THE UK has been engulfed in a major heatwave which is bringing the threat of rolling thunderstorms. So which areas are under Met Office warning?
The Met Office has warned that scattered thunderstorms could lead to some power cuts and travel delays. Almost the whole of the UK is under a yellow alert, proving how unpredictable this weather pattern is. These conditions come as the UK is expected to smash records for the hottest day on record on Thursday.
The yellow thunderstorm warnings began on Wednesday night, and lighting strikes were reported across the UK.
The Met Office warned of a small chance of damage to property from lightning strikes, as well as a slight chance that power cuts could occur.
Today’s warnings expire at 9am, but hazardous conditions won’t cease then.
Heatwave thresholds are expected to be met across wide parts of the country with high temperatures persisting.
Public Health England has issued a heatwave warning, and is advising citizens to drink plenty of fluids, avoid excess alcohol and open windows when it feels cooler outside.
By Thursday temperatures are expected to peak with 38C possible in south east England but 35C (95F) possible as far north and west as Manchester and Birmingham.
Met Office Chief Meteorologist Frank Saunders said: “There is a real possibility of records being broken this week, not only for July but also all-time records.
“The weather setup is broadly similar to the pattern that brought high temperatures to much of continental Europe at the end of June.
“The difference this time is that the wind flow will be more directly from France, paving the way for some exceptional, perhaps record-breaking temperatures.
“As well as high temperatures during the day, overnight temperatures will also be notably warm and could also break records.
“Conditions will feel much more comfortable for western parts of the UK by the time we get to Friday.”
Forecasters have said there is a 60 percent chance the UK could see its hottest-ever July day this week.
If temperatures reach the 38C mark, it would smash the current July record of 36.7C (98.1F), set at Heathrow airport in 2015.
Forecasters also believe there is a 30 percent chance Thursday’s heat could surpass the UK’s all-time record of 38.5C (101.3F), which was set in Faversham in August 2003.
Those in affected areas are being urged to stay out of the sun, drink plenty of water and check on older people who are living alone.
These conditions are the result of a hot air being drawn up from Europe by the jet stream.
