Avalanche danger
- Alpine
- Treeline
- Below treeline
Highlights
The avalanche danger is LOW and normal caution is advised. Watch for and avoid (1) shallow wind drifts in upper elevation protected terrain, and (2) fast running loose-snow avalanches in steep northerly terrain as the surface snow becomes weak and cohesionless.
REMEMBER that getting caught in even a small avalanche could have significant consequences with the risk of hitting a rock, stump, or downed timber.

Recent Activity
No new avalanches in the Provo area mountains.
In the Salt Lake area mountains, we have begun to see some small loose-dry avalanches in the weak faceted snow.
Pro observer Mark White saw some small fast-running dry sluffs in No-name Bowl yesterday.

Snow and Weather
This morning, under clear skies there is an inversion in the mountains with trailhead temperatures in the mid-teens F and mountain temperatures in the upper-20s F. Winds are currently South Southwesterly and blowing 5-10 mph at mid-elevations, with gusts near 20 mph at the upper elevations.
Snow depths are generally 6-12" and there's not enough snow to slide around on in the Provo area mountains.
For today, we will have cloudy skies in the morning with south-westerly winds and mountain temperatures in the upper-30s F until a fast-moving trough moves through the area this afternoon. This trough will bring cold temperatures and increased ridgetop winds, with gusts up to 25 mph. We could get a trace amount of snow overnight into the morning.
Additional Info
Looking Ahead: Although our current snowpack is thin, there is widespread variability. Strong winds in the middle of November scoured many slopes, while others got a firm wind slab compressed into the terrain. Since that time, we have had several cold and clear nights that promote a "faceting" process which weakens the snowpack, turning the snow crystals into sharp, angular, weak grains. With high pressure forecast for at least the next week, this faceting process will continue.
In the short term, the surface snow has become so weak, sluffing (loose-snow avalanches) has begun occurring on the steepest slopes.
In the long term, this weakening snow will become an issue once we get a load of storm or wind-driven snow on top of this weak snowpack structure. A perfect recipe for avalanche conditions.
Forecaster Greg Gagne gives a summary of what the snow looks like under his feet in upper Big Cottonwood on Thursday.
Weather Outlook: The longer-range models do not look particularly good for storms through mid-December.
