on all west, south, and east facing aspects and low elevation north facing aspects where we will see wet snow avalanches with daytime warming. This wet snow problem is a matter of timing, with the danger of these avalanches rising throughout the day. Steep gullies on south and west aspects will be the most likely spots for naturally triggered wet snow avalanches involving people. Avoid traveling underneath avalanche paths, even on dry hiking trails, this afternoon.

The remaining aspects and elevations will have a MODERATE avalanche danger today, with stubborn human-triggered wind-drifted snow avalanches possible on steep slopes.

Start early, monitor for signs of warming, and exit solar slopes before they become unstable. Be ready to adjust your tour plan based on your observations today.

Weather and Snow

This morning, skies are clear, with temperatures ranging from the mid-30s to low 40s °F and a slight temperature inversion in some areas. There was not a solid refreeze. Winds are out of the northwest at 5-10 MPH, with gusts reaching the 20s at lower ridgelines and 15-20 MPH, gusting into the 30s, at the highest peaks.

Today, expect mostly sunny skies and warming temperatures, reaching the mid-50s to even 60 °F in the mountains. Northwest winds will continue at 5-10 MPH, gusting to 20 MPH on lower ridgelines, and 5-15 MPH with gusts up to 25 MPH at the highest elevations. Winds should be strongest this morning, gradually decreasing through the day before shifting southeast by the afternoon.

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

Recent Avalanches

No new avalanches were reported in the Provo area backcountry. Ski patrol reported wet-loose activity by the afternoon.

Description

The March sun is strong, and we’re entering a period of poor overnight refreezes. 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 and mid-elevation north-facing slopes.

With several days of poor refreeze ahead, the risk of larger wet slab avalanches is increasing. In the Provo area, slopes that still hold faceted snow, particularly those facing west and east, will be especially prone to instability. While it may not happen today, it should remain on our radar. These avalanches occur when meltwater percolates through a layered snowpack for the first time, particularly after multiple days of strong melting and no overnight refreeze. There are several layers within the snowpack where water could pool, making this a concern both today and in the coming days, though there is uncertainty around how quickly or severely this might develop.

New/Old interface 1-2' down (see artificial pooling in the photo below): This is the first layer likely to see pooling and is the most suspect for shallow wet slab avalanches by this afternoon.

Early March dust/crust/facet layer & Repeater or thinner areas: These layers will take longer to saturate, but they remain a concern as water moves through the snowpack, potentially leading to large, destructive wet snow avalanches.

Bottom line for wet avalanches:

Get out early and get home early. Avoid slopes above 35 degrees when the snow becomes wet and unable to support your weight. Warning signs include rollerballs, wet sluffs, small sluffs growing into larger slides, and cornices breaking. If you notice any of these, change aspects or head home. Even smaller slides can be dangerous in high-consequence terrain, so always plan a safe exit route.

Description

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

Use caution in steep terrain with drifted snow. 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 more likely to fail in high winds or warm temps—give them a wide berth.
