|Travel Advice||Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.||Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.||Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding, and conservative decision-making essential.||Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.||Extraordinarily dangerous avalanche conditions. Avoid all avalanche terrain.|

Winds out of the East coupled with 8-10” of new snow in the higher elevations have created slabs that will be easy to trigger this morning. These slabs will range in depth from 10-14”. With more snow and wind in the forecast, expect these slabs to increase in depth and sensitivity. These slabs will be most sensitive as they are forming.
With winds blowing predominantly out of the East, it is safe to assume that West aspects will be wind loaded today. However, as wind interacts with terrain, it often changes direction. Because of this it is important to learn how to recognize wind loaded terrain features. Look for smooth, rounded and pillowy surfaces. Shooting cracks are commonly found on wind loaded features and are an obvious sign of unstable snow.
Avoiding wind loaded areas will be your best bet for managing this avalanche concern today.
Rain and above freezing temperatures have and will continue to create weak surface snow. In terrain over 40 degrees in the lower elevations be on the lookout for human triggered wet loose avalanches to move slowly. There is potential for these to gain enough mass to knock a person over and increase chances for injury. If you are sinking more than a few inches below the surface, it is time to back off of steep terrain.
In the past 24 hours 8 € snow containing .8 € of water have fallen at the Center Ridge SNOTEL site. Rain/snow line has fluctuated between 500′-1,800′. Winds have been blowing steadily out of the East, with Sunburst averaging 25 mph (max gust 49 mph). Temperatures at ridge tops have been in the mid 20s F (Sunburst 24 hr avg=23.2 F)
Today expect more precipitation, with the bulk of it arriving later in the day. As much as 5 € of additional snow can be expected by sunset. Winds will continue to be in the moderate range, 25-35 mph out of the East. Rain/snow line should hover around 1,500-1,800′. Temperatures at 1,000′ will reach into the low 40s F.
Unsettled weather will persist through the weekend. Moving into the early part of next week drier conditions should take over as the Low currently stalled over the area makes an exit.
