Dense Fog Advisory Extended In Maryland

MARYLAND — A haze across the region prompted authorities to issue a dense fog advisory Thursday morning, then extend it until noon.

Driving conditions may be hazardous because of the low visibility, the National Weather Service advises. Visibility is less than 0.25 mile.

Drivers should leave extra distance, reduce speed and use headlights, the advisory states.

Most of the state is under the advisory, except southern Maryland, where St. Mary's and Calvert counties are not included.

The dense fog advisory is in effect until 12 p.m. on Thursday, Oct. 22.

Authorities issued a hazardous weather outlook stating that dense fog is also likely overnight Thursday into Friday morning.
