Dense Fog Advisory in Effect for Delmarva Beaches, Visibility Drops to Quarter Mile

Friday, March 13, 2026 at 8:50 AM

Dense fog is reducing visibility to just a quarter mile across Delaware beaches and South Jersey coastal areas, prompting safety warnings for Tuesday morning commuters.

A Dense Fog Advisory remains in effect for Delaware beaches and parts of South Jersey until 10 AM Tuesday morning, creating hazardous driving conditions across the coastal region. The National Weather Service reports visibility has dropped to just one-quarter to one-half mile in dense fog, significantly impacting areas including Delaware’s coastal communities, Cape May County, Atlantic County’s coastal areas, and parts of Monmouth and Ocean Counties in New Jersey. Motorists traveling along Route 1, the coastal highways, and beach approaches should exercise extreme caution during the morning commute. The thick fog is expected to persist through the overnight hours and into early Tuesday morning. If you must drive in these conditions, the National Weather Service strongly advises slowing down, using your headlights, and maintaining extra distance between vehicles. Avoid using high beams, as they can actually reduce visibility in fog. The advisory is scheduled to expire at 10 AM Tuesday, though conditions may begin improving earlier as morning temperatures rise and help lift the fog. Travelers should check current conditions before heading out and consider delaying non-essential trips until visibility improves.
