Highlights

The avalanche danger on the Manti Skyline remains MODERATE today. Human-triggered avalanches are possible on the north half of the compass above about 8500 feet in elevation. Watch for cracking within the new snow as well as collapsing or "whoomping" which indicates you are in an area with unstable snow.

    Snow that became very weak during January has formed a Persistent Weak Layer that is now our main avalanche problem. After a couple of days of fieldwork, I bumped the likelihood of triggering an avalanche by one notch. I've found that the collapsing and cracking are more widespread than I originally thought, given such a small amount of new snow that was added on Wednesday night. I would not be surprised to hear about human-triggered avalanches today. However, in general, they will be fairly small and not all that dangerous. If you are concerned about triggering something, the answer is always to stick to slopes less steep than 30°.

Recent Activity

There was one small avalanche reported from Ephraim Canyon on a small but steep north-facing slope. It most likely released naturally at the tail end of the storm.

Snow and Weather

General Conditions: Total snow depths are still only in the two to three foot range. Upper elevation terrain is holding decent, soft new snow. Riding conditions are a mixed bag but are still better than before the storm. I found quite good ski conditions in the 10,000' range on Friday. Chris Magerl was lower in elevation and found unsatisfactory conditions. DETAILS HERE. I also spoke with Cole Nielson who didn't think much of the snowmobile riding around Ephraim Canyon.

Temperatures dipped into the teens overnight and the wind remains light from the southwest.

Mountain Weather: Temperatures rebound today and we have a few warm days ahead. Today will have the most sun then more clouds Sunday and Monday. We'll have high temperatures into the low 30s. Wind will be generally light from the west today with increasing speeds on Sunday and especially Monday. It is still looking like we should pick up a decent amount of snow during the week next week.
