Charleston International Airport canceled all flights Thursday night because of a radar-equipment malfunction and low visibility.

Incoming and outbound flights are not expected to resume until at least noon today.

Airport spokeswoman Becky Beaman said 12 flights so far had been canceled because of the “bizarre fog” and the need to repair the VOR navigation system.

Some incoming flights were diverted to Savannah and Columbia.

Those expecting to depart last night or today “either have been sent home or sent to a hotel,” she said.

Beaman said the airlines are contacting affected travelers. For those expecting to greet someone today, “contact the person’s airline before you come out.”
