A Meteo Group forecaster added: ‘An area of prolonged rain is moving up over the eastern region and it’s not going to shift until Wednesday night.

‘The rain is not exclusive to the east region but that’s where the persistent and largest rainfall totals of between 50 and 70mm will be.

‘Pretty much the whole of Great Britain will see rain at some point over the next 48 hours.

‘This means there could be some localised flooding.’
