Forecast: Ogden Area Mountains - Utah Avalanche Center

Forecast for the Ogden Area Mountains

Issued by Dave Kelly on
Tuesday morning, January 21, 2025

With increased wind speeds and snow available for transport, there is a MODERATE avalanche danger for triggering a wind drifted snow avalanche in mid and upper elevation terrain. There is a LOW avalanche danger in low elevation terrain.

Strong winds can often load slopes on all aspects at mid and upper elevations, keep an eye out for pillowy, rounded areas of wind-drifted snow and avoid those slopes.

Weather and Snow

Under clear skies trailhead temperatures are right at 0 °F in many locations. Upper elevation weather stations are in the low single digits °F. Winds are blowing from an easterly direction in the teens gusting to the 20's at the lower ridgelines and from the west in the 20's gusting to the 40's at the higher ridgelines. There was no new snow overnight.

Today, look for mostly clear skies with temperatures rising to 22-28 °F. Winds will blow from the west at the higher ridgelines in the 30's gusting to the 40's and ramping up to the 60's MPH by later this afternoon. Winds at the lower ridgelines are forecast to blow from the west, however in some locations you may see winds coming directly out of the east. Read more about mountain winds HERE. There is no new snow expected today.

Even with extremely cold air temperatures some south and west facing aspects will have a slight melt freeze crust just below the surface that in most locations won't affect the sliding conditions, but is a unique occurrence, and worth noting if it still exists before our next storm. Drew also mentioned some near surface faceting in his observation from the Ben Lomond area.

Recent Avalanches

Yesterday, we had no reports of avalanches to the UAC from the Ogden Region. Read all observations HERE.

Description

Wind drifts will be easy to spot as they will be pillowy, rounded, and located on the windward side of ridgelines, gullies, and terrain features
Cornices on ridgelines are a sign that the slope below has been wind-loaded, and these cornices will be sensitive today
Cracking and collapsing in the snow are warning signs that the wind drifted snow is sensitive and would make an avalanche on slopes steeper than 30 °

Description

The cracking, collapsing, and whumpfing has subsided and the lack of in-your-face weakness makes for a tricky problem. Most likely areas to trigger an avalanche 1'-3' deep and up to 100' wide are thin rocky areas, gully features, and locations that have avalanched earlier this season and have reloaded with new storm and wind-drifted snow. Any slope that matches these characteristics and receives additional wind loading today will be suspect.
