Special Weather Statement issued November 5 at 3:51PM AKST by NWS Anchorage AK

Effective: Wed November 5, 2025, 3:51 PM
Expires: Thu November 6, 2025, 4:00 AM

Snowfall is expected to increase across Turnagain Pass beginning early Thursday morning, with snow levels reaching ground level. Temperatures dropping to the low 20s overnight will likely allow for cold enough ground temperatures to allow for potential accumulations along portions of the Seward Highway. Temperatures in the morning before the snow moves in, may also allow for ice to develop on areas of the roadways, causing slippery road conditions. Snowfall rates are expected to peak into the mid-to- late afternoon, which may further impact travel conditions along this section of the highway. Snowfall rates are expected to decline late Thursday night, ending by late Friday morning.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
