'Super fog': Weather event may have played role in deadly I-95 crashes

A dense fog advisory is in effect for portions of Volusia County until 9:00 a.m. Thursday, after deadly crashes shut down Interstate-95.

The cause is believed to be "super fog," which is a mixture of smoke and moisture in the atmosphere. Visibility is typically lowered to less than 10 feet. FOX 35 is working to confirm if there were prescribed burns in the area adjacent to the interstate.
