Moab Avalanche Advisory

Forecaster: Dave Medara

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.
(click HERE for tomorrow's danger rating)


Danger Rose Tutorial

Moderate Hazard of Avalanches in the La Sal Mountains at this time. Hazard primarily limited to above treeline slopes due to limited snow cover. Wind slabs on all aspects in shallow pockets and gullies due to variable high speed winds.

Excellent conditions for Rock Climbing, Biking and other non-snow related activities continue in SE Utah. Conditions not so favorable for skiing at the moment. Snow outlook is for a good storm this weekend.


CURRENT CONDITIONS

Good Morning this is Dave Medara with the La Sal Avalanche Center. It's Friday December 12th at 11 AM. Not much to report since the last advisory, winds have been behaving, snow has been settling, melting and re-crystallizing in the La Sals. Hope you got out  to play this week and hopefully it wasn't in the La Sal Backcountry. If you venture off the roads and trails, the ski conditions are extremely poor at the moment. The good news is, if the forecasts prove to be correct, that we have a significant amount of snow on the way. More details on that in the weather section. 

We Picked up 5" of new snow last Monday and have a total of 17.5" in Gold Basin. This puts us at about 64% of normal snowpack for the season.   Our snowpack is shallow and rotten, as usual for this time of year.

San Juan County was up on Thursday to clear the roads and they are in great shape right now. 

The Grooming program starts tomorrow so time to wax the skis.


RECENT ACTIVITY

Class 1 activity in Tukno Ne slide path and in Talking Mountain Cirque noted on Tuesday's tour.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 72 hours.

Moderate avalanche danger. Shallow pockets on all aspects above treeline. Lots of cracking and collapsing out there Tuesday on south and NE aspects that I toured to. The long high pressure grew some weak faceted crystals out there that are now covered by small wind slabs on most above treeline aspects due to variable wind direction and high wind speeds. The joke will be on you if you get caught out there right now because the skiing/riding is definitely not worth it! Lack of snow coverage limits the danger to the high alpine slopes above treeline. Expect the Avalanche Danger to rise significantly if this next storm delivers. We have a typically weak underlying snowpack structure here in the La Sals, and it will not take much snow and wind to create unstable snowpack conditions.

GENERAL ANNOUNCEMENTS

The Grooming Program will start on Saturday the 13th (conditions permitting) and The Lower Utah Nordic Alliance (LUNA) is looking for volunteers to help with grooming this winter. Contact Kiersten at 260-0042 if you're interested.

Our yearly AIARE level I avalanche course will be held this year from Friday, January 30th - Sunday February 1st. Proceeds from this class go directly to the Friends of La Sal Avalanche Center and help pay for the forecasting and education services provided by the Center. Please call Dave or Max 435-636-3363 to sign up for the class or get more information.

We will also be teaching some Avalanche Awareness seminars  this winter. The first is scheduled for Monday, January 12th at 6:00 PM. These FREE seminars run about 2 hours and cover avalanche phenomena, basic travel techniques and self-rescue equipment overviews. They are a good opportunity to learn about the hazards of winter travel that winter recreationists face when traveling in the backcountry. Suitable for skiers, hikers, snow machiners, hunters and snowboarders.
