With light to moderate winds out of the south over the last 24 hours, new thin wind slabs have developed in the upper most terrain on the north half of the compass. These new wind slabs should be managable due to their small size and ease of being triggered. However, in steep exposed terrain, even a small wind slab could knock you off your feet.
My main concern today will be triggering an older stiffer wind slab. These older wind slabs can be 1-3 feet deep and in some areas where the snowpack is thinner (wind scoured/rocky) lie above thin sugary snow. Luckily, they are fairly easy to pick out due to the hard hollow feel of the snowpack. Before you get to a slope, anticipate where slabs may lie - use cornices, and wind pillows as clues.
With warming temperatures, light winds, and no new precipitation avalanche conditions are improving throughout the area. However, we are still tracking several weak layers that were scattered throughout the advisory areas snowpack before last week's warm and windy storm.
**Before committing to skiing or riding a slope over 30 degrees on the north half of the compass today, take a moment to dig into the snow and see if a thin grey line (buried surface hoar) is buried one to two feet below the snow surface. If so, look elsewhere to ski and ride.

Snowmobiler/Snowbiker Travel Restrictions: a quick reminder that the Granite Mountain Area Closure is now in effect. In addition there are other areas on the Payette National Forest that are CLOSED to snowmobile traffic including Jughandle Mt east of Jug Meadows, Lick Creek/Lake Fork Drainage (on the right side of the road as you are traveling up canyon), and the area north of Brundage Mt Ski area to junction "V" and along the east side of Brundage and Sergeants' Mts. with the exception of the Lookout Rd( junction "S"). Please respect these closures and other users recreating in them. Winter Travel Map(East side). You can download the map to the AVENZA app on your phone, and know your exact location while you are out riding.
We had reports of loose wet avalanches that slid late on Saturday afternoon on solar aspects in the upper elevations.

Over the last 24 hours at the Granite Mountain weather station, we have had no new snow, and light to moderate winds out of the south, southwest, and southeast. Today the forecast is calling for a high in the low 30's with winds blowing in the teens. Tonight we will have the arrival of a low from the Gulf of Alaska. Clouds and winds will be increasing after 11 pm tonight, however, snow will not begin to fall until Tuesday during the day. Tomorrow, daytime totals in the mountains will not bee too impressive with only 1 to 4 inches on tap. We do have a chance of precipitation each day through the work week and into the weekend in the mountains.
