Alyeska picked up 37cm of fresh snow, while Arctic Valley added 18cm, giving Alaska a solid early-season boost.
Alyeska took the headline, receiving 37cm of fresh snow and the largest single dump among qualifying resorts. That amount has noticeably improved mid and upper mountain coverage and has already created well-defined powder lines around the tram and higher bowls. Conditions feel early-season cold and dry where the snowfall landed, which helps preserve the new snow rather than letting it rut quickly. For mid-November this is a meaningful fill, not a storm that merely dusted the slopes.
The rest of the qualifying picture is exclusively Alaskan. Arctic Valley added 18cm, enough to pepper its steeper aspects and boost terrain off the lift network. Between Alyeska and Arctic Valley, Alaska owns the day; no other North American or international resorts met the qualifying threshold in this update. Those two resorts together indicate a focused, regional event rather than a wider storm cycle. Ski areas with little or no fresh snow should not expect the same kind of coverage, so travel will reward those heading to Anchorage-area mountains this week.
The new snow at both resorts is already doing the work of base building, with the freshest deposits most obvious above tree line. Absent additional forecast data in this report, current conditions suggest pockets of rideable powder will remain through the next 24 to 48 hours at higher elevations, provided temperatures stay cold. If a warming trend appears, expect quicker settlement and some surface consolidation. For anyone planning a short trip to Alaska now, both Alyeska and Arctic Valley offer the best odds for fresh turns in this update.
