Danger Rose Tutorial

Saturday's instabilities with the high precipitation rates now seem long ago. The overall danger is LOW, unless you count the prospect of ruining gear or your body on the thin coverage out there. One observer wanted a skull and crossbones for the south and westerly aspects for this - perhaps a new icon?


Reminder! It's the new moon and all the old avalanche forecasters from Tennessee recommend catching your first glimpse of it with nothing in your hands. Worked well for Kimbrough to keep him mostly out of trouble for years. Skies are clear under the small dome of high pressure. The stagnant weather has light winds, freezing temperatures at the highest elevations and cooler air filtering into the mountain valleys and basins. The Thursday/Saturday storms have settled to 5-8" with overall depths ranging from 1-2'.....Coverage is threadbare at best with rocks and stumps awaiting every turn.

Please extend courtesy to the barely opened and unopened ski areas as they hustle to get their winter operations in place. Remember too that they are not doing any avalanche control so treat in-bounds familiar terrain as the backcountry.

Saturday's instabilities seem like a thing of the past and all the wind whales up high are welded in place. Not that there isn't anything happening in the snowpack: high pressure will facilitate the continued development of surface hoar and weakening of the snow surface. Weakening snow abounds above the old October crust and just beneath the wafer thin crust on the surface prior to last Thursday's storm. My field day yesterday into upper Big Cottonwood. Spatial variability of the snowpack is pronounced in the early seasons - this year is no different.


We'll have clear skies, light winds and warm mountain temperatures. 8000' and 10,000' temps will be in the 40's and 30's, respectively. Increasing southwesterly winds tonight will usher through a weak cold front for tomorrow afternoon - we should see at best a few flakes and allow the inversion to mix-out. High pressure rebuilds, albeit briefly, ahead of two storms for the weekend.
