Late last night, Saturday, the Met Office extended a yellow weather warning for rain put in place for much of the south of the country to cover Greater Manchester and more parts of the north.

The warning, which is in place all day, is in addition to a further such yellow warning in place on Monday, September 23.

The Met Office warns that communities could be cut off by flooded roads and that spray and flooding could lead to difficult driving conditions and road closures.

Power cuts are also possible, according to the weather agency, with the potential for homes and businesses to be flooded, as well as delays or cancellations to train and bus services.

The Met Office says: “Showers and thunderstorms are expected to merge into broader areas of heavy rain across parts of Wales, Central and Southern England during Sunday.

“Whilst the strongest signal for impactful rainfall totals appears to be centred across east Wales and west-central England, there is potential right across this highlighted region for some places to see 40-70 mm in two to three hours, with a chance that a few places could receive 80-100 mm through the course of the day.

“South West England looks likely to see some heavy rain during the early hours of Sunday morning, breaking up into slow-moving, heavy and in places thundery downpours during the day time.

“Meanwhile, the areas of heavy rain are likely to continue pushing north and west, becoming slow moving across some northern and possibly eastern reaches of the warning area during the rest of Sunday.”

According to the Met Office’s “impact matrix”, the weather event – which affects much of England and most of Wales – has a “low likelihood and a medium impact”.

A yellow weather warning is the lowest level of warning issued by the weather agency.

Higher level warnings issued by the agency are amber warnings and the rare red warnings.
