The Bottom Line

Good morning, this is Wendy Wagner with the Chugach National Forest Avalanche Information Center on Monday, November 14th at 7am. This will serve as a general backcountry avalanche advisory issued for Turnagain Arm with Turnagain Pass as the core advisory area (this does not apply to highways, railroads, or operating ski areas).

Our next advisory will be issued Wednesday November 16th at 7am. In the meantime, keep checking our photos/observations page for new submissions.

AVALANCHE DISCUSSION

The glide avalanche problem perseveres. Over the past 7 days, 5 days have had documented glide avalanche occurrences, in many cases more than one per day. To date, two separate touring parties have had ‘too close for comfort’ calls with these creatures. Those accounts are HERE and HERE.

The fact is, these glide avalanches are releasing where we are recreating, and releasing spontaneously. Many folks have been enjoying our great early season snowpack, yet being in the wrong place at the wrong time could have very high consequences. Be aware of what is above and near you and limit exposure to suspect areas such as runout zones and cracks. Though not all glide cracks fully release and avalanche, there is no way of knowing which will and which will not. Furthermore, a glide can release without a visible crack present. Hence, all cracks and suspect areas (i.e., broad slopes, shoulders and rollovers above gullies) should be respected.

As far as the layering in the snowpack, the new snow from over the weekend has bonded well with the old snow surface. Generally speaking, the pack in the Turnagain area has a ‘right side up’ structure. This is good news, however, watch for lingering pockets of wind drifts and wind slabs. These will likely still be possible to trigger off ridgelines, over rollovers and near gullies.

For Tuesday, the avalanche conditions are trending the same.

MOUNTAIN WEATHER ROUNDUP

The winds that blew over our region yesterday were best represented by the Seattle Ridge weather station. Gusts well over 40mph were seen in many locations and the upper elevation exposed slopes are severely wind damaged. Temperatures slowly dropped throughout the day and are currently sitting at 7F on the Sunburst Ridge (3812′) and 15F on Center Ridge (1880′) this morning. Today, one last weather disturbance moves through from the west that will bring a chance for a trace of snow, moderate NW winds and reasonable temperatures. On its heels, a ridge of high pressure will build in Tuesday giving us clear skies and sending even colder air our way. Temperatures will be in the single digits for mid-week.
