The remnants of Hurricane Epsilon are sending an ominous weather front into Britain as 50mph gales and torrential rain ravage the country.
The rampant cyclone has passed the eastern coast of America and is currently contained in a very deep area of low pressure out on the Atlantic, sending a frontal system towards the UK.
Substantial rainfall will hit the country from Thursday until the weekend, with up to 130mm of rain predicted in the Welsh mountains, and averages of 30-40mm for the rest of the UK.
A yellow weather warning for severe rain has been placed by the Met Office across parts of the west of England from midday Thursday to midnight on Saturday - with flooding and travel disruption a possibility.
In the meantime, heavy showers will strike in southwest England this afternoon, with strong winds along the south coast.
As a result, the Environment Agency has put two flood alerts in place, around the River Thame and Chalgrove Brook.
And by tomorrow the lingering low pressure will result in "lots of showers piling into northern and western areas", according to BBC meteorologist Stav Danaos.
Some of these downpours will be heavy, "with some hail and thunder" and temperatures could plummet as low as 10C due to the chilly wind, he added.
Another frontal system is moving in on Thursday "to bring another bout of wet and windy weather - could turn very wet across northwest England and Wales, with a risk of minor flooding", said Mr Danaos.
However, as the week goes on, temperatures will turn milder and London could see 18C on Friday, according to weather charts.
Though parts of the country could see gusts of close to 50mph as we head into the weekend.
The combination of sunshine with blustery showers for the first half of the week could lead to "plenty of rainbows", according to Met Office spokesman Oli Claydon.
