* WHAT...Rain and freezing rain expected. Ice accumulations around a light glaze. * WHERE...Anchorage, Eagle River, and Lower Matanuska Valley (including Palmer and Wasilla). * WHEN...Until noon AKST today. * IMPACTS...Roads, and especially bridges and overpasses, will likely become slick and hazardous. Travel could be very difficult. The hazardous conditions could impact the Tuesday morning and evening commutes. * ADDITIONAL DETAILS...Light rain, in combination with surface temperatures right around freezing, may lead to a light glaze of icing on already-icy side and neighborhood roads.
Slow down and use caution while traveling. For the latest road conditions call 5 1 1 or visit 511.alaska.gov. Be prepared for slippery roads. Slow down and use caution while driving. If you are going outside, watch your first few steps taken on stairs, sidewalks, and driveways. These surfaces could be icy and slippery, increasing your risk of a fall and injury.
Dense Fog Advisory issued December 2 at 12:07AM AKST until December 2 at 5:00AM AKST by NWS Anchorage AK
Effective: Tue December 2, 2025, 12:07 AM
Expires: Tue December 2, 2025, 5:00 AM
* WHAT...Visibility one-quarter mile in dense fog. * WHERE...Anchorage, with the worst conditions in the Anchorage Bowl. * WHEN...Until 5 AM AKST early this morning. * IMPACTS...Hazardous driving conditions due to low visibility and icy roads. Below freezing temperatures may lead to frost on bridges and roadways. * ADDITIONAL DETAILS...Main roads may be icy as water on surfaces refreeze overnight. Side and neighborhood roads remain icy and will combine with the fog and low visibilities to make travel difficult.
A dense fog advisory means visibilities will frequently be reduced to less than one quarter mile. If driving, slow down, use your headlights, and leave plenty of distance ahead of you.
