Met Office extends weather warning for heavy rain across Wales

The Met Office has extended a weather warning for heavy rain across Wales.

Forecasters say the country will be hit by torrential showers for much of Wednesday, February 19 just days after storm Dennis left a trail of destruction.

The weather warning was previously due to come into effect from 6pm, but will now be in place from 3pm .

Parts of south Wales could see up to 60mm of rainfall in just 24 hours.

The warning has also been expanded slightly across the north west of Wales.

Rain is likely to be heavy, especially over high ground, during Wednesday and Thursday which may lead to some flooding and travel disruption.

Homes and businesses could be flooded and some communities could be cut off. Spray and flooding could also cause difficult driving conditions and delays to public transport are possible. You can follow live updates here.

An Atlantic weather system arriving on Wednesday is behind the further rainfall, and due to the already saturated ground the chance of further flooding is possible.
