AVALANCHE ADVISORY

Tuesday, February 19, 20087:30 am
Good morning, this is Drew Hardesty with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Tuesday, February 19, 2008 and itís about 7:30 am.

 

Current Conditions:

Under clear skies and just shy of a full moon, winds are light from the northwest, running at speeds of 8-15mph with an occasional gust to 20.Stagnant and stable weather has mountain temperatures in the mid to upper twenties, with the lower elevation basins and drainages pooling temperatures into the mid-teens.Snow surface conditions remain best on sheltered shady slopes.With another beautiful day in store, youíll have another chance to check out new or wilder terrain in the mountains.

 

Snow and Avalanche Discussion:

Avalanche conditions are stable and the danger is mostly Low.Folks continued into more radical terrain yesterday, reporting welded-in wind drifts and only minor wet activity on the sun-exposed slopes.

 

The minor concerns for today will be two-fold.Beware the yawning glide cracks in Mill B South, Broads, and Stairs of Big Cottonwood canyon, as well as the Raymond slabs in Porter Fork.These glide cracks can release full-tilt at any time, and itís worth spending as little time underneath these as possible.Second, watch for the softening of the melt freeze crusts on the steep sun-exposed slopes in the afternoon and plan for safe exits there at the lower elevations.

 

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

The avalanche danger is generally LOW.Still, minor wet and dry sluffing may occur on the steepest slopes and the odd shallow wind pocket may be prodded, but these issues are only to create trouble if youíre in unforgiving terrain.

 

Mountain Weather:

Itíll be another beautiful day.Winds will remain light as they shift to the south and temps will rise to near 30 at 10,000í and the mid-30ís at 8000í.A few systems are on track, starting Wednesday through the weekend.The first will move south and hit central and southern Utah late Wednesday, with a more favorable storm track for Friday and again on Sunday.
