Avalanche Advisory
Advisory: Skyline Area Mountains Issued by Brett Kobernik for Monday - January 18, 2016 - 7:04am
bottom line

The majority of the terrain out there has a LOW to MODERATE avalanche danger. The avalanche danger is more pronounced along the upper elevation east facing terrain especially along and just below the ridges. Avoid any obviously large drifts that are on steep slopes. Hill climbing and high marking in the upper elevation east facing steep slopes is the most likely way to trigger an avalanche today.




current conditions

Wind on Sunday makes the headline today. It picked up and blew from the northwest transporting snow and forming cornices along the higher ridges. It was blowing hard enough to get down into the mid elevations and stir things up as well. It did slow down late in the afternoon. There is still a little breeze and the direction is starting to shift to the southwest. Temperatures are quite mild out there this morning in the upper 20s in the higher terrain.

recent activity

Some of the cornices that were forming on Sunday broke off naturally and triggered small pockets below them also. These in the photo below were the largest ones that I came across. I suspect there may have been some that were bigger.

description

You will again want to avoid the big east facing steep bowls and watch for cornices and large drifts along the ridges today. The southwest wind will probably transport some more snow today. These fresh drifts will be more stubborn and harder to trigger today but some of them are going to be large enough to be dangerous. These will be more unpredictable than on Sunday as to which ones will release.

weather

We'll have mostly cloudy skies today with mild temperatures and west southwest wind blowing in the moderate speed category. It may be slightly gusty along the upper ridges. A storm will move in later today and snow is possible this afternoon. it looks like most of the snow will fall tonight. It's looking like we'll pick up 3 to 6 inches by Tuesday morning. The long range still looks active but none of the storms look real big. Another one will move through on Wednesday and then another is being advertised for Saturday.
