Ice fog develops when temperatures are low and humidity is high. Commonly, fog is seen late at night or early in the morning. There are different types of fog that drivers in interior Alaska face.
Basics
Fog forms when the sun rise causes the air and ground to warm up. The change in temperature paired with humidity causes water vapor to condense. During the condensation process, tiny water droplets form and hang in the air. Fog can be seen because of the tiny water droplets. As the temperature rises, the water droplets dissipate and return to their gaseous form. Different weather temperatures cause different types of fog.
Ice Fog
The interior of Alaska often deals with ice fog. When temperatures are very low, water droplets in fog are very cold. In some cases, water droplets freeze and cause freezing fog. However, in some cases, water droplets do not freeze until they touch a surface. Ice fog is made of tiny ice crystals in the air still in liquid form. Drivers must be extra cautious in ice fog conditions because ice crystals can stick to a vehicle or road easily. When the crystals touch a surface, they become ice.
Driving In Fog
If you find yourself driving in foggy conditions, slow down and ensure to use your headlights. If your vehicle has fog lights, use them. Some drivers think high beams are better for foggy conditions, but high beams can reduce visibility. Further, allow yourself extra time to travel in foggy conditions and be patient. If ice fog is on the weather radar, try to stay home when possible and avoiding driving. In cases where staying home is not an option, be extra cautious.
