Patchy Dense Fog Continues For Areas Northwest of I-4... At 850 AM, surface observations, satellite imagery, and traffic cameras showed fog persisting across Lake, Seminole, northwestern Orange, and northwestern Volusia Counties. Visibilities in some areas remain less than a half of a mile. Fog is expected to begin to lift now that the sun has risen. However, patchy dense fog will remain possible through around 10AM. Drivers should prepare to encounter rapid reductions in visibility on their morning commute. Consider leaving early so that you can arrive safely at your destination as a safe driving speed. When driving in dense fog, slow down, use only your low beam headlights, and leave extra distance between your vehicle and the one in front of you.
