Good afternoon, this is Bruce Tremper with the
has been howling for the past 24 hours and the snow surface is a mess of hard
wind slabs and bare rock.† Itís so bad it
almost looks like
We have a storm getting cranked up as I type this and we expect it to lay down about a foot of dense snow overnight.† The snow that falls on bare ground should stick well but the snow that falls on northerly facing slopes above about 9,000í may have some problems.† First, you should carefully check how well the new snow is bonded to the old snow by digging down with your hand or jumping on small test slopes.† You will no doubt be able to find some sensitive wind slabs on steep slopes, so as usual, be suspicious of smooth, rounded wind pillows.† Second, there is no lack of rotten, weak, depth hoar that formed since snow first fell in mid October.† It exists on the aforementioned north facing slopes up high but it is quite pockety and variable. (Photo gallery of my field work) If we do get a significant dump of new snow on top of these layers, there may be a few booby traps around where you can trigger slides onto these deeper, weak layers.
The avalanche danger is generally LOW in most locations.† But it should rise to MODERATE danger by Saturday morning on northwest, north and northeast facing slopes steeper than about 35 degrees above about 9,000í in elevation. If we get more than about a foot of dense snow, the danger could rise to CONSIDERABLE on those same slopes.
The storm is ďcomplexĒ
as they say and we donít know exactly what will happen.† There is very moist air streaming in from the
southwest that should hammer southern and central
The extended forecast calls for much warmer temperatures for the rest of the week with a slight chance of more snow on about Wednesday.
