Met Office issues yellow weather warning for Saturday as heavy rain expected in Wales

The Met Office has issued a yellow weather warning for Wales as persistent, heavy rain is expected this weekend.

The slow-moving area of wet weather is forecast to develop across western parts of England and Wales on Saturday, which could bring flooding, power cuts and travel disruption to locations, including Cardiff and Swansea.

Which areas will see the worst of the rain is still up for debate, but some places could be hit with as many as 60mm, meteorologists say.
