General Conditions:

Conditions remain unchanged in the La Sals with a mixture of sun crusts, wind slabs and sastrugi above treeline. Conditions below treeline aren’t much better as the rotten base makes for very tricky conditions in the powder for skiing, boarding or snowmobiling out there. The trace of snow that fell Sunday afternoon won’t be enough to freshen up the mess that is our snowpack here in the La Sals.  The best ride out there is still on the packed out roads and trails of the La Sals. The cross-country and skate skiing are excellent.  We still need a good solid snowfall to cover most of the obstacles still present in the backcountry.  The NWS has upped the precipitation forecast for Wednesday night to 2-4 inches so hope for the best!  This one is supposed to be measured in feet (not inches) in the Northern part of the state so pray we at least get some of it!

The road to the Geyser Pass Trailhead has been plowed, but it is really slick in places, 4WD and chains are still recommended, especially for the ride down.  

Current Conditions: (click location for latest data)

Geyser Pass Trailhead (9,600’):  10.5” at the SNOTEL.  17” at the GPTH Snowstake, 15 degrees at the Geyser Pass trailhead at 7:00 a.m.  19 degrees in Moab.

Gold Basin and South Mountain:  At least 24” of settled snow on the ground.

Pre-Laurel Peak Weather Station (11,705’):  First information of the year!  Winds are light, out of the northwest at 5-10 mph.  Temperature at 11,600’ is 18 degrees.  We’re not online with the information yet but stay tuned.

Mountain Weather: (At 10,500’)

Today: Mostly sunny, with a high around 40. South southwest wind between 5 and 10 mph, with gusts as high as 20 mph.
tonight: Partly cloudy, with a low around 21. South southwest wind between 5 and 10 mph, with gusts as high as 20 mph.
Wednesday: Mostly cloudy, with a high near 31. South southwest wind between 10 and 15 mph, with gusts as high as 30 mph.
Wednesday Night: Snow likely. Cloudy, with a low near 16. Breezy, with a southwest wind between 15 and 20 mph, with gusts as high as 30 mph. Chance of precipitation is 70%. New snow accumulation of 2 to 4 inches possible. Yeah.

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

            Not much going on in avalanche land out there, YET. We still have some very weak snowpack structures and wind slabs up high so we are keeping the avalanche danger at MODERATE on upper and mid-elevation (at or just below treeline)  E-NE-NW facing slopes steeper than 35 degrees. We are calling the avalanche danger LOW elsewhere in the range. This means that the possibility of human triggered avalanches does exist, so use careful route finding if you’re out bagging peaks in the La Sals. Stay on the ridges and avoid downwind, loaded slopes. The variable to watch now is this next storm. The snow that has been on the ground in the La Sals is very thin and rotten. Even a small load of new snow is likely to result in instability and possibly some large avalanches. Here’s an example: 10 days ago we measured 5” of new snow at the Geyser Pass Trailhead. This equated to 10” in Gold Basin at 9600 Ft. Winds came up the following day from the south and 36 hours after the end of the storm a monster avalanche up to 5ft. deep and ¾ of a mile wide released in Upper Horse Creek on the backside of Pre-Laurel Peak. This is a pretty typical scenario in the La Sals, so remember; when we get the new snow (we hope!) the Avalanche danger will be on the rise.

 

We would like to invite everyone to attend a Basic Avalanche Awareness Seminar on Friday the 13th at the Moab Information Center at 7:00 PM. Free Admission.
