Avalanche advisory

MONDAY, DECEMBER 1, 2003   7:30 am

 

Good morning, this is Drew Hardesty with the Forest Service Utah Avalanche Center with your avalanche and mountain weather advisory.  Today is Monday, December 1st  2003, and it’s 7:30 a.m.  We will be giving two free avalanche awareness talks this week – one at the Salt Lake REI, Tuesday, December 2nd at 7 pm and one at Kirkham’s, Saturday, December 6th, at 7pm.

 

Current Conditions:

Under partly cloudy skies, mountain temperatures are slightly inverted, with upper elevation temps in the mid and upper thirties and rising.  Lower elevation areas in the drainages and basins are reporting temperatures in the twenties.  Winds are in the teens, with some of the more exposed wind stations in the 20-25mph range out of the southwest.   Snow surface conditions change significantly with elevation.  At the mid and low elevation areas, you’ll encounter breakable crusts that may soften by midday, while northerly slopes above about 9500’ have dense powder with a thin overlying crust that you can boss around.

 

Avalanche Conditions:

Minor wet activity was again the only action in the mountains yesterday. Today, you can throw sunny skies into the mix along with the poor refreeze and tropical mountain temperatures to hasten and increase the wet activity.  While I am not expecting wet slabs to release, be alert for wet sluffs to gain momentum and mass on the steeper slopes.  Best to avoid being knocked off your feet or machine or ending up in the bottom of a terrain trap with wet debris coming down on top of you.

 

Bottom Line (Salt Lake, Park City, Ogden and Provo area mountains):

The avalanche danger is LOW in all areas with the exception of a MODERATE danger of increasing wet activity today due to a lack of a decent refreeze, continued warm temps, and increased solar radiation. 

 

Mountain Weather:

We’ll see mostly sunny skies with continued warm mountain temperatures.  8000’ temps will get up into the mid-40’s, with 10,000’ temps rising to the mid and upper 30’s.  The winds will increase out of the southwest today into the 15-25mph range ahead of a weak storm arriving early tomorrow morning.  The front should produce a couple inches, but cool mountain temperatures off by about 10-15 degrees.  A ridge builds in behind the disturbance for Tuesday afternoon, with partly cloudy skies through the rest of the week.  The longer range models suggest another storm on tap for the weekend.
