What is super fog? Generally, fog is formed by air moving over a ground of colder temperature, which causes water vapor in the air to condense into tiny liquid droplets. Super fog is caused by this condensed water vapor combining with a mixture of smoke and moisture released from damp smoldering organic material such as brush, leaves and trees. When super fog is formed, visibility is drastically reduced, often to no more than a few feet. http://www.nws.noaa.gov/om/fog/super.shtml #FogScience

If fog reduces your visibility while driving, do not change lanes or pass other vehicles unless absolutely necessary. Be sure that you can stop within the distance that you can see. http://www.nws.noaa.gov/om/fog/ #FogSafety #WinterSafety

Do you know how valley fog is created? First, air at higher elevations cools down, which then drains downslope into the valley. From there, a cool, stable layer forms near the ground, which limits turbulent mixing and traps the cool, moist air. Finally, the air near the ground continues to cool until water vapor molecules are changed into small droplets of liquid water. http://www.nws.noaa.gov/om/fog/mountain_valley.shtml #FogScience

Fog reduces visibilities and contributes to numerous motorist accidents every year. Dense Fog Advisories are issued when visibility drops to or is expected to drop to one quarter mile or less. Take caution and check to see if there are any Dense Fog Advisories issued for your commute before driving. Learn more about #FogSafety by visiting weather.gov/fog. #WinterSafety

Slowing down is the most important thing you can do to drive safely in dense fog. Reduced visibilities can lead to motor vehicle accidents. Visibility is usually the lowest on bridges and near bodies of water. Learn more about #FogSafety by visiting weather.gov/fog. #FogSafety #WinterSafety

Driving in fog can be dangerous. Be on the lookout for sudden changes in visibility. The patchy nature of fog can lower visibility quickly especially if you are driving fast, so be sure to slow down. Visibility may also be lower near rivers. http://www.nws.noaa.gov/om/fog/ #FogSafety #WinterSafety

Fog forms when water droplets are present in the air near the earth's surface. There are several different types of fog—radiation fog, advection fog, freezing fog and others—but all can be hazardous to drivers, boaters or aviators.

If you're a boater, chances are you’ve at least occasionally encountered reduced visibility in fog, and you will need to know how to navigate through it safely. Visibility can be reduced to a just few feet, disorienting boaters. http://www.nws.noaa.gov/om/fog/ #FogSafety #WinterSafety

Dense fog reduces visibilities to a quarter mile or less, which could result in motor vehicle accidents. Here’s what you can do if your vehicle breaks down in dense fog. Move your disabled vehicle to the shoulder of the road, only keep the hazard lights on, and if possible, walk away from the road. Learn more about #FogSafety by visiting weather.gov/fog.
