The Met Office has issued yellow weather warnings for Tuesday and Wednesday for flooding and “persistent heavy rain” throughout north-west England, much of Wales and south-west Scotland.
Cardiff and Bangor have two yellow weather warnings and another which covers Lancashire and southern Cumbria which will remain until 8pm.
The Met Office has issued a third yellow warning for rain in south-western and central Scotland which also includes Glasgow and there will be “some disruption” in these areas.
There will be “flooding of a few homes and businesses,” with “spray” on the roads and there could be “possible” power cuts.
Met Office meteorologist Alex Deakin said, “The rain will be spreading its way through eastern England and then through Scotland.
“There will be heavy and persistent rain for north-west England and parts of Wales, and, because it has been so wet recently, this extra rain could cause some issues, so we do have Met Office yellow warnings in place.”
He added, “For many it will feel milder than Monday, but there is more wet and windy weather to come through the evening across Wales and western parts of England.
“Rapidly that band of rain should sweep across England and Wales, leaving clearer skies for a time but also plenty of showers coming in.”
