Storm maps show UK almost 'disappear' under huge 630-mile rain bomb - 9 wettest cities

New weather maps have revealed a huge storm and rain bomb is set to craash into the UK in a matter of days. Maps generated by WXCharts show a huge band of heavy rain - extending some 630 miles from the Hebrides in Scotland to southeast England - descending on Sunday (September 14).

Barely any parts of the UK look set to escape the downpours, with several major cities across the country to be hit the hardest. In England, the rain is predicted to hit around 9am on Sunday, drenching the major cities of Manchester, Newcastle, Birmingham, Southampton, Plymouth and London. Near Manchester, as much as 5mm/hr of rain is expected to fall, while in Newcastle, around 2.5mm/hr is predicted. Wales will also not escape the downpour, with up to 1mm/hr predicted in the nation's capital, Cardiff.

Further north in Scotland, only parts of the Highlands will escape the downpour in the early hours, though WXCharts weather maps generated for later in the day suggest the rain will sweep northwest by midday on Sunday.

The weather maps predict Edinburgh will see the heaviest rain, with as much as 5mm/hr of rain expected.

Across the Irish Sea in Northern Ireland, where the rain will strike first, it is Belfast that will see the heaviest showers. Here, around 1mm/hr of rain is expected.

Paul Gundersen, Chief Meteorologist at the Met Office, said: "We have been monitoring a deepening area of low-pressure over the North Atlantic that might bring impactful weather to the UK, most likely on Sunday and Monday. At present, a named storm is unlikely."

The Met Office's weather forecast for Friday until Sunday says: "Remaining changeable with sunny spells and blustery showers, these frequent and occasionally heavy with a risk of hail and thunder. More persistent rain likely arriving on Sunday. Feeling cool."
