Avalanche advisory

Monday, March 08, 2004,   7:30 am

 

Good morning, this is Drew Hardesty with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Monday, March 08, 2004, and it’s 7:30 a.m.  This forecast is brought to you in partnership with the Friends of the Utah Avalanche Center, supported in part by Black Diamond equipment.

 

Current Conditions:

After yesterday’s skyrocketing temperatures into the mid and upper 40’s up to 9500’, today will be round two of Beach Blanket Bingo with even warmer temperatures expected.  There was only a slight cool-off overnight with inverted temperatures as overnight lows dropped to 30 and 21 degrees at 10,000’ and 7000’, respectively.  The winds seemed to have blown themselves out and have been less than 10mph from the northwest.  While the conditions were described as “sublimely miserable” by a friend of mine, you can still find decent creamy powder on mid elevation sun and wind protected slopes.   

 

Avalanche Conditions:

Just like clockwork, the sunny aspects went off yesterday and some of the steeper and longer running south facing shots had impressive wet debris piles under them.  Not to be left out, the lower elevation north facing slopes also got in on the action as ambient heating on cold snow produced decent debris piles, perhaps most notably in Ogden and Weber canyons.  On the other side of the coin, there were at least three skier triggered avalanches in the backcountry, with one natural slide, presumed triggered by cornice fall.  The skier triggered slides were in No-Name bowl, off the Park City ridgeline, that was reported to be 2-4’ deep and 100’ wide (notice the relationship between what naturally slid Saturday in West Monitor with what was human triggered yesterday); a steep northeast facing rollover in upper Snake Creek at 8500’ that was 8” and not very wide; and a report of a skier triggered slide in Toledo Chute that left a decent debris pile down in the transition zone.  The natural was on a south facing aspect near the Red Rock cliffs area on the Park City ridgeline that broke 1’ deep by 100’ wide.  

 

It’s likely that most of the instability from Saturday’s strong winds has settled out, but you may still find a remnant wind slab that you could get to pop out in the odd nook or in steep rocky terrain that has a shallower snowpack.  Wet activity will be the primary focus for today, however, as the poor refreeze and warmer temperatures will set the stage for continued problems on the steep sun exposed slopes.  The wet activity on the north facing slopes will undoubtedly notch a bit higher in elevation, perhaps to 8000’.  So again, if you’re sinking in up past your boot-cuffs, dodging rollerballs and pinwheels, or getting wet push-alanches to pull out on the steeper slopes, it’ll be time to head to a different aspect or back to the car.  Finally, cornices will likely be more sensitive today as well.

 

Bottom Line for the Wasatch Range, including the Salt Lake, Park City, PROVO AND OGDEN AREA MOUNTAINS:

The avalanche danger is generally LOW with just isolated areas where you could pull out an old wind slab.  The danger of wet avalanche activity will rise to MODERATE on the steep sun exposed slopes and may again rise to CONSIDERABLE, particularly on slopes that didn’t manage to release yesterday.

Mountain Weather:

We’ll see continued bluebird skies and light northerly winds.  8000’ temps will be in the mid forties with 10,000’ temps rising again to the mid to upper thirties.  Tomorrow will be just as warm with a dry cold front expected for Wednesday.
