Moab Avalanche Advisory

Forecaster: Dave Medara

SPECIAL ANNOUNCEMENT

The Avalanche Danger Scale is being revised for next winter. Our friends up in Canada have created a short survey found at the following link. Please help ensure the new Avalanche Danger Scale is effective by completing a survey. http://surveys.globalepanel.com/wix/p319164581.aspx


BOTTOM LINE

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

Danger Rose Tutorial

Powder Skiing and Riding conditions are still good in many areas of the SE Utah mountains. Mid-elevation E-NE-NW facing slopes are reportedly good skiing at the moment. Avoid wind loaded areas, particlarly above treeline. Avalanche Danger rating MODERATE, meaning the possibility of human triggered avalanches still exists in isolated areas.


CURRENT CONDITIONS

Things are calming down a bit in the La Sals. Spring weather, although cool, has provided abundant sunshine to the Peaks of SE Utah and the strong sun this time of year has heated up and crusted over the sunny side slopes on SE-SW-W facing slopes. This will reduce the Avalanche Danger on these aspects and put a damper on any good skiing and riding conditions until we get a couple of more days of melt-freeze cycles. Good conditions can be found on shady side slopes, E-NE-NW facing, especially at mid elevations below treeline. We continue to hover around 100% of normal snowpack in the La Sals and about 90% in the Abajos. Clouds are just starting to move over the Moab Valley and the La Sals this morning and more snow may be on the way but it doesn't sound like a big storm.

The road to the Geyser Pass trailhead and the Dark Canyon trailhead has been plowed.

There has not yet been any grooming done since the new snow.


RECENT ACTIVITY

Snowpack has been well behaved since last Sunday.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Link to the U.S. Avalanche danger scale here: utahavalanchecenter.org/education/dangerscale

Solar radiation from the last two days of sunshine has dropped the Avalanche Danger to Low on SE-SW-W facing slopes where they remain crusted over. Expect to find a MODERATE Avalanche Danger on the shady side slopes E-NE-NW facing, where better conditions for skiing and riding will be found. Things have been relatively calm avalanche wise since this last storm, but we have had 2 feet of snow since last Friday and copious winds earlier this weak that have scoured some slopes, and loaded others. Approach wind loaded slopes with extreme caution. Remember to ski or high mark one at a time and stay clear avalanche paths and runout zones after your run.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 8 hours.

Watch daytime heating today with forecast warm temperatures. If the slope you are on is getting wet and mushy, and crusts that were frozen earlier in the day have melted off, then it is time to get out of there.
