Kernpunkte

The avalanche danger is MODERATE on all slopes facing northwest through north and east, and mid and upper elevation slopes facing west and southeast. All other slopes have a LOW avalanche danger. MODERATE danger with a buried persistent weak layer is not a green light nor is it the same as MODERATE danger with another type of avalanche problem. Evaluate snow and terrain carefully to identify thin, rocky, steep areas where slab avalanches may fail in a persistent weak layer buried 2-5' deep.

With today's warming you may see wet avalanche activity on lower or mid elevation slopes out of the wind zone.

These avalanches involving buried persistent weak layers are not to be fooled with; if it's a thin snowpack over steep rocky terrain then you're taking a gamble. While the danger may have dropped from Considerable to Moderate the mountains don't care what the avalanche forecast is. For today, I will still be assessing terrain and avoiding zones that are steep and rocky with dry facets now buried close to the ground as these are the areas where you are more likely to trigger an avalanche.

If you choose to venture into steeper terrain:

Continually evaluate the snowpack looking for thinner areas where it may be easier to trigger an avalanche in the buried PWL

Avoid steep, rocky slopes where the snowpack is likely to be thinner

Back off of steep slopes when red flags are present, such as collapsing or recent avalanches

Recent Activity

There were no reports to the UAC from the Ogden area yesterday. If you're out and about submit an observation HERE. There was an avalanche reported from Ant Knolls on the northern edge of the Provo Forecast region. This avalanche is representative of what you may find during Moderate danger with a buried persistent weak layer in the Ogden Area mountains.

Snow and Weather

This morning, under partly cloudy skies trailhead temperatures are in the 20's° F while the highest ridgelines are in the high-teens to low 20's °F. Winds are blowing from southwest in the low-teens gusting to the 20's MPH at the 8,000' ridgelines and in the mid 20's gusting to the high 20's MPH from the northwest at the 9,000' ridgelines. There was no new snow overnight. For today, we should see mostly sunny skies with temperatures from 34-37°F and winds blowing from the north-northwest 10 gusting to 15MPH at the 8,000' ridgelines and 25 gusting to 30 MPH at the 9,000' ridgelines. Winds are forecast to decrease throughout the day.

Looking forward we can expect to see progressively warmer temperatures with clear skies through the middle of the week with the next storm on the horizon for the end of the week. Read more from our partners at the National Weather Service HERE.
