How quickly can fog form? I-75 in FL
Posted 01 February 2012 - 17:08
Now Highway Patrol is stating that visibility was clear at 3:30 when they opened the highway. Is it possible for fog to form and become that thick within 15 minutes so as to cause this accidents or is it likely highway patrol misjudged the visibility when they opened the road?

Alternatively, a different kind of air could have been intruding and could have raised the level at which this action was occurring, again increasing visibility at road level?
We had a similar incident to this last Nov in SW England, a fireworks display and bonfire near to a motorway caused a dense bank of smog in already patchy fog conditions. Witnesses described a wall of white/black fog that they couldn't see through until they crashed. It was still foggy for sometime afterwards while the rescue and recovery effort was underway, but at the time of the incident a witness about 10 metres lower than the motorway said it was fairly clear.
