Area fog causes all Monday night departures from Charleston airport to be cancelled

As of about 9 p.m. Monday night, all flight departures from Charleston International Airport were cancelled due to heavy fog in the Lowcountry, according to airport officials.

There were also some early morning flight cancellations and some flight delays, though it wasn't immediately clear if those cancellations were also due to the fog, according to airport spokeswoman Charlene Gunnells.

She suggested residents with flight plans to work with their airlines to make new flight arrangements.

Delta Airlines spokesman Michael Thomas confirmed that they had one cancelled flight to Charleston from LaGuardia Airport, a couple from Atlanta to Charleston and a couple flights delayed in Charleston to the early morning.

"When the fog rolls in like it has in the southwest, it affects visibility," he said. "You have to be able to see the runway to fly an airplane."

National Weather Service meteorologist Blair Holloway said dense fog began rolling in around sunset. Visibility at the airport at 9:30 p.m. was at a half mile, he said.

He added that low visibility from fog would likely hang around overnight and that there was a dense fog advisory until 10 a.m.

The Charleston Harbor also closed at 6:30 p.m. to traffic due to the fog, according to Holloway.
