Urban Avalanche Advisory
Current Advisory as of
February 3, 2023
Expires 7:00 AM the following morning.
Issued By Tom Mattice
Primary Avalanche Problem
The current storm system started up on the 30-31st with 4" new snow and winds to se24 and se34 at Eaglecrest. Enough to drive some wind loading...
On the 1st we picked up another 2-4" snow this time with n28mph winds along the channel and ne27mph at Eaglecrest... once again not terribly strong winds and yet with new snow enough to drive some wind loading...
Yesterday we again picked up closer to 5" around the region again with winds to n41mph at the tram and ne22mph at Eaglecrest. More wind loading along the urban paths than on Douglas...
Coming into today another few inches of snow and se20mph winds along the channel with ese24mph winds on Douglas... still enough to continue loading and yet all of these events have been light on precipitation and moderate winds... but over this same time we built storm slabs up to 1' thick in places now... so you could have wind slabs of even greater size in the region that could potentially still be human triggered.
As we go into tonight and tomorrow conditions will dry out a little and temps will cool again decreasing danger levels over the next 24-36 hours. Winds tomorrow should also be mild... reducing avalanche danger over time.Learn more about Wind Slab.
Secondary Avalanche Problem
We see above for general details. The Storm slab is up to 1'+ thick in places now and today is calling for moderate winds, warming, and some precipitation... we do not expect to see natural avalanches occurring and yet should we see warming greater than forecast or more precipitation than expected we may see some level of natural activity... yet the current forecast is not calling for this...
At lower elevations today loose wet avalanches remain possible with todays warming and continued precipitation and yet once again, low in elevation and small in size.
As we go into tonight and tomorrow conditions will dry out a little and temps will cool again decreasing danger levels over the next 24-36 hours.Learn more about Storm Slab.
Today’s Avalanche Tip
Please recognize this is an urban advisory and not a full backcountry avalanche forecast. We try to discuss trends around the region but to head into the hills you need to be able to make your own educated avalanche decisions.
We recommend everyone playing in the backcountry take a level one avalanche course at minimum.
To understand more about the conditions in the backcountry in the region please go to the Coastal Alaska Avalanche Center at http://CoastalAkAvalanche.org to share your snow and avalanche observations.
Please do your part in sharing valuable information and remember as a community, the more we know, the safer the snow.
Be safe and enjoy a great day.
