Today's avalanche danger on the Manti Skyline is MODERATE.

In areas with recent deposits of wind drifted snow, human triggered avalanches are possible.

Avoid steep slopes that have fresh drifts, pillows, cornices and slabs of wind drifted snow.

The most likely spots to trigger something is on the north and east sides of the compass.

    Areas with deposits of wind drifted snow are the biggest threat out there today. Many of these are shallow and don't have serious consequences if you trigger one. Some will be deeper and on larger slopes that have serious consequences.

    Simply avoid steep slopes where the wind has been depositing snow. The most likely places to trigger something are on steep slopes that face northeast, east and southeast but watch for fresh pillows and drifts around terrain features on all aspects. INCREASED WIND SPEEDS THIS AFTERNOON WILL INCREASE THE AVALANCHE DANGER.

    Sorry folks, you're going to hear me talk about the old Persistent Weak Layers for some time to come still. During fieldwork on Monday while riding sleds through Seely and Becks Creek (east of Ephraim Canyon), my partner and I experienced collapsing and shooting cracks in a number of locations. The common theme was a shallow, sugary underlying snowpack (3 feet or less) with a recently formed wind drift on top of it. Any steep slope with this setup is suspect. The only thing you can do is avoid steep slopes where this situation is present.

Recent Activity

There's been widespread shallow wind slabs that have released naturally over the last several days. There have also been a few snowmobile triggered pockets. Most of these are around 8 inches deep but some pockets are breaking up to a couple of feet. Of note in the photo below, we collapsed and cracked out the slope to the left of the avalanche when we climbed it. It failed in weak faceted snow near the ground. It just wasn't steep enough to avalanche.

Snow and Weather

Current Conditions: Temperatures bottomed out below zero last night but have started rebounding already. Wind has remained moderate in speed from the west northwest for days. This has produced a moonscape of wind damaged surface snow in many locations.

Mountain Weather: We'll have clear skies and much warmer temperatures today. Highs should actually get into the 20s. Moderate speed west northwest wind is going to continue and it looks like it's going to get pretty strong this afternoon. Clear skies continue on Wednesday with slightly cooler temperatures.
