"The area of rain could then become slow moving, heavy and persistent, especially over north facing hills, before clearing during Thursday morning.

"There is a lot of uncertainty over exactly where the heaviest rain will occur and this warning is likely to be updated. Many places will see 30-40 mm of rain, while a few areas may receive 60-80 mm. There is also a small chance that a few upland areas could see much higher totals, in the order of 100-150 mm."

Today's weather warning comes after a yellow alert for thunderstorms was issued yesterday (Tuesday). It lasted nine hours, covering parts of North Wales.

Deputy Chief Meteorologist Dan Rudman said: “Low pressure is going to influence our weather from the middle of this week, bringing some heavy rain to parts of the UK. Eastern areas are most likely to see the highest rainfall accumulations, though this will depend on the precise positioning of the low pressure.

"It is important to keep an eye on the forecast as the detail becomes clearer, and it is possible Severe Weather Warnings will also be issued.”
