A yellow weather warning has been issued for fog, which is expected to blanket much of the UK this evening and could cause travel chaos.

The Met Office said the fog could freeze in some places, covering most of England and the eastern edge of Wales.

Temperatures are set to drop to near 0C overnight for many areas, which could lead to icy roads.

Patchy #fog will form through this evening, with some dense and freezing patches of fog likely overnight, especially across parts of England and Wales 🌫️

The warning is in place from 7pm on Monday until midday on Tuesday, extending from the south of Scarborough to east of Manchester in the North, and east of Exeter in the South.

The fog is “likely to cause slower travel and possible disruption”, the Met Office said.

Buses and trains could be delayed, while flights could even be cancelled.

Drivers should expect hazardous conditions and slower journeys, according to the Met Office.

“The fog is going to be most widespread in southern, eastern England, into the Midlands and the east side of Wales too,” he said.
