Have you heard of the "super fog" in Iowa?

No, "Super Fog" has nothing to do with the 1980 John Carpenter movie or Stephen King's book/movie "The Fog".

However, it can be just as dangerous-but without creatures or ghosts.

According to the National Weather Service, the definition of super fog is:

A mixture of smoke and moisture released from moist smoldering organic materials (such as brushes, leaves, and trees) is mixed with cooler, almost saturated air. Visibility was reduced to less than 10 feet. In breeze conditions, the super fog winds through lowland areas such as river beds or drainage ditches. Super fog can be very dangerous and has become the cause of several large multi-vehicle collisions.

Sounds like something from a movie, right?

At this time of the year, we should pay more attention to "frozen fog."

Freezing fog means that when the surface temperature is equal to or lower than the freezing point, very small water droplets in the fog will immediately freeze on the surface. This includes branches, stairs, sidewalks, roads, and even your vehicle.

The National Weather Service said that freezing fog can cause black ice to form on roads. The definition of black ice: clear ice (not white), with black roads visible below. This situation is most common in the early morning, especially after the melting snow on the road has a chance to freeze again overnight.

When driving in fog, use low beam and/or fog lights. They will help you see farther in the fog. Do not use high beams.
