The avalanche danger is LOW today in the alpine and treeline elevations. New snow falling througout the day will build very small and isolated pockets of slab up to 6″ deep in upper elevation leeward starting zones. Below treeline there is minimal snow cover and travel on skis or a board is not recommended.
Early season hazards-rocks, stumps, and a slick crust require careful travel in the mountains today.

Travel Advice | Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features. | Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern. | Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding, and conservative decision-making essential. | Very dangerous avalanche conditions. Travel in avalanche terrain not recommended. | Extraordinarily dangerous avalanche conditions. Avoid all avalanche terrain. |
Likelihood of Avalanches | Natural and human-triggered avalanches unlikely. | Natural avalanches unlikely; human-triggered avalanches possible. | Natural avalanches possible; human-triggered avalanches likely. | Natural avalanches likely; human-triggered avalanches very likely. | Natural and human-triggered avalanches certain. |
Avalanche Size and Distribution | Small avalanches in isolated areas or extreme terrain. | Small avalanches in specific areas; or large avalanches in isolated areas. | Small avalanches in many areas; or large avalanches in specific areas; or very large avalanches in isolated areas. | Large avalanches in many areas; or very large avalanches in specific areas. | Very large avalanches in many areas. |
With forecasted snow amounts in the 2-4” range, expect your main issue to continue to be early season hazards. This new snow will come to rest on a layer of weak snow, but is not quite enough to warrant heightened concern. Keep in mind that LOW danger does not mean ‘no’ danger.
Be on the lookout for isolated pockets of slab in the higher elevations to build to a max depth of 6” today. These slabs will be scattered in favored locations and not continuous enough to be a significant issue.
Loose snow sluffing is also possible in very steep terrain. 4-8″ of older low density snow on the surface has shown to be well bonded to the crust below. There is still the chance of finding areas on slopes over 40 degrees where sluffing of the new & old snow could be a concern. As with the isolated pockets mentioned above, any sluffs that might be triggered will be very low in volume.
It has now been a full week since the last measurable snowfall in the mountains. Winds have remained generally calm during this period as well. Temperatures have been more winter like allowing for preservation of the snow that sits on the ground.
Today a weakening Low pressure system is bringing moisture from the Southwest. The orientation of this band of precip will favor Hatcher Pass and Anchorage. Turnagain will receive the leftovers; enough to drop 2-4 € of snow in the mountains. Winds will be light out of the Southeast at 5-10 mph. Temperatures at 1,000′ will be in the low 30s F while ridgetops will be in the mid 20s F.
Snow should taper off by tonight as a short lived ridge of high pressure will build into the area. The extended outlook points to more precip in the form of snow as we head into the early part of next week.
