Patchy and in spots dense fog has lingered from the overnight into this morning throughout the Eastern New York area. Visibility is low in many locations, below one quarter of a mile. It's best to take it slow if you must head out on local roadways and call ahead for flight information as some air travel has been re-routed due to the fog. 

Remember to use your low beams and leave extra space between vehicles.

Fog should thin out a bit, improving by mid- to late morning.
