Good morning, this is Tom Kimbrough with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Friday, November 22, 2002, and itís 7:30 am.

 

Current Conditions:

Itís hard to believe its November.We have had great spring conditions for the past couple of days and more of the same is in store for today.Mountain temperatures are in the mid to upper 30ís this morning.Highs yesterday got into the upper forties even at 10,000 feet.Ridge top winds are 5 to 15 from the west.

 

The groomers at the just-opening resorts are excellent skiing and boarding in fine springlike snow.In the backcountry, the plethora of rocks, bushes, sun and wind crusts and general deficiency of cover are, shall we say, challenging but there are a few patches of decent recrystalized powder on slopes sheltered from wind and sun.Snowmobiling is limited to mid and upper elevation roads and trails.Snowshoes are a good choice for enjoying todayís May-like weather in the mountains.

 

Avalanche Conditions:

It seems too early in the season to be talking about wet slides but that has been the only recent avalanche activity.These wet point release slides were on southerly facing slopes, above 9,000 feet and were mostly associated with rock bands that heat up under the sun.Today will again be warm and there was not a good overnight re-freeze so when the snow starts to get wet and sloppy later this morning, get off of and out from under steep, sunny slopes.

 

There is also a slight chance of triggering a deeper hard slab avalanche on the old October depth hoar or an old wind drift.Please continue to use caution on steep, mid and upper elevation shady slopes.

 

Bottom Line (SLC and Provo Area Mountains):

The avalanche danger is generally LOW this morning but may rise to MODERATE on steep sun exposed slopes as temperatures increase.Pockets of MODERATE avalanche danger remain above about 9,000 feet, on very steep northeast, north and northwest facing slopes.

 

Ogden and Logan Area Mountains:

The avalanche danger is generally LOW.

 

Mountain Weather:

This is probably our last day of this unseasonably warm weather.Skies will be mostly sunny this morning with increasing high clouds this afternoon.High temperatures today will again get into the upper forties in the mountains.Winds will increase later today to 10 to 20 mph from the southwest.Overnight lows tonight should cool to near thirty under mostly cloudy skies.A weak but cool storm system will arrive Saturday with a chance for a few inches of new snow.Sunday and Monday should continue more November-like with cool, showery weather under a moist northwest flow.None of this looks like the big dump we need but at least itís a change in the right direction.
