Patchy dense fog is being observed in parts of interior Southern Connecticut and within parts of the Lower Hudson Valley and will likely persist until 8am. Motorists should be prepared for rapid changes in visibility while driving in these areas early this morning. Visibilities within the patchy dense fog will be down to a quarter mile or less. If driving this morning, slow down and keep your distance from vehicles in front of you. Make your vehicle is visible to others on the roadway by using your low-beam headlights. Do not use your high-beam headlights (brights) as they could make the visibility worse.
