Forecast: Provo Area Mountains - Utah Avalanche Center

Forecast for the Provo Area Mountains

Issued by Drew Hardesty on
Thursday morning, January 23, 2025

Pockets of MODERATE avalanche danger exist around the compass at the mid and upper elevations. It's still possible to trigger a stiff and stubborn hard slab of wind drifted snow 1-2 foot deep and perhaps 100 feet wide. On northwest to north to east facing aspects at the mid and upper elevations, there is still an off-chance of triggering a hard slab that steps into an old persistent weak layer buried 2-4' deep. Caution is still advised.

Special Announcements

Urgent battery replacement required for anyone who received batteries from one of our participating "Batteries for Beacons" shops. Please review the "Batteries for Beacons" replacement notice on our blog. Batteries distributed through our "Batteries for Beacons" program this year have shown to be inadequate length.

Join the UAC at Deer Valley on January 30th for the 2nd Annual Blizzard Ball Gala. Former Director of the Utah Avalanche Center, Bruce Tremper will deliver the keynote address.

Weather and Snow

Skies are clear.

Temperatures straddle 0°F. Winds are 10-15mph from the north and nearly double that along the 11,000' level.

For today, we'll have sunny skies, light to moderate winds from the northwest and temps slowly warming into the upper teens.

They say that there are hundreds of words that describe snow, but after the recent bout of strong winds, I'd say that there are only a few left suitable for polite audiences.

The Outlook: A storm out of the northwest splits, with a cut-off Low pressure system retrograding back to the southwest. Beyond that, who among us can forecast a wobbly cut-off Low?

If forced to guess, I'd say we might pick up a couple measly inches of new snow over the weekend with perhaps the Park City mountains and the Wasatch back receiving the lion's share.

Recent Avalanches

Trent Meisenheimer toured along the north side of Timp yesterday and found very touchy conditions with sensitive wind slabs 6-12 inches deep and cracks shooting out 150' wide. His excellent report can be found HERE.

Description

The backcountry is now littered with stiff and stubborn hard slabs of wind drifted snow. They'll be found all around the compass, but more commonly on aspects with an easterly component. They'll be found well off the ridgeline and eddied around unusual features. Remember, with hard slabs, you're "on top" of the pillow. With soft slabs, you're "in" the pillow. Hard slabs have a nasty habit of fracturing well after you're on to the slope. It may be another day or so before these rounded whales settle out and stabilize.

Description

The buried facets near the ground have been present since early season, with most avalanche activity on this layer starting around Christmas. The last known avalanche on this layer was skier-triggered in Upper Big Cottonwood on Thursday, January 16.

The cracking, collapsing, and whumpfing have subsided, and the lack of in-your-face weakness makes for a tricky problem. Many old-timers are still avoiding steep thin rocky terrain.

Most likely areas to trigger an avalanche 2'-4' deep and up to 100' wide: west to north to east facing terrain at the mid and upper elevations. Other considerations below:

Thin, rocky zones, gullies, and slopes that have previously avalanched and reloaded with storm or wind-drifted snow.
Any large cornice fall may be enough to trigger one of these avalanches.
A new wind slab avalanche may step down into the older PWL.
