 Introduction:  Good morning, this is Max Forgensi with the USFS Manti-La Sal Avalanche Center with your avalanche and mountain weather advisory.  Today is Sunday, February 26th at 9:00 p.m.  This advisory will expire in 24 hours. 

 

WE HAVE 2 SPOTS LEFT IN OUR AIARE LEVEL 2 CLASS BEING HELD IN THE LA SALS THIS YEAR. THE CLASS WILL RUN FROM MARCH 3RD-6TH  (FRI-MON).  CALL (435) 636-3363 FOR MORE INFORMATION AND TO SIGN UP.  EACH CLASS IS LIMITED TO 12 STUDENTS.  TUITION GOES TO THE FRIENDS OF THE MANTI-LA SAL AVALANCHE CENTER.

MLAC NEWS: We have started an observer page for folks to send us their backcountry observations. Report what you see in your backcountry travels HERE. Please send us your reports on avalanches, ski conditions, road conditions, snow pit profiles etc. Thanks! You can also report observations at 435-636-3363

  

General Conditions:

        That pesky ridge of high pressure is starting to break down today and snow is on its way!  This much anticipated storm looks like it has a good chance of hitting us Tuesday and Wednesday…start washing your cars, burning skis, whatever to get some desperately needed precipitation to the La Sal Mountains.  Nordic and Skate skiing conditions will be fast today up to Geyser Pass.   Backcountry skiing conditions will be variable…sun crusts on South-West aspects, consolidated/rotten powder in wind sheltered North aspects below treeline and a variety of wind slabs above treeline.  The road to the Geyser Pass Trailhead is in great shape. 

 

 Mountain Weather: (At 10,500’)

Today: Partly cloudy, with a high around 45. South southwest wind between 10 and 15 mph, with gusts as high as 25 mph.
Tonight: Partly cloudy, with a low around 23. Breezy, with a southwest wind between 15 and 20 mph, with gusts as high as 30 mph.
Monday: Partly cloudy, with a high around 40. West southwest wind between 10 and 15 mph, with gusts as high as 30 mph.
Monday Night: A 30 percent chance of snow, mainly after 11pm. Mostly cloudy, with a low near 29. Breezy, with a southwest wind between 10 and 20 mph, with gusts as high as 30 mph.

Avalanche Conditions: (Link to the International Avalanche Danger Scale here)

 

The warming temperatures will definitely be stabilizing the lower elevations snowpack (hopefully not too much, we might not have any left).  Above treeline, the high temperatures are in the mid-twenties and we still have a shallow, winter, continental snowpack.  There are stiff wind slabs over extremely weak snowpack structures in some isolated areas above treeline. I feel it would still be possible to trigger an avalanche in localized areas above treeline as a result of last week’s wind event. This hazard will not be super widespread, and difficult to locate, just keep in mind that there are some booby traps out there on the high peaks. Steer clear of areas with a shallow rotten base and stiffer, cohesive, bridging slabs at the snow surface. Saturday’s BOTTOM LINE is an avalanche danger rating of MODERATE in these areas above treeline, meaning that human triggered avalanches remain a possibility. Never trust a rotten, faceted snowpack like we have here in the La Sals. If we don’t get some more snow, this situation will be with us into spring and we may never see a truly green light snowpack with low hazard.

 

We need your observations! Call 435-636-3363 or use the link near the top of the page to get to the observers page! Yes, DO IT!
