Motorists are being urged to take extra care on the roads this morning following a fog warning from the Met Office.
A yellow 'be aware' weather warning has been issued for much of Dorset until 11am today.
Longer journey times and hazardous driving conditions are possible.
There could also be delays to bus and train services, plus delays or cancellations to flights.
The chief forecaster's assessment reads: "Fog has developed overnight across parts of southern England and south east Wales.
"Not everywhere in the warning area will experience fog, though where this does form the visibility will drop below 100 m in places. This is most likely in low lying areas and river valleys."
