Forecast for the Provo Area Mountains

Dave Kelly
Issued by Dave Kelly for
Monday, January 30, 2023
The avalanche danger is CONSIDERABLE on upper elevations for wind-drifted surface snow. The avalanche danger is MODERATE for new snow avalanches running on a crust/facet combination buried 2-3' below the surface at mid and upper elevations. The avalanche danger is LOW in lower elevation terrain. Expect to see dry loose avalanches in steep terrain and on any solar warmed slopes.

Cold temperatures may keep natural activity at bay today, however human triggered avalanches are still likely in upper elevation terrain. There is world-class riding to be had on lower angle slopes and I will be assessing the new/old snow interface anywhere there is a crust present before traveling onto terrain approaching 35 degrees.

Weather and Snow
Under partly cloudy skies temperatures are in the single digits F. Winds are blowing lightly from the west at the 8000' ridgelines. Last night 1-2" of low-density snow fell. Today, winds will blow from the northwest 15 MPH gusting to 20 MPH at the 9,000' ridgelines and 20 gusting to 30 MPH at the 11,000' ridgelines. Skies will be partly cloudy with temperatures 14-18 F.
Recent Avalanches
There were a few reports over the weekend of avalanches 100-450' wide that ran on the interface between the new snow and the faceted crust. This crust/facet combination is most pronounced on west and southeast aspects. I would be digging down 2-3' deep to determine if this crust was present and how it was reacting to extended column tests before getting onto slopes approaching 35 degrees.

As of this morning we have had 27 avalanche reports from the Ogden, Salt Lake, and Provo regions from Saturday and Sunday with more slowly trickling in. There are some great observations and we appreciate everyone that takes the time to share what they see. Check out all observations HERE.

Description
Although wind speeds have dropped this morning there is still low-density new snow available for transport. Watch for cracking in the surface snow and avoid smooth rounded pillowy features below ridge tops and on the leeward side of gullies. Any slopes with large overhanging cornices will be a sign that the slope below has seen recent wind loading and has the potential to avalanche with the additional weight of an ascending or descending rider.

Description
Over the last few days there were a few new snow slab avalanches that got my attention all failing on the old/new interface where there was a crust present. There is a great report HERE from an AIARE Pro 2 class about how they assessed this crust facet combination.
