Special Weather Statement issued January 6 at 9:19PM AKST by NWS Anchorage AK

Effective: Tue January 6, 2026, 9:19 PM
Expires: Thu January 8, 2026, 6:00 AM

* WHAT...Dangerous avalanche conditions exist in the backcountry. Human triggered avalanches are likely. * WHERE...For Southwestern Chugach State Park from South Fork of Eagle River to Indian Creek including Upper Rabbit Creek, Glen Alps Recreation Area, and the backcountry terrain near Arctic Valley. This bulletin does not apply to operating ski areas. * WHEN...In effect from Wednesday 6:00 am to Thursday 6:00 am AKST. * IMPACTS... Large human-triggered avalanches are likely. Despite the calmer weather, the snowpack is very unstable and dangerous avalanches can be easily triggered by people. It is likely avalanches may be triggered remotely from flat terrain below steeper slopes. * PRECAUTIONARY / PREPAREDNESS ACTIONS... If deciding to recreate in the backcountry, choose terrain that is flat or less than 30 degrees in steepness, with nothing steeper above you. Cautious route-finding and conservative decision-making skills will be necessary to identify and avoid slopes that could avalanche. Similar avalanche danger may exist at locations outside the coverage area of this or any avalanche center. For more information visit www.ChugachAvalanche.org.

Winter Storm Warning issued January 6 at 4:40PM AKST until January 7 at 12:00PM AKST by NWS Anchorage AK

Effective: Tue January 6, 2026, 4:40 PM
Expires: Wed January 7, 2026, 6:00 AM

* WHAT...Heavy snow and localized areas of drifting and blowing snow across N and W Anchorage. Additional snow accumulations between 1 and 3 inches for lower elevations and locally higher amounts on the Hillside areas. Visibility reduced to one half mile at times during heavy snow. * WHERE...All elevations of Anchorage and Eagle River, Lower Matanuska Valley, Southern Susitna Valley, and Central Susitna Valley. * WHEN...Until noon AKST Wednesday. * IMPACTS...The light and powdery nature of the snow will be easily lofted by winds and vehicles, leading to significantly reduced visibility at times on area roadways. The hazardous conditions could impact the Tuesday evening commute. * ADDITIONAL DETAILS...Bands of light to moderate snow will be possible through Tuesday evening before tapering off from west to east as a drier northwest wind develops. Pockets of light snow will likely linger across the western foothills of the Talkeetna Mountains and over the Hillsides of Anchorage and Eagle River into the overnight hours.

A Winter Storm Warning for snow means severe winter weather conditions will make travel very hazardous. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency. For the latest road conditions call 5 1 1 or visit 511.alaska.gov.

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.
