A dense, dangerous fog will move into our area after 8 p.m. Wednesday, sometimes reducing visibility to a quarter of a mile or even zero.
The National Weather Service has issued a Dense Fog Notice for most of our area, stretching from Delaware, through southeastern Pennsylvania, and into much of New Jersey. Counseling runs from 8 p.m. to 11 a.m. Thursday. NBC10 also issued its First Warning about very poor travel conditions.
The fog is likely to move into the Jersey Shore and Delaware beaches first, then move inland.
If you must drive during this time, slow down, use your headlights, and leave plenty of room ahead.
