Kernpunkte

Fresh wind slabs up to 12” deep will be our main concern today. East winds may be strong enough to actively load slopes so look for blowing snow. These may be easier to trigger and be a little larger than expected if they are sitting over buried weak layers. Wind slabs can be found about 2,500’ on steep wind loaded slopes, such as below ridges and in loaded gullies. 

SPECIAL ANNOUNCEMENTS:

SnowBall 2025 is this Friday! The Friends of the Chugach Avalanche Center and the Alaska Avalanche School are hosting the annual Snowball to celebrate another great winter season! There will be a silent auction, hors d’oeuvres, and live music from Wiley Post. All funds raised will benefit snow and avalanche safety in Alaska. Join us for a great night!

    Winds slabs up to 1’ deep  will be the main concern today above 2,500’. East winds are decreasing but may still be capable of moving snow into fresh wind slabs by the time you get out today. Blowing snow is a great clue that the winds are still actively loading slopes into fresh wind slabs. It is also likely that these wind slabs will be sitting over weak faceted snow that has been forming on the surface. When this happens wind slabs tend to be easier to trigger for longer and may produce larger than expected avalanches. 

    Wind slabs are typically found below ridge lines, on convex rolls, or in loaded gullies. Stiff snow over loose snow, and shooting cracks underneath you are clues you are traveling on a wind slab. Trying to trigger wind slabs on small inconsequential slopes is an excellent way to test the stability of the snow. Safer snow can be found on wind sheltered slopes.
