The South East and eastern England are set to be hit by thunderstorms and heavy rain today as the Met Office issued a yellow warning.
Forecasters said 50mm of rain could fall in some areas over several hours, and driving conditions may be affected by spray, standing water and even hail.
This could mean longer journey times for motorists and bus passengers, and there may also be delays to train services.
Power cuts, flooding and lightning strikes are possible, and some buildings could be damaged.
The warning is in place until 3pm.
On its website, the Met Office wrote: “Outbreaks of heavy, thundery rain are likely to develop and move across east and southeast England from the early hours of Thursday.
“10-20mm of rain is likely over quite a large area but with some embedded thunderstorms some sites are likely to see 30-40mm in two to three hours, and perhaps 50mm or more over six hours.”

It added: “Lightning will be an additional hazard. The area of rain is expected to ease from the southwest before clearing into the North Sea during Thursday afternoon.”
Looking further ahead, Sky’s weather producer Joanna Robinson said that Friday will be largely fine, but there will be more showers around, mainly in the North and West.
She added: “High pressure looks to be in charge over the Bank Holiday weekend, bringing mostly settled conditions.”
Robinson said that Saturday will be mainly fine, but there will be a scattering of showers in the South, while more prolonged rain will affect the far North West.
Sunday will bring fewer showers to the South, but patchy rain will linger across western Scotland and perhaps Northern Ireland too, she went on.
“By Monday, most places look dry, with good spells of sunshine, but a few showers can’t be fully ruled out across the North and West. It’ll be breezy in the North West and along the South coast throughout.”
She also said: “Temperatures will climb through the weekend, especially across England and Wales, perhaps reaching the high twenties on Sunday and Monday in the South. There’ll be chilly nights in some rural parts of Scotland and Northern Ireland, especially on Friday night.”
Forecasters have warned there needs to be a period of above average rainfall to ease the drought, which has been declared across swathes of England.
Millions face hosepipe bans as heatwaves pushed up demand for water, and the ongoing dry weather has led to parched grass and struggling crops, streams drying up, and low river and reservoir levels.

Despite torrential downpours in some places last week which caused flash flooding, the UK as a whole has had only 46% of the average total rainfall for August so far this month, the Met Office said.
Much of the country has seen even drier conditions – with only 35% of the total expected rainfall for the month so far in England, 34% in Wales and 39% in Northern Ireland.
And in southern England, there has been just 29% of the month’s average from 1991 to 2020.
