Weather alert: The UK issued an 11-hour yellow thunder warning that could pose a potential threat

The UK faced a rather wet summer this year but was able to make the most of the last of the summer sun after the month of September started with an unseasonal heatwave. For some parts of the UK, it may start to feel like autumn soon as thunderstorms are set to hit.

The Met Office has issued a yellow weather warning for thunderstorms and has warned that a month’s worth of rain could fall in certain parts of the country.

A yellow weather warning for the southwest

As reported by The Independent, major cities including Bristol, Cardiff and Swansea are under a yellow weather alert as thunderstorms are set to hit the southwest of the UK. According to forecasters, there is a ‘small risk’ that homes and businesses could be damaged due to quick flooding, caused by the ‘torrential downpours’.

The southwest of England and the south of Wales could see up to 70mm of rain to fall within a few hours. The average rainfall for the month of September is 92.45mm.

There could also be a small risk that buildings could be damaged by lightning, hail or strong winds as well as floodwater. The Met Office also warned that there could be a ‘small chance’ of power cuts for some homes and businesses due to potential floodwater.

Met Office meteorologist Rachel Ayers said:

The heaviest and most persistent rain will be tomorrow morning, bringing a risk of some potential flooding in homes and businesses.
