Met Office weather warning: Britons face floods and travel chaos as 24hr downpour imminent

The conditions will affect the following areas of South East England: Brighton and Hove, East Sussex, Kent and West Sussex.

According to the meteorologists, a slow-moving rainband is expected to stay close to southeast England through Friday and well into Saturday.

Some heavy rain seems likely, with the possibility of 30 – 40 mm falling in 2 to 3 hours in a few locations, and maybe over 70 mm overall – but still a fair chance that the heaviest of the rain might stay just offshore.

The heaviest rainfall looks like moving away, or at least easing, beyond midday Saturday.
