Met Office warns of torrential downpours and possible floods in Wales

Heavy showers, torrential downpours and thunderstorms may cause travel disruption and some flooding in parts of Wales, the Met Office has warned.

The weather serviced has issued a yellow warning, and says heavy showers already affecting the south and east of the Isle of Wight will become more widespread across the warning area, which includes parts of Wales, through the afternoon, with some thunderstorms also developing.

It added that these may be quite slow-moving and last for an hour or two. Some torrential downpours are possible with a few places seeing 50 mm of rain or more within a few hours. Lightning and hail are also additional hazards, it says.

• There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
• Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
• Spray and sudden flooding could lead to difficult driving conditions and some road closures
• There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost
