The UK is set to be hotter than the Bahamas next week as tropical air pushes temperatures above 30C.
Over the weekend the mercury could hit 25C (77F) in southern England but it will continue to rise into next week.
In a north-south split, southern parts of the country will have a largely fine and dry weekend with long spells of autumn sunshine, while a weather warning has been issued for western Scotland where as much as 150mm of rain could fall in hilly areas.
Areas will be hit by torrential downpours that could bring almost a month’s worth of rain in just one day, with a yellow weather warning in place from 6pm on Saturday to Sunday evening.
Met Office forecaster Bonnie Diamond said the “tropical continental air pushing up from a southerly direction in combination with light winds” will see temperatures of up to 25C on Sunday and then 29C (84F) by Monday.
The top temperatures expected on Tuesday could hit 31C (88F) and remain into Wednesday, but there is the possibility of some thunderstorms mixed in. The Bahamas is expected to see temperatures of 30C on Tuesday.
“It definitely feels like one last blast of summer even though we are, meteorologically speaking, in autumn,” she added.
The September heat follows on from an August heatwave which saw temperatures top out at 34C for six days running last month.
