Hurricane Humberto is heading directly for the UK, with the remnants of the storm expected to bring heavy rain and strong winds, according to the Met Office .
The ex-tropical storm is due to make landfall in Britain next week, marking an end to the summer weather .
Temperatures should reach 25C on Saturday on what will be the final day of a mini-heatwave across the UK.
But the country will get a soaking on Sunday as temperatures start to drop and conditions will finally begin to feel more Autumnal.
Simon Partridge, a Met Office forecaster, told Mirror Online: "The remnants of Hurricane Humberto are expected to arrive across the UK on late Monday.
"It will bring some outbreaks of rain and some stronger winds. There's potential for some strong winds and maybe a few gales around western coasts.
"Next week will feel more Autumnal than this week and will be a more unsettled affair."
Hurricane Humberto cleared Bermuda overnight and is now moving to the north of the islands.
It is due to move across the Atlantic over the next few days.
Temperatures will drop down to highs of 19C on Monday, the Met Office says.
However, there will still be a few days of warm sunshine before the rain kicks in.
Today promises bright and balmy 21C weather, with highs rising to 22C tomorrow and 25C on Saturday, Weather Online predicts.
Things will take a turn on Sunday as rainfall spreads across the country and temperatures dip down to 22C.
Hurricane Humberto knocked out power lines in Bermuda on Wednesday night, plunging the islands into darkness.
The storm whipped the British territory with powerful winds and heavy rain.
Even as Hurricane Humberto was moving away, Miami-based U.S. National Hurricane Center forecast a prolonged period of dangerous winds through Thursday and warned that dangerous breaking waves could lead to coastal flooding overnight.
More than 28,000 homes and businesses had lost electricity by early evening, according to electricity company Belco.
Flights were canceled and some residents in the capital, Hamilton, covered windows with wooden planks and metal sheeting.
