Forecaster: Max Forgensi

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The bottom line for Tuesday will be an avalanche danger of moderate on steep slopes greater than 35 degrees in the La Sal and Abajo mountain ranges. Be careful around trigger points such as convex rollovers, trim lines and exposed rocks.

This advisory will be updated Friday morning.


CURRENT CONDITIONS

Reports of good skiing conditions are filtering in from the mountains. Sheltered below tree-line skiing seems to be the best bet, while upper elevation sunny aspects are challenging to navigate due to snow conditions.

LUNA volunteers went up on Monday and groomed the Meadow and Gold Basin tracks and up to Geyser Pass. Expect the upper Loppet loops to be marked and groomed by Friday afternoon. Thanks Kristi and Jesse!

High temperatures at the Geyser Pass trail head reached 37 degrees yesterday, while Camp Jackson hovered at 39 for close to 5 hours. Sunny aspects will be sun crusted today.


RECENT ACTIVITY

There is nothing new to report. Natural avalanche activity from the last storm was limited to NE-N aspects at and below tree-line.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

As we move farther away from the last storm, formerly sensitive cross-loaded and top-loaded wind slabs and new snow soft slabs shuffle into the persistent slab category. Our laccolith mountains of southeast Utah are built with moderate slopes up high, only to roll over a convexity half way or two-thirds of the way down a slope. These locations will be the most dangerous for a back country traveler. Mitigating the human factor in avalanche terrain will be the most difficult challenge. Risk vs. Reward. The level of commitment to a slope. Have numerous alternative objectives on tours and remember, you can always back off. Tomorrow is another day!


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

With high clouds burning off, the sun and temperature will affect sunny slopes today. Expect loose snow avalanches on steep slopes with good alignment to the sun.
