Dangerous, Unusually Dense Fog Gives Way to Rain

Conditions are improving Thursday morning, but you might still see some patches of thick fog

A dangerous, dense fog moved into our area after Wednesday night, dropping visibility to a quarter-mile or even zero at times. However, the foggy conditions improved as Thursday morning went on.

The National Weather Service issued a Dense Fog Advisory for most of our area, stretching from Delaware, through Southeast Pennsylvania and into much of New Jersey. The advisory lasts from 8 p.m. until 1 p.m. Thursday.

An earlier NBC10 First Alert for foggy travel conditions has ended.

If you must drive, slow down, use headlights and leave plenty of space ahead of you.

The dense fog could come in waves, so be careful even if it doesn't seem as bad when you head out.

The best advice: plan on giving yourself extra time to go where you need to Thursday morning.

Rain moved in as Thursday morning went on, breaking up the fog, but leading to the potential for slick spots.

The rain is expected to last into Friday before a cold blast this weekend.
