AVALANCHE ADVISORY

Friday, March 23, 2007  7:30 am
Good morning, this is Brett Kobernik with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Friday, March 23, 2007 and it’s 7:30 in the morning.

 

Current Conditions:

Mountain temperatures were a few degrees warmer last night then the night before but still in the mid 20s and with clear skies overnight this should provide a decent refreeze of the upper snowpack.  Temperatures are slightly warmer in the Ogden and Provo area mountains with a number of stations above freezing.  Winds are from a westerly direction and fairly light.  Riding conditions remained pretty good yesterday with people still enjoying soft dry snow on the more northerly aspects.  The new snow has kind of loused up the corn but if you go to areas that didn’t receive much snow out of the last system chances are better for a supportable surface.  Otherwise you’ll find breakable crusts this morning on aspects that were sun affected over the last few days.

 

Snow and Avalanche Discussion:

Things were fairly quiet in the backcountry on Thursday as far as avalanches were concerned.  There were a couple of glide avalanches in Broads Fork which is not surprising for this time of the season.  Also, you could initiate small push-a-lanches with slope cuts on sun exposed aspects that would entrain the new snow.  (see Photos link on the left)  These could get big enough to knock a person over causing injury if they run on a sustained enough slope.

 

The main concern for today will be heat related activity mostly within the new snow as the day progresses.  East facing slopes warm first, then south, then west.  Avalanches releasing deeper into the snowpack will be fairly unlikely but you will still want to watch sunny aspects to become punchy.  If this happens, it’s time to move off of them as this is a sign that the snow is becoming weak.

 

Bottom Line for the Salt Lake, Park City, Provo and Ogden area mountains: 

The avalanche danger will go from LOW to MODERATE on slopes steeper than about 35 degrees as daytime heating occurs.  Clouds this afternoon may keep temperatures in check and not allow slopes to become total mush which will help keep the avalanche danger at bay.

 

Mountain Weather: 

Skies will start out mostly clear this morning with increasing clouds through the day.  8000 to 10,000 foot ridgeline temperatures will be a few degrees warmer then yesterday and reach into the mid 40s.  Ridgetop winds will pick up slightly for a while but only into the 10mph range gusting to around 30 at the more exposed locations from a northerly direction.  For the weekend we’ll see partly cloudy skies with gradually increasing daytime temperatures and southwest winds picking up on Sunday.  There will be a disturbance that will bring the chance for rain or snow showers late Sunday then the next good chance for a colder snow storm will be Tuesday into Wednesday which looks fairly decent still at this time.
