December 08, 2006† 7:30 am
Good morning, this is Brett Kobernik with the
Overnight, ridgetop temperatures remained in the upper 20s while ridgetop winds shifted to the south and picked up slightly but still just blowing around 10 mph with gusts into the 20s at the most exposed locations.†
Snowpack and Avalanche Conditions:
Itís another day without much to talk about as far as the snowpack is concerned.† Weakening surface snow; more areas becoming unsupportable; potential persistent weakness; blah blah blah.† Unfortunately, we will need to pay attention to this snow for a while after it gets covered up.† We may not see immediate results after the next snow storms but we know that this current snow is a major red flag.† By Monday we could have a slab sitting on top of our weak snow.† Once this weak snow is buried, just knowing itís there is enough to demand a VERY cautious approach to steep terrain.† (Click here for some field observations)
It is pretty hard to find any snow that will crack and propagate right now.† The only place this may happen would be in wind affected terrain along the ridges where a small wind slab may crack.† This poses very little threat.† Sluffing can be a small issue as well.† Yesterday, I watched my partner Evelyn ski through a chute where the loose faceted snow was sluffing almost completely covering her tracks.† This could potentially knock you over but thereís little chance for burial.
The avalanche danger is mostly LOW today.† Low danger does not mean no danger.† There may be a few lingering wind slabs up high and you can also get a few sluffs going on the steeper northerly facing slopes today.†
The upper level high pressure ridge starts to move east this afternoon so skies will remain mostly clear in the mean time.† Ridgetop temperatures will be in the mid to upper 30s with southwest winds in the 10 to 20 mph range gusting into the 30s at the most exposed locations.
A series of progressively stronger storms starts to affect our area Saturday.† The first wonít produce much snow but the next two look like better chances.
