The Met Office has warned that more freezing fog is expected to form overnight, making driving conditions dangerous again.
The fog is expected to start in the southwest, but move along the south coast through the night and into the morning.
The yellow be aware warning says: “Areas of freezing fog, some dense, are expected to form again during Monday night and into Tuesday morning. The fog will become widespread in places, most likely in the southwest of the warning area early in the night and then in other areas later in the night and early on Tuesday morning.
“Driving conditions will be difficult with journeys likely to take longer than usual and delays to air travel are possible.
“Areas of freezing fog will quickly re-form on Monday evening and night. The fog will form initially, and will probably be most widespread, across parts of the southwest of England, southeast Wales and the southwest Midlands.
“Fog will also form elsewhere but areas of cloud are leading to uncertainty in the timing and extent of the fog and will result in the fog waxing and waning through the night and during Tuesday morning.
“However it is likely that some dense fog patches will develop in other parts of the warning area by Tuesday morning.
“The fog is expected to slowly thin and lift during Tuesday although it may persist in some areas throughout the day.”
