The Met Office has issued an 11-hour warning after heavy rain and thunderstorms battered the UK overnight.
The forecaster has put in two yellow warnings for thunderstorms in the south and south west of England, but one of these has been extended due to the adverse weather conditions.
Areas affected include London and nearby cities such as Oxford, Reading, and Slough in the west. In the east, this applies to Soutend-on-Sea, Luton, Essex, Thurrock and parts of Hertfordshire.
In their update, the Met Office said the warning had been extended until 10am because there was still a risk of thunderstorms.
They explained: “Updates to warning area as thunderstorms have now cleared Sussex and most of Kent.
“However, the warning end time has been extended as thunderstorms are expected to continue through the morning before gradually clearing westwards.
“Thunderstorms are expected to move westwards across some parts this morning bringing spells of heavy rain accompanied by frequent lightning with potential for 15 to 25 mm of rain to fall in 1 or 2 hours in a few places. Hail and gusty winds may also affect a few spots.”
