Turnagain Pass Avalanche Forecast
Good morning. This is Wendy Wagner with the Chugach National Forest Avalanche Information Center on Sunday, November 20th at 7am. This will serve as 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).
The avalanche danger is generally LOW with pockets of MODERATE for fresh wind slabs and new snow sluffing. These concerns are most likely on steep slopes above tree line in locations that receive a few inches or more of new snow. Pockets of MODERATE danger also exist for glide avalanches on slopes with recent glide activity.
Today we should see a few inches of new snow in the Girdwood, Turnagain Pass and Summit Lake areas. At the upper elevations, winds are strong enough to form fresh wind pockets and small slabs in any new snow accumulating through the day. Areas most prone to wind slab avalanches will have a hard old layer underneath providing a slick bed surface for these to run on. Additionally, in locations lucky enough to receive several inches of snow, watch for fast running sluffs on slopes with a firm old surface.
The glide avalanche problem remains a wild card. It seems the cycle is beginning to abate but is not finished. Savvy travel in areas with glide activity and yawing glide cracks should continue. These areas are ‘ok’ most of the time, but when they’re not, they’re not. Exposure around and under any suspicious areas should be limited.
MOUNTAIN WEATHER ROUNDUP
A low developing in the western Gulf of Alaska has shifted the flow easterly and warmed temperatures into the double digits overnight at most locations. Winds have been moderate from the east, gusting around 25mph on the Ridgelines. No snow has been reported by 6am but should start to fall later this morning. Accumulations are expected to be minimal, 1-3 inches, though possibly more in favored locations. Temperatures will be in the teens today but again drop to the single digits Monday. Skies will remain cloudy and winds are expected to be around 20-30mph on the ridgelines from the east.
