"There still remains some uncertainty in the details for Thursday evening and overnight, but some locations may see up 20mm to 30mm of rain in two to three hours and perhaps 40mm to 60mm in three to six hours.

"Given the recent very wet weather, this will bring the potential for further flooding and transport disruption."

People are urged to be cautious of "spray and sudden flooding" on the roads leading to dangerous driving conditions.

There is a small chance of flooding to homes and businesses and there may also be delays and cancellations to train and bus services and power cuts.
