The Met Office has issued a yellow 'be aware' warning of fog for parts of South East Wales.It says visibility could be down to 100 m in places. This is most likely in low lying areas and river valleys.
There could be delays to bus and train services, plus delays or cancellations to flights.
Network Rail says thousands of rail passengers in Wales and the borders will suffer hours of delays and cancellations in the next month as 'bridge-strikes' - when a lorry that's too big hits a low bridge - reach their peak.
Technology is now being used on Bute Street rail bridge in Cardiff, one of the busiest railway bridges in Wales.
A remote bridge camera system has been installed. The new system will allow engineers to remotely monitor the structure when a strike occurs. This reduces the time it takes to confirm if any significant damage has been caused to the structure and it means trains can get moving again quickly once it has been established the structure is safe.
Network Rail has also been working with haulage companies to urge drivers to measure vehicles and plan their route to avoid bashing bridges as part the 'What the truck' campaign.
Every time a large vehicle strikes a rail bridge, it can cause inconvenience for thousands of passengers in Wales and the borders, as well as potential costs for taxpayers.
We work closely with our partners Arriva Trains Wales to get passengers on the move as quickly and safely as possible when an incident does occur, but we need HGV drivers and their employers to get on board with our initiative and make bridge strikes a thing of the past.
