NWS Fairbanks winter storm warning: Could 15 inches of snow bury highways in Alaska? See areas facing hazardous travel conditions

At least 15 inches of snow could fall through Friday as a winter storm warning remains in effect, according to the National Weather Service (NWS). The heaviest snowfall is expected overnight, although some areas could see a changeover to rain before the storm moves out. The NWS Anchorage winter storm warning covers Alaska's Northern Susitna Valley from 1 p.m. Thursday until 2 p.m. Friday AKDT. The affected areas include Chulitna, Broad Pass and the Denali Highway.

Forecasters have issued a particular warning for motorists travelling along the Parks Highway, stating: "Travel could be very difficult, with low visibility and rapidly accumulating snow along the Parks Highway."

The Parks Highway serves as a major route connecting Anchorage and Fairbanks, with the stretch running through Broad Pass falling within the warning area. Snow accumulations of 7 to 15 inches are expected, while visibility could drop to a quarter-mile or less at times.

Alaska winter storm warning

In Alaska, a winter storm warning is bringing heavy snowfall with up to 15 inches of snow forecast in the Northern Susitna Valley. The heavy snow is expected to reduce visibility and hazardous travel conditions to parts of the state. The NWS warned that rapidly accumulating snow could make travel very difficult, especially during periods of heavier snowfall.

NWS Anchorage points drivers to 511.alaska.gov or the 511 phone line for current road conditions, and recommends keeping an extra flashlight, food and water in the vehicle in case of an emergency.

"Highest amounts expected between mile marker 215 and 225 along the Parks Highway. Slow down and use caution while traveling. Visit 511.alaska.gov or call 5 1 1 for the latest road conditions," the NWS advisory read.

Although the 15-inch forecast comes from NWS Anchorage, the National Weather Service Fairbanks office has also issued separate winter weather advisories for parts of Alaska. The NWS has forecast 4-8 inches of snow in southern Denali Borough and around 6-12 inches in eastern Alaska Range south of Trims Camp.

Other Alaska areas under winter weather advisories

The Southern Denali Borough advisory covers Cantwell and part of the Parks Highway, while the Eastern Alaska Range advisory includes the Richardson Highway corridor near Trims Camp. The National Weather Service's Fairbanks office has classified these areas under winter weather advisories rather than the 15-inch winter storm warning issued by its Anchorage office.

Driving conditions could become more difficult if temperatures climb above freezing, causing snowfall to turn wet and heavy. The forecast suggests snow could mix with or change to rain on Friday afternoon, potentially creating additional hazards for motorists.

Drivers are advised to carry emergency supplies, including food, drinking water, a flashlight and warm clothing. Those travelling behind snowplows should maintain a distance of at least 200 feet, as blowing snow can significantly reduce visibility.
