Winter storm watch for the Brooks Range
The National Weather Service has issued a Winter Storm Watch for the central Brooks Range in Alaska, with accumulations between 7 and 13 inches (18–33 cm) expected from Thursday evening through Friday night. The advisory—issued by NWS Fairbanks—covers the area south of Toolik Lake, with a particular focus on Atigun Pass and Anaktuvuk Pass, both of which lie along the Dalton Highway, a vital transportation corridor for the Arctic region.
Timing and snow totals
Snow is forecast to begin late Wednesday, with heaviest snowfall arriving Thursday evening through Friday afternoon. This marks an exceptional meteorological event for early June, a period generally associated with thawing and breakup in most parts of Alaska. Despite being rare, snowstorms in the Brooks Range in June aren’t entirely unprecedented due to the area’s high elevations, which exceed 4,000 feet, and the influence of persistent Arctic air masses.
Travel impacts along Dalton Highway
Conditions are expected to deteriorate rapidly as snowfall intensifies, creating hazardous travel along high-altitude routes. The Dalton Highway, which connects Fairbanks to Deadhorse near the Arctic Ocean, could experience whiteout conditions in the mountain passes, severely affecting logistics, truck transport, and emergency access. The NWS has advised all travelers to prepare for difficult road conditions and to follow weather alerts closely.
Historical context and climate volatility
This early-summer snowfall follows a historically warm and snow-deficient winter for Alaska. During the 2025 Iditarod Trail Sled Dog Race, snow scarcity forced organizers to relocate the ceremonial start from Anchorage to Fairbanks for the fourth time, due to the lack of snowfall near Nikolai and the absence of permafrost, making the trail unsafe for both sled dogs and mushers.
This storm reinforces the climatic unpredictability of interior and northern Alaska, where summer daylight may prevail, yet Arctic air incursions still bring heavy snow well beyond the typical winter season.
Hazard escalation possible
Meteorologists at the National Weather Service have indicated that the Winter Storm Watch could soon be upgraded to a warning, depending on the storm’s evolution. Local authorities, emergency managers, and state transportation departments are actively monitoring the situation, given the logistical significance of the Dalton Highway and the potential for isolated communities to become temporarily cut off.
As the week progresses, all attention remains on Alaska’s northern corridor, where the resurgence of winter weather in June is expected to create both spectacle and challenge across this remote, rugged region.
