Points saillants

No major change in conditions is expected through the weekend.

The majority of the terrain on the Manti Skyline has a MODERATE avalanche danger rating today.

There is still a chance that a person could trigger an avalanche that breaks into weak sugary loose snow from earlier in the season.

The most likely places to trigger something is on very steep north through east facing slopes.

    Layers of weak sugary faceted snow that formed earlier this year are present throughout our snowpack in many areas. These weak layers have produced some avalanche activity after every significant storm (which have been few and far between). Your main concern this weekend is the chance of triggering an avalanche that breaks into this loose sugary snow. The likelyhood of triggering one is decreasing but if you trigger one it will probably be a couple feet deep and that's more than what I'd call a "manageable" situation.

    My co-worker Drew Hardesty hosts podcasts for the UAC. He and I had a conversation years ago that he decided to publish. It will give you insight to me as a forecaster but more importantly there is lots of information about Persistent Weak Layers, how they form, problems with them and how to deal with them. It is pertinent info for this season as we've had layers of loose sugar nagging at us all season and they continue to be a concern.

Special Announcement

I am pleased to announce that we have a new version of our Utah Avalanche Center app available. This is a huge improvement over our older version which I disliked and did not recommend to anyone. This version has an inclinometer for measuring slope angles. We plan to add new features on the next version this summer but this is a great start and again, a huge upgrade from our previous version.

Snow and Weather

Current Conditions: Wow, it was really warm on Saturday with many stations hitting 50˚F in the mountains. They dropped back into the mid 20s overnight for the most part. Wind has been light and variable in direction. Riding conditions are what you'd expect in April. Mornings have stiff frozen crusts then things soften as daytime temperatures warm and make the snow damp.

Mountain Weather: It'll be another very mild day in the mountains with high temperatures again into the 40s. We'll see mid and high level clouds start moving in from the south through today. I'm guessing the sun will filter through for the most part. Wind will be light mostly from the southeast. Sunday looks pretty similar with light wind from the southwest perhaps increasing in speed a bit later on. A storm system will move through Monday into Tuesday that looks like it could at least provide an ok refresher.
