Train and bus services may face delays and cancellations where flooding or lightning strikes occur.

The National Highways has advised the public to drive safely under the conditions.

It comes after a heat health alert from the UK Health Security Agency and Met Office was extended.

A spokesman for the Met Office said: "Scattered heavy showers and thunderstorms are then expected to develop through Thursday afternoon and evening across parts of central, southern and eastern England, and perhaps also south Wales.

"These have the potential to produce 50 mm or more in one to two hours, along with gusty winds, large hail, and the risk of surface water flooding."
