THE Met Office has issued a yellow weather warning for northern Britain today as the first of FOUR Atlantic storms sweeps in.
Forecasters say Britain faces an “early Autumn” in the coming weeks due to intense downpours – before a 31C heatwave kicks in later.
The weather warning for thunderstorms is in place until 10pm tonight and covers much of Scotland and northern England.
And the 1,200-mile wide storm system – which is set to last until Wednesday – is just the first in a series to hit.
The North and West will be wettest but all parts will see showers – and the Met Office is forecasting near-40mph gusts in the South.
The second low pressure zone hits from Friday to Sunday, with more squalling rain battering the UK.
A third and fourth low pressure system in the following week were forecast by The Weather Outlook – which predicts dangerous 50mph gusts.
But weather forecasters said the summer “isn’t over” – as more heat is on the way later this month.
The Met Office predicts hotter and drier conditions in the second half of August as thermometers are set to hit 31C.
The Met Office’s contingency forecast shows there is a 60 per cent probability of this month having August’s hottest UK average temperature since 2004’s 16.1C.
Met Office forecaster Mark Wilson said: “There’s potential for high rainfall totals as low pressure dominates the next week across the country. We’re closely monitoring further warnings.
“The first low pressure brings heavy showers until Wednesday, heaviest in the North and West but with gusty winds in the South, and the next low pressure from Friday brings showers for the weekend.
“Unsettled conditions will probably persist until mid-month.
“After August 17 has signs high pressure could build, bringing drier and more settled conditions in the South, with a chance of warmer interludes.”
The Weather Outlook forecaster Brian Gaze said: “It’s an early taste of autumn with four Atlantic low pressure systems spoiling the next fortnight of school holidays.
“Floods and 50mph gusts are expected.
“But summer isn’t over. Heat is forecast to return from mid-August, with 31C in the South as continental warmth returns.”
Ex-BBC and Met Office forecaster John Hammond of weathertrending said: “It’s not good for holidays, with an increasingly wet and windy autumnal spell ahead, with flooding possible.
“But summer fights back after August 18, with a drier and warmer end to August.”
The Met Office said: “For August, above-average temperatures are more likely than below-average.”
