Fresh heavy rain warning issued amid hundreds of flood alerts

The Met Office has issued a fresh weather warning for heavy rain, with more than 200 flood alerts still in place.

The new yellow warning is for large parts of southern England and South Wales, and lasts from 12pm on Monday to midnight. Up to 30mm of rain is predicted to fall in some places.

Affected areas include Hampshire, the Isle of Wight, Portsmouth, Southampton and West Sussex.

In southwest England, areas include Cornwall, Devon, and Dorset, with Cardiff, Swansea and Newport among affected areas in Wales.

The Met Office said: "Bands of rain and heavy showers will move east across southern parts of England and Wales during Monday afternoon and evening."

It added: "10-15mm of rain is likely fairly widely with 20-30mm in some places exposed to the strong south to southeasterly winds."

The warning forecasts spray and flooding on roads "probably making journey times longer".

Bus and train services will probably be impacted with flooding of a few homes and businesses possible, it added.

There will also be a chance of some interruption to power supplies and other services, it continued.

Meanwhile, the Environment Agency has 89 flood warnings in place, mostly across southwest England and the East and West Midlands.

There are also 218 flood alerts. A flood warning means flooding is expected, and an alert means flooding is possible.

The Met Office said on Thursday that rain had fallen every day of 2026 so far in southwest England and South Wales.

There has been 50% more rainfall than usual in both, the forecaster added.

Both have experienced a far wetter than average January.

Sarah Cook, flood duty manager at the Environment Agency, said: "Our thoughts are with all those affected by the ongoing impacts of Storm Chandra, including those whose homes and businesses have sadly been flooded.

"Significant ongoing groundwater flooding impacts remain probable in parts of Dorset and Wiltshire, with minor impacts probable for parts of Hampshire for the next five days, and West Sussex from Saturday.

"Environment Agency teams are out on the ground, to reduce the impact of flooding and support those communities affected. We urge people not to drive through flood water - it is often deeper than it looks and just 30cm of flowing water is enough to float your car."
