ARCHIVED ADVISORY - All advisories expire after 24 hours from the posting date/time.
The avalanche danger is MODERATE today. We got a healthy refresh of new snow yesterday with up to 1 foot of snow in some areas. The danger rating will stay elevated today because of some uncertainty in how the dry snow with some wind is behaving. I expect generally low hazard below treeline and in sheltered areas. Above treeline, tender windslab and loose snow avalanches are possible.
The thousand-dollar question today is, How much snow and how much wind did we get yesterday? Most of our region received a modest 6-8 inches of light dry powder. We measured up to 12 inches around the Portage highway, and over in Valdez and Cordova the snowfall is being measured in feet.
The avalanche problem should continue to be mild and predictable today. Watch for stiffer pockets where the wind has blown the new surface snow. Higher elevations, rollovers, and ridge transitions are the most likely areas to find surface instability. Avalanche size potential will be small and limited to the new snow only.
Im expecting that most of our forecast area simply got improved riding conditions. With that being said, we have limited information on how the new snow is reacting, so approach the fresh snow with some stability questions in mind until you know what sort of danger exists.
Snowfall yesterday was 6-8 inches in most areas and 1/2 inch of water equivalent covered our region. Wind was reaching into the 30s and 40s during the beginning of the storm, but it gradually decreased during the day. Temperatures rose into the 20s mid day yesterday and dropped back into single digits overnight.
Expect mostly sunny skies this afternoon. Temperatures may rise into the teens, and wind will remain light with local gusts to the high 20s at upper elevations. Significant snow is back in the forecast for the weekend, stay tuned for more information on the approaching storm.

This is a general backcountry avalanche advisory issued for Turnagain Arm with Turnagain Pass as the core advisory area (this advisory does not apply to highways, railroads, or operating ski areas).
Riding status is not associated with avalanche danger. An area will be open to motorized use in accordance to the Forest Management Plan when snow coverage is adequate to protect underlying vegetation. Backcountry hazards including avalanche hazard are always present regardless of the open status of motorized use areas.
