FAIRBANKS - Fairbanks and low-lying areas in Interior Alaska are under a dense ice fog advisory through Tuesday morning, according to the National Weather Service.
Ice fog forms in polluted areas during extreme cold and can reduce visibility from a quarter mile to zero in some areas. The lowest visibilities are forecast for overnight and early Tuesday morning, when temperatures are expected to fall to minus 50 degrees in some areas.
Drivers are urged to keep their headlights on at all times and drive cautiously.
The same areas are also under an air quality advisory for pollution levels that exceed EPA limits for fine particulate pollution. Air quality is at unhealthy levels in North Pole and Fairbanks.
The air quality advisory is in effect through Wednesday.
