bottom line Terrain to avoid- steep, upper elevation wind loaded terrain. The avalanche danger is CONSIDERABLE and dangerous human triggered avalanches are probable, especially in steep, rocky terrain where a solid feeling slab overlies thin, weak snow. A MODERATE danger exists at mid elevations and human triggered slides are possible LOW avalanche danger is found on wind sheltered slopes.

description
A weak and complex snowpack exists on the Skyline and avalanche conditions are deceptively tricky. Yesterday's new, light fluffy snow is hiding the dragons in the basement and the solid feeling base will lure us out onto steep slopes before it fails and we trigger a large and dangerous avalanche. You can avoid all this mess by heading to wind sheltered terrain or lower elevation slopes that had no snow prior to Tuesday's storm. |

description
Once initiated, today's shallow wind drifts can quickly get out of hand, breaking into deeper buried weak layers as they crash down onto the slope below creating a larger slide then you might've bargained for. |
 |
weather Clearing skies with daytime highs near 10 degrees. Northwest winds blow 15-25 mph along the ridges. Overnight lows bottom out to near -5 degrees. A warming trend develops tomorrow and we should see partly cloudy skies through Saturday. A weak storm slides into the region Sunday, but it doesn't look like a big snow producer. Not much agreement with the computer models for next week. |
