Brits have been warned to expect huge downpours over the coming days, as a massive rainstorm heads towards the UK.

A 630-mile wall of rain is set to batter Britain on September 14, which stretches all the way from the Hebrides in Scotland to the southeast of England, according to WXCharts.

The weather is undoubtedly moving away from the warm conditions we have experienced over the summer, with England expected to face rain from around 9am on Sunday.

This forecast stretches across big cities including Birmingham, as well as Manchester, Newcastle, Southampton, Plymouth and London, the Mirror reported.

The Met Office has similarly issued a yellow weather warning, with wind speeds of up to 80mph expected in around nine regions of the UK.

This is an update from yesterday, with only four areas pinpointed to receive the harsh weather conditions.

Met Office experts highlighted the weather warning is in place from Sunday, September 14 at 8pm until Monday September 15 at 6pm.

The weather forecast reads: “Strong and gusty winds are likely to cause some disruption to travel and interruptions to power.

“Strong west or southwesterly winds will arrive across coastal areas of southwest England and Wales during Sunday evening, then develop more widely inland during Monday morning.

“Gusts of 45-55 mph are expected widely inland, with gusts of 60-70 mph possible at times along exposed coasts and hills. Winds will only slowly ease from the west later in the afternoon and into Monday evening.”

The Met Office explained the reason the weather warning has been updated is due to a “higher likelihood of lower impacts and extended over a larger area of England and Wales.”

Both the West Midlands and East Midlands are impacted by the harsh weather, with the Met Office issuing advice on what to do during the wind alert.

It said: “Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

“People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items.”If you are on the coast, stay safe during stormy weather by being aware of large waves. Even from the shore large breaking waves can sweep you off your feet and out to sea.

“Take care if walking near cliffs; know your route and keep dogs on a lead. In an emergency, call 999 and ask for the Coastguard.”Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.”
