It's that time of year to be prepared for winter driving conditions, especially this week as a storm spreads snow across the Interior and rain across Southcentral through Thursday. 

Here's a break down of the warnings and advisories in effect because of the snow.

Winter Storm Warning: Now - 6 p.m. Wednesday

Heavy snow will continue for the Western Brooks Range North of Noatak to Kiana where another 3-7 inches of snow is expected, along with up to an inch in the valley areas. 

The Brooks Range north of Ambler to Shungnak will likely see an additional 2 inches of snow and a significant reduction in visibility. 

The Yukon Flats and surrounding uplands including the Steese Highway and Eagle Summit will see an additional 2-4 inches of snow. The heaviest snow accumulations will be in the White Mountains. Up to an inch is expected for much of the Yukon Flats, in addition to poor visibility. 

Winter Weather Advisory: Now - 6 p.m. Wednesday

The Upper Koyukuk Valley will see an additional 1-3 inches of snow with up to 5 inches through Wednesday night. The heaviest snow will be from Prospect Creek north along the Dalton Highway and north of the Koyukuk River. 

The Central Interior will see another 2-5 inches of snow with the heaviest accumulations north of the Tanana River and along the Elliott Highway. Valley areas will see up to an additional inch. 

The Middle Tanana Valley, including Fairbanks and surrounding uplands, will see an additional 2-4 inches of snow. The heaviest snow will be above 2,000 feet. Valley areas east of Fairbanks will see up to an inch. 

The Eastern Alaska Range will see 3-6 inches of snow with up to 10 inches in localized areas. Visibility will also be poor as winds gust to 60 mph near the passes.


While locations north of Talkeetna will see snow, further south most areas will see moderate to heavy rainfall. This storm will deliver half an inch to 2 inches of rain to much of Southcentral, with the highest amounts being across Prince William Sound.

Temperatures will stay warm initially with lows near 40° and highs near 50°, but colder air will filter in late Thursday. Temperatures will fall to the low 30s early Friday. Any lingering showers late Thursday into Friday will likely fall as a snow/rain mix for the lower elevations of Southcentral, especially near Anchorage and into the Mat-Su. 


Chilly nights are also likely Saturday and Sunday with lows dropping to the mid to upper 20s, but by then we'll be back to clear and dry conditions which continue through early next week. 

Drive safe if you're traveling in the snow or rain this week!
