bottom line There is a LOW danger today, and avalanches are generally unlikely in the backcountry. Exceptions exist on steep drifted slopes at upper elevations and may develop on steep slopes where the surface snow becomes damp or saturated due to warming. Although rather unlikely, triggered avalanches are possible. Continue to use safe travel protocols, check your avalanche rescue equipment, and find the time to practice avalanche rescue scenarios with your partners....

current conditions The Tony Grove Snotel reports 15 inches of total snow, with 3.2 inches of water equivalent, and it's 31 degrees at the 8400' site. The 9700' CSI Logan Peak weather station reports west winds averaging in the mid teens and already 29 degrees this morning. Last weekend's dense snow did wonders for covering up the rocks, and we've been finding very nice and smooth shallow powder conditions above around 8000' where there is enough snow. Even with the dense snow from the weekend, you'll find generally very shallow early season snow cover in the Logan Zone. Recreation options are still limited to a few north facing upper elevation slopes with smooth underlying ground. It's still way too shallow for riding sleds in most areas without damaging equipment or the natural resource, but a few folks have been able to get out to test the tune-up on upper elevation roads and smooth meadows. Be sure to check your batteries in your transceiver and the working condition of your rescue equipment, practice rescue scenarios with your partners, and always follow safe travel protocols... Remember that the Tony Grove Road is not maintained for winter travel and is slick and icy on shady sections.. Be sure you are prepared with shovels and other emergency supplies.

description
Even though Sunday's snow was heavily rimed and moist., very strong, southwest wind formed stiff wind slabs in terrain exposed to wind .The potential of triggering stiff wind slabs exists in some isolated upper elevation north and east facing terrain... Some of these slabs may be sensitive to your weight on very steep slopes, and might fail on weak underlying October snow near the ground.... Avoid smooth, rounded, hollow sounding or chalky looking wind deposits on steep slopes... Hard wind slabs have a nasty habit of allowing people to get out on them before releasing. Warm temperatures in the mountains may cause the surface snow on some steep slopes to become moist or saturated, and loose wet avalanches may become possible in the heat of midday |

weather High pressure will continue into the weekend, with mild temperatures and a fair amount of sunshine expected today.. Expect temperatures in the forties above 8000' and a light southwest breeze. We'll see similar conditions tomorrow. The next weak storm will move into the area Saturday night, producing a good chance for an inch or two of accumulation at best on Sunday.. Next week's weather looks pretty benign , giving rise to fears of facets....
