Alaska's forecasters are calling for above normal snowfall along the coast as a Super El Nino builds, and the roads that carry the state through winter sit right under it.What the Outlook SaysWhat the Outlook SaysThe National Weather Service office in Anchorage has built its 2026-27 outlook around El Nino: above normal temperatures across southern Alaska and the Aleutians, above normal precipitation and snowfall along the coast, near normal elsewhere. The broader seasonal outlook for January through March runs warm across the state, and the event itself, which researchers at the Columbia Climate School say is already showing the classic early warning signs of a Super El Nino, has an 81 percent chance of reaching very strong intensity between October and December.AdvertisementAdvertisementNOAA's snow map of El Nino winters draws the driver's line: the coastal mountains of Southcentral and Southeast run blue, more snow than average, while most of the Interior runs brown. The snow concentrates where the traffic does.One caveat and done: the last strong El Nino winter, 2023-24, ran colder than expected and still buried parts of southern Alaska. The pattern shifts the odds, it does not sign a contract.Where the Snow Piles UpRoad / PassWhat the Outlook Points ToWhy It MattersThompson Pass, Richardson HighwayDeepest blue zone on the El Nino snow map, above normal coastal snowfall in the Anchorage outlookSnowiest recorded place in Alaska and the only road into Valdez; steep grades, avalanche terrain, chain territoryTurnagain Pass, Seward HighwayCoastal mountain corridor in the above normal snow zoneMain route out of Anchorage to the Kenai; heaviest traffic of any mountain pass in the stateGlenn Highway to Eureka SummitAbove normal snow on the climbs, freeze-thaw at lower elevationsAnchorage's link to Glennallen and the Interior; long exposed grades that hold iceHatcher Pass RoadHigh terrain in the blue zoneRecreation traffic all winter; closes to through traffic but the access sides stay busyParks Highway and the DaltonBrown on the map, less snow than average but full Interior coldLess fresh snow does not soften minus 40; the cold side of the split, not the safe sideThe pattern is simple: the snow surplus lands on the passes within reach of Anchorage, which is exactly where Alaska's winter traffic already is.Blue shows more snow than average during El Nino winters, brown shows less.

AlaskaNOAARelated: Super El Nino Map Shows Where Drivers Face 'Significant Snow' This WinterHow Drivers Should Play ItThe preparation is the same one the calendar already demands in Alaska, just aimed at a different mix. An El Nino winter trades some of the deep cold for surfaces that keep changing, and that is a harder problem than plain snow.AdvertisementAdvertisementStart with the rubber. Studded or dedicated winter tires by the fall changeover is standard practice in the state, but this year the studs earn their keep: ice, glaze and rain-on-snow reward metal more than deep powder does, and those are exactly the surfaces a warm winter produces. Book the changeover early, because the first freeze fills every tire shop in Anchorage within a week.Then respect the freeze-thaw clock. When daytime temperatures crest above freezing and drop back after dark, the danger window is the morning after the warm day, not the storm itself. A road that was merely wet at 4 p.m. is glare ice at 7 a.m., and the climbs hold it longest: Turnagain Pass, the Glenn grades toward Eureka Summit, and every shaded curve in between. Treat any warm day that follows a storm as an ice morning waiting to happen, brake in a straight line before the curves, and leave double the following distance behind anything spraying slush.Coastal storms add their own trick: mid-event flips between snow and rain. If the forecast shows temperatures hovering near freezing at pass level, assume the surface will change several times during one drive. Thompson Pass is the extreme case, so carry chains there even with good tires and check whether avalanche control work is scheduled before committing to the climb.The logistics do not change with the pattern. Check 511 before the passes, keep the tank above half through the mountain sections, and carry the winter kit every trip: layers, food and water, shovel, headlamp, jumper cables. Leave the summer habits with the summer tires. This winter is forecast to be warmer, and on Alaska roads that is the opposite of a break.AdvertisementAdvertisementThis story was originally published by Autoblog on Aug 3, 2026, where it first appeared in the News section.
