Above 8,500 ft.
7,000-8,500 ft.
5,000-7,000 ft.

bottom line There is a MODERATE danger today. Heightened avalanche conditions exist and you could trigger new snow or wind slab avalanches on steep upper elevation slopes. Evaluate the snow and terrain carefully, especially on upper elevation slopes with preexisting snow. The danger of wind slab avalanches will increase or become more widespread tomorrow, with intensifying winds in the forecast.

current conditions Well, I wouldn't really call it a powder day, but there is a bit of fresh heavy snow at upper elevations this morning. The Tony Grove Snotel reports 4 inches of heavy moist snow containing 7/10ths of an inch of water from yesterday and overnight. The site reports 18 inches of total snow, and it's still pretty warm, 34 degrees at 8400' . Southwest winds gusted into the 40s at the CSI Logan Peak weather station early this morning, and its 30 degrees up at 9700'. The Tony Grove Road is not maintained for winter travel and was very slick and icy on shady sections before last night's snowfall. Be sure you are prepared with shovels and other emergency supplies if you attempt the drive. There are lots of pedestrians and dogs on the upper portion of the road these days, so please keep an eye out and the speed down.

description
Heavy moist snow and sustained southwest winds caused heightened avalanche conditions on steep slopes at upper elevations.. The moist new snow may not bond so well with the loose sugary snow that was on the surface in many areas before yesterday. Triggered loose sluffs and shallow soft slabs are possible in steep terrain...

description
South and west winds deposited snow on the lee side of ridges and in upper elevation deposition areas, and you could trigger wind slab avalanches up around a foot deep on steep drifted slopes. Strong and intensifying winds tomorrow will cause the danger of wind slab avalanches to rise or become more widespread... |

weather A windy, moist, and mild southwest flow will persist through the weekend. A few inches of heavy moist snow accumulated at upper elevations last night, and a similar but slightly stronger disturbance is expected Sunday night. Keep you fingers crossed, since even a few inches of snow will help our dire backcountry situation... Strong and intensifying southwest wind ahead of the next front will be the big player on Sunday, with gusts near 50 mph expected. Snow will start up again tomorrow and a foot of fresh snow may accumulate on upper elevation slopes by Monday morning... Check out the Logan Mountain Weather page...
