Weather map shows 938-mile long storm set to hit the UK as Met Office warns of heavy rain

A brutal 938-mile-long storm is set to hit the UK, with nearly 20mm of rain expected to batter some areas in just three hours, according to an incredible weather map. The map, issued by forecasters at Ventusky, shows the majority of the UK covered in either a red, orange, green or blue hue, indicating the severity of the storm which is expected to see wind gusts top 50mph.

The band of low pressure, due on Tuesday September 24, stretches from around the Faroe Islands in the north to Brest in France in the south - approximately 938 miles.

The forecast suggests that it'll be wet everywhere, except for East Anglia and a slither of Southeast England. North Wales, particularly across Eryi National Park (Snowdonia), will experience the heaviest rainfall, with around 18 to 19mm feared to lash down in just a few hours.

Forecasters also predict around 15mm of rain will fall in the same timeframe across Perth and Kinross and Aberdeenshire.

Adding to the hazardous conditions, fog and mist will combine with the rain across northern England, posing a particular risk for motorists during morning rush hour. The maps indicate the thickest of the fog will be across Cumbria, including the Lake District, where again around 15mm of rain is expected to fall, reports the Mirror.

Winds are predicted to be southerly and strongest across the northeast coast of Scotland. Gusts of around 50mph are expected along the coastlines of Aberdeen, Fraserburgh and John O'Groats among other areas.

Winds will also be fierce along the Irish Sea coast, from Merseyside to Cumbria, and some southern areas.

In its long-range forecast covering Wednesday, September 18 to Friday, September 27, the Met Office has indicated: "Daytime temperatures will likely be above average for many regions, although some cool nights are possible with mist or fog patches developing overnight. Fairly strong winds could affect the south at times."

The reported plunge in temperatures saw the mercury descend to -2.7C in Topcliffe, North Yorkshire, according to the Met Office on Friday. Sub-zero temperatures were also recorded in Llysdinam, Powys, and South Newington, Oxfordshire.

While Scottish peaks have already seen their first snowfall of the season this past week, the Met Office regards this as "isn't unusual" even for September. The cold is set to persist today and tomorrow throughout the Scottish Highlands, yet further wintry showers are not anticipated, state the weather experts.
