Uintas Avalanche Advisory

Forecaster: Craig Gordon

SPECIAL ANNOUNCEMENT

We now have three western Uinta specific weather stations up and running.

For Weber Canyon and upper Chalk Creek- Windy Peak (wind and temperature) and Giant Steps (snow depth and temperature)

For the region around Mirror Lake- Lofty Lake Peak (wind and temperature)


BOTTOM LINE

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

Danger Rose Tutorial

At and above treeline the avalanche danger is MODERATE today and human triggered avalanches are possible on wind drifted slopes steeper than about 35 degrees, especially those facing east, north, and northeast.

In wind sheltered terrain the avalanche danger is generally LOW.


CURRENT CONDITIONS

The trailing edge of a storm system brushing the northern half of the state brought clouds and strong southwest winds overnight. Along the high ridges winds are blowing 25-40 mph with a few gusts in the 50’s. Currently, temperatures are in the mid 20’s at 8,000’ and right around 18 degrees at 10,000’. While it’s not the over-the-hood conditions we’ve been used to the past few weeks, you can still find patches of soft settled powder in wind sheltered, shady terrain.


RECENT ACTIVITY

In his travels yesterday, Ted discovered a natural avalanche off the east side of Moffit Peak which occurred during last Tuesday’s storm cycle.

THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

It’s been pretty quiet on the eastern front and folks are getting’ after it, punching out bold lines in big terrain without incident. We haven’t seen or heard of any news of the weird and it seems that many of our old wind slabs are tired and lifeless. However, with winds increasing overnight they’re bound to find enough snow to blow around and form a new batch of wind slabs along the leeward side of upper elevation ridges. While today’s slabs are manageable you still need to get some information about the snows stability so you can decide where to ride safely. Test the snow on small slopes similar to what you want to ride. Pull on the dog’s tail a bit to see how it’s reacting before committing to a steep bowl or chute.


MOUNTAIN WEATHER

Periods of sun and clouds, gusty southwest winds and warm temperatures are all on tap for the region today. Southwest winds will be a nuisance along the ridges, blowing in the 30’s and 40’s. Highs at 8,000’ should reach into the low 40’s and at 10,000’ in the low to mid 30’s. Overnight lows bottom out in the mid 20’s. A westerly flow sets up for the beginning of the week, ushering in mild temperatures and a slight chance of light snow Monday and Tuesday. High pressure builds for the mid portion of the week. The computer models hint at a deep, cold trough for next weekend, but as you know that’s computer fantasy land and we’ll have to see how it all pans out. I’ll have a better handle on the storm track for the midweek update.


GENERAL ANNOUNCEMENTS

Remember- your observations help to save other riders lives. So if you see or trigger any avalanches please let me know what your seeing. You can reach me at 801-231-2170 or craig@utahavalanchecenter.org

Also, Beacon Basin is up and running and located inside the orange fencing on the northeast corner of the Nobletts Trailhead. In addition, Ted installed a Beacon Park in his neck of the woods, near the Bear River trailhead on the Evanston side of the range, so here's no excuse not to be practicing with your rescue gear.

The information in this advisory expires 24 hours after the date and time posted. I'll update this advisory by 7:00 am on Wednesday Mar. 18, 2009.
