Dense Fog Seen Throughout Maryland

BALTIMORE (WJZ) -- A large amount of low-level moisture has caused patchy dense fog across central Maryland.

The worst conditions are occurring in northern Maryland near the Mason-Dixon line. In some areas, visibility is below a quarter of a mile.

Use extra caution when driving and allow extra time to get to your destination. You should also only use low-beam headlights.

The National Weather Service says a dense fog advisory may be issued Monday night.
