Avalanche Advisory
Advisory: Moab Area Mountains Issued by Eric Trenbeath for Tuesday - February 23, 2016 - 7:26am
bottom line

There is a MODERATE avalanche danger in upper elevation, wind exposed terrain both for loose dry avalanches, as well as recently deposited wind slabs on the lee sides of ridge crests and terrain features.

At mid and lower elevations the avalanche danger is generally LOW.




special announcement

Hats off to Moab Powersports for stepping up and getting their snowbike riders educated about avalanches. These fellas just completed a 101 course with a nighttime classroom session and a day in the field. Good job guys!

current conditions

Wait, what is that? Fresh snow! The mountains picked up a surpise 6" last night starting around 8:00 p.m. This will certainly improve things, but you will need to seek out areas where the underlying snow surface is smooth for the best conditions. Lower angle slopes will also help cushion the blow on top of the old, hard, and sometimes featured surface.

Overnight winds have been in the 10-20 mph range from the northeast, but at 7:00 this morning they rose into the mid 20's with a gust to 33. Winter temps have returned and it's currently 8 degrees on Pre Laurel Peak and 15 at the Geyser Pass trailhead.

The new snow will easily slide off the variety of slick, hard surfaces out there so be alert to loose snow sluffs on steep slopes, primarily in upper elevation terrain. Mostly manageable, and not large enough to bury you, a loose snow slide could possibly sweep you off your feet and take you for a ride over a cliff or push you into a tree.

Winds were pretty well behaved during the storm but they have been on the increase since 7:00 a.m. Expect to find sensitive new wind drifts developing on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain. Mostly shallow and manageable, you can test for new wind slabs with a slope cut before dropping into terrain steeper than about 35 degrees.
