A rare late-August snowstorm is taking aim at the highest road in Alaska today, Thursday August 27, 2026, with the National Weather Service in Fairbanks issuing a Winter Weather Advisory for the central Brooks Range through 4 a.m. Saturday. Up to 6 inches of snow, blowing snow, and wind gusts to 30 mph are expected to batter Atigun Pass and the Dalton Highway, the remote gravel haul road made famous by “Ice Road Truckers,” just as most travelers heading north are still packing for summer.
Peak danger window: overnight tonight through Friday, when blowing snow could drop visibility to half a mile or less near Atigun Pass and an overnight refreeze turns melted snow into invisible black ice on the 4,739-foot crossing.
What to Expect
- Snow totals: Up to 6 inches possible, with the heaviest accumulation near Atigun Pass. Snow is initially expected above 2,500 feet, with snow levels rising toward 4,000 feet on Friday
- Wind and visibility: Gusts up to 30 mph with blowing snow reducing visibility to half a mile or less, most likely above 4,000 feet
- Conditions: Periods of snow, blowing snow, and a wintry mix through early Saturday morning
- Zone affected: Atigun Pass, Anaktuvuk Pass, Galbraith Lake, and the Dalton Highway from Mile Post 232 to Mile Post 322
Because daytime temperatures are hovering near freezing, some of the falling snow will melt on warm pavement during the day, which can make the road look deceptively clear. That is exactly what makes this pattern dangerous. This is now the third alert-level snow event on this same stretch of the Dalton in 2026, after a June winter storm watch for 6 to 12 inches and a late-July advisory that left snow on the ground into the final days of the month. Summer snow in the Brooks Range is not a fluke anymore this year; it is periodic.
Road Conditions
The Dalton Highway is not a road that forgives being caught off guard. It runs 414 miles from just north of Fairbanks to the Prudhoe Bay oil fields, roughly three quarters of it gravel, with no cell service anywhere along its length. Coldfoot, the main waypoint, is the last fuel stop for 239 miles. Condition reports only reach the state’s 511 system after maintenance crews physically drive the road and call them in, so what you see on a webcam may already be hours old.
During this advisory, expect snow-covered and icy stretches, soft and greasy gravel where snow has melted into slush, and sudden whiteouts where blowing snow cuts visibility near the pass. Even where the road looks merely wet, air temperatures at pass elevation slide below freezing after midnight and turn that meltwater into a transparent glaze. Knowing what your drivetrain can and cannot do matters here, and Autoblog’s breakdown of AWD versus 4WD is worth a read, because neither one shortens your stopping distance on ice.
Why Atigun Pass Is So Dangerous
At 4,739 feet, Atigun Pass at Mile Post 244 is the highest year-round-maintained pass in Alaska and the only place a road crosses the Brooks Range. Drivers do not get to reroute. They go over it or they stop and wait. The atmospheric lapse rate means temperatures at the crest can run 15 to 20 degrees colder than Fairbanks on the same day, and the north descent drops at grades as steep as 12 percent, which is a punishing combination when the surface is iced over. The pass has a long history of putting vehicles off the road and drawing full closures when drifting snow gets bad enough, so a posted alert here carries real weight even in what the calendar still calls summer.
Winter Driving Tips
If you have to run the Dalton this week, treat it like a winter crossing even though it is August. Carry chains, winter-rated tires, a blanket, a flashlight, a portable charger, extra food and water, and a full tank of fuel before you leave the last services, because help can be hours away with no way to call for it. Give yourself at least triple the stopping distance you would use on dry pavement, and slow down well before the descent rather than braking on it. If your vehicle is set up for summer and you are suddenly facing winter, Autoblog’s roundup of the best cars and SUVs for snow and winter driving is worth a look, and our best practices for driving in snow, ice, and rain guide covers skid recovery and what to keep in your trunk. Check the Alaska DOT Dalton Highway page and Alaska 511 for the latest closures before you go.
Timing
The advisory runs through 4 a.m. Saturday, with snow, blowing snow, and a wintry mix expected overnight tonight into Friday. Snow levels are forecast to rise toward 4,000 feet on Friday, which will turn lower-elevation snow to rain but keep the heaviest impacts focused on the pass. Even after the advisory expires, the overnight refreeze will keep the pass hazardous into the weekend, so drivers should not assume the road is clear just because the alert has lapsed. We’ll update this article as conditions evolve.
