Cornwall is in the midst of a yellow weather warning as heavy rainfall batters the county this afternoon.

The Met Office introduced the warning for rain at lunchtime today and is expecting it to stay in place until 7pm this evening.

Cornwall and the rest of the south west is affected by a yellow warning, while London has been issued with an amber warning.

A Met Office spokesperson said flooding was possible, leading to some transport disruption over parts of the south west this afternoon and evening.

They added: "Heavy and slow moving showers have formed over south west England and south Wales.

"These are generating some large rainfall totals with 15-20mm in an hour and 30mm in two to three hours.

"The showers should start moving more quickly later this afternoon but some impacts may persist into the busy travel period."

People have been warned to watch out for spray and flooding on roads, which could make journey times longer, and there is risk of flooding to low-lying homes and businesses, or some interruption to power supplies and other services.

The forecast shows the heaviest rain moving away from the region over the course of this evening.
