Hurricanes from the Atlantic are set to Deliver Torrential Rain Across the UK
The UK faces a soggy spell this week as remnants of two Atlantic storms approach, threatening heavy rain and gusty winds.
Foretellers advise that the corridor of the country could see nearly the bottom of the rain over just many days.
The Met Office has issued a 37-hour heavy rain warning for western Scotland, starting 5 pm on Wednesday and running through to 6 am on Friday.
Areas currently under alert include Argyll, Ayrshire, Dunbartonshire, and Renfrewshire.
Officials say the warning could expand as Hurricane Humberto and Hurricane Imelda edge closer, after causing disruption in the US.
“Ten inches of rain not out of the question over the highest ground in western Scotland in the next few days… pretty incredible rainfall totals,” wrote Marco Petagna, senior operational meteorologist at the Met Office, on social media platform X (formerly Twitter).
Deputy chief meteorologist Chris Bulmer added: “Persistent rain will develop from Wednesday, with the heaviest downpours over the hills. Pulses of heavier rain will extend more widely at times. Later in the week, the picture becomes more complex as the storms move across the Atlantic.”

He cautioned: “If this materialises, we could see some very strong winds as well as further heavy rainfall Friday into Saturday, but at this time the development and track of this system remains uncertain. We’re monitoring this closely.”
The Met Office noted that further warnings might be issued later in the week as forecasts become more certain.
For the first half of the week, conditions will be divided. Northern Ireland, western Scotland, and northwest England are likely to face the wettest rainfall. Meanwhile, southern and eastern areas can anticipate drier conditions, with occasional sun and temperatures exceeding 20 °C.

From Thursday into Friday, both wind and rain are prognosticated to spread more extensively as the Atlantic storms exert less influence on the UK.
Presently, Imelda is a tropical storm but was expected to strengthen into a hurricane by Tuesday. Humberto, downgraded from Category 5 to order 3, remains near Bermuda with maximum sustained winds of 115mph.
Although neither system meets UK criteria for official naming, they could combine to create the first significant autumn storm this weekend.
UK Weather Forecast (Met Office)
Today: Cloudy and breezy in the north. Heavy rain clearing eastwards, but further showers anticipated in western Scotland. Away, dry with sunny spells.
Thursday to Saturday: Heavy rain continues in the northwest on Thursday; drier in the south. By the weekend, wet and windy conditions are anticipated nationwide, with fits probably in the north.
Residents are advised to prepare for a potentially turbulent end to the week, with a blend of heavy rain, breezy winds, and changing rainfall conditions.
