It has also warned of a small chance of delays and some cancellations to train and bus services due to lightning strikes and flooding, as well as possible power cuts, difficult driving conditions, and road closures.
The warning has been issued for the morning after initially being thought that thunderstorms could strike on Saturday evening, during the BBC’s Platinum Party at the Palace.
