Forecast for the Provo Area Mountains

Drew Hardesty
Issued by Drew Hardesty on
Saturday morning, December 18, 2021
Areas of CONSIDERABLE avalanche danger exist on northwest through easterly facing slopes above about 8500'. Avalanches may break down 2' deep and propagate over a hundred feet wide. It may also be possible to trigger them from a distance or from below. Pockety wind drifts may be found in the upper elevation bands and are to be avoided.

Weather and Snow
Skies are clear. Winds are generally light from the west. Mountain temperatures are in the teens.
For today, we'll have clear skies, light westerly wind and temps rising to the upper 20s.
Riding conditions are thin but fair in the Provo mountains. A recent storm dropped about a foot of new snow this past week.
The next series of storms are forecast to barrel through mid/late week. Stay tuned.
Recent Avalanches
We didn't hear of any avalanches reported from the Provo mountains, but the Salt Lake mountains remain very dangerous. An additional seven human triggered avalanches occurred yesterday 2-3' deep and hundreds of feet wide.

Description
A conditionally unstable snowpack exists on steep northwest to east facing slopes above about 8500'. This unstable layering has produced numerous dangerous avalanches in the SL mountains. It'll be important to dig down to look for this unstable layering and avoid steep terrain that harbors this structure. Look for a strong slab layer over a few inches of weak, sugary snow. Cracking and collapsing may or may not exist. At this point, I would avoid steep terrain on the north side of the compass as avalanches may be 1-3' deep and a hundred feet wide or more.
