The Met Office has put in place a yellow thunderstorm warning, which could see parts of southeastern England at risk of flooding, lightning strikes, hail and strong winds.
The warning comes into effect at 1pm on Sunday September 17 and remains until 6am on Monday September 18, and covers the southeastern coast, London, East Anglia and most of Lincolnshire.
In a post shared on X, formerly Twitter, the Met Office explained that these areas could see “severe” storms with the possibility of 30-40mm of rain falling within an hour.
A further warning has already been in effect over southwestern parts of the country since 3am Sunday morning and is due to last until 6pm this evening.
The Met Office has warned that this conditions could impact travel and lead to localised flooding in the affected areas.
A spokesperson from the Met Office told Express.co.uk that they were keeping a “close eye” on developments, with the weather front gradually moving from the west across to the east of England throughout the rest of the day and tonight, before moving northwards.
They warned that showers will be “locally heavy”, with half a month’s worth of rain falling and the possibility of hail in some places.
According to WX Charts the storm will move off over the North Sea at the beginning of next week.
Although the chance of serious disruption is “small”, the Met Office added that homes and other buildings could be damaged by the conditions and that floodwater may start to rise quickly.
There is also a risk that public transport services could be delayed or cancelled and that driving conditions may become difficult due to spray and roadwater.
This severe weather comes after Hurricane Lee hit the northeast coast of the US and eastern Canada, with its aftermath leading to more autumnal weather conditions in the UK next week.
The Met Office said: “Hurricane Lee, which will affect northeast USA and east Canada in the short term, is likely to transition into a regular area of low pressure as it re-emerges into the Atlantic early next week.
“By this stage it will have lost its hurricane characteristics as the sea surface temperatures are not high enough to sustain it, though it is likely to bring a spell of typically autumnal wet and windy weather to the UK mid-week.
“Beyond that the forecast becomes more uncertain, but further periods of wet and at times windy weather seem likely.”
