The Met Office has issued a yellow weather warning for much of the South East and London for today, May 21.

The warning comes amid suggestion that "heavy rain and thunderstorms may lead to some disruption."

The Met Office added that there could be disruption to travel throughout the day with spray and sudden flooding leading to difficult driving conditions and some road closures.

Plus, flooding or lightning strikes could see a chance of delays and some cancellations to train and bus services.

The yellow warning for thunderstorms is in place from 12pm today, until midnight today.

Met Office issues weather warning for thunderstorms across London

As well as warnings that travel could be disrupted, the Met Office has shared that there is a "slight chance" of power cuts that could impact services to some homes and businesses.

Sharing details of the warning, the Met Office said: "Whilst some places may remain mostly dry, areas of heavy rain and some thunderstorms are expected to develop from around mid-morning.

"In the south of this warning area, the focus is likely to be slow-moving heavy showers and thunderstorms, perhaps with hail and lightning, which should gradually ease away later on Tuesday evening.

"Meanwhile, further north in the warning area, early showers are likely to merge into more general rain, this heavy and thundery at times, and will persist onwards into Wednesday (which is covered by a separate warning).

"Across the warning area, 20-30mm in 1 hour or less is possible (but perhaps most likely to the south of London), with a few places perhaps receiving 40-50mm in 2-3 hours."

London residents are being encouraged to be safe when out and about and to be prepared for travel disruptions.
