As the snowpack gets comfortable in its own skin, the possibilty of triggering an avalanche that breaks to our persistent weakness (seen as the red line in the pit above) now buried 2'-3' deep in the midpack, begins to decrease... and that's good news, suggesting we're trending in the right direction. And while no avalanches were reported to us yesterday, it's only been a day since the last slide we know of broke to our midpack problem child. That said, I'm not gonna roll the dice and take my chances. No it's not a widespread issue, but the consequences remain serious. Once triggered, an avalanche breaking into these layers will quickly get out of hand and could instantly ruin our day. The most likely suspects are steep, wind drifted slopes facing north half of the compass. Fortunately with a little new snow, the riding conditions are improving on other aspects and we have more options on the table to avoid this avalanche dragon. Simply swing around to lower elevation slopes or choose low angle terrain with no steep slopes above or adjacent to where you're riding. (C.Brown photo)
Skies are clear, temperatures in the teens, and northwesterly winds are light, blowing less than 20 mph even along the high ridges. Monday nights little blast of winter stacked up nearly 4" of dense, spongy snow, greatly improving spirits as well as riding and turning conditions. Low angle, wind sheltered slopes are the ticket, where you won't bottom out to the old snow surface

A great body of recent trip reports, observations, and snow data are found here.
The slide above triggered Monday in Moffit Basin, clearly illustrates the type of avalanche dragon we're dealing with. Once initiated, today's avalanches will break deeper and wider than you might expect. (C.Brown photo)
Look for mostly sunny skies, light winds, and temperatures climbing into the upper 30's, as a mild northwest flow continues over the area today through Thursday. The flow becomes more westerly Friday and stronger with a mostly dry, cold front sliding through the region Saturday.
Today's shallow drifts are mostly manageable in size and you'll see them breaking at our below our skis, board, or sled. Found mostly on the leeward side of upper elevation ridges, I bet there's a slab or two lurking around a gully wall or entrance to a chute. In either case, today you'll want to look for and avoid any fat, rounded piece of snow, especially if it sounds hollow like a drum.
The information in this advisory expires 24 hours after the date and time posted, but will be updated by 7:00 AM Thursday February 8th, 2018.
It's also a good time to set up one of our very popular avalanche awareness classes. Reach out to me and I'll make it happen.
