Don’t forget your down jacket, mittens, and thermos today. Moderate Northwest winds (15-30mph) and single digits (F) temperatures could easily bring the windchill factor near -20F, especially in the upper elevations. These same winds could also be adding stress to an early season snowpack. Watch out for isolated windslabs near ridges or a wind slab that could be sitting on the Nov 16 layer of buried surface hoar. If this is the case, a ‘typical’ wind slab avalanche could step down and trigger a much larger slide releasing 2-3′ deep. Keep in mind, these could pop out mid-slope. Be aware of your exposure and avoid pillow shaped snow on steep unsupported terrain features. Snow that feels supportable, hollow or drumlike is suspect and cracking will be an obvious sign that this snow is unstable.
Be prepared for cold weather, travel one at time between safe zone, and adjust your plans if an area becomes too crowded.
A normal weekday on the popular ski track up Sunbursts SW shoulder. Photo taken yesterday, Dec.2 at 12:30pm.
A layer of buried surface hoar, 1-3′ deep, still remains on many slopes throughout Turnagain Pass and in the Summit Lake area. During the past two weeks, many popular slopes have avalanched (removing the weak layer), and been covered again by recent snow. This makes it really hard to know the full extent of which slopes still have this weak layer set-up, especially in places that haven’t seen much traffic.
Keep these questions in mind today before committing to a route or descending:
It’s been roughly a week since we have seen or heard of a glide crack releasing – but the cracks continue to widen despite the cold weather. Once again, limiting your exposure under these is highly recommended.
Yesterday was mostly cloudy with temperatures in the low to mid 20F’s. A generally NW wind direction was recorded at ridge tops. Sunburst weather station recorded light NW winds while Seattle Ridge weather station experienced sustained moderate winds (15-25mph.)
Overnight temperatures have been falling into the single digits in the upper elevations and low teens (F) along the road corridor. No new precipitation was recorded in the last 24 hours.
Today looks similar. Temperatures should remain in the single digits with a high of around 10F at lower elevations. Northwest Ridgetop winds are expected to remain moderate (15-25mph) with a chance of isolated snow showers in the afternoon.
Northwest flow are expected to bring cold arctic air and moderate ridgetop winds to Southcentral, Alaska throughout the weekend. Anticipate clear skies tomorrow.
