UK – Flash Floods Hit Manchester and Cornwall on Hottest September Day for 100 Years

Parts of the North and South West of England were flooded after thunderstorms and heavy rain on 13 September, while other parts of the UK experienced the hottest day of the year and the warmest September day for over 100 years.


Manchester, in the North West, saw some of the worst flooding with several streets in the centre of the city under water. The flood water inundated shops, homes and other buildings including Manchester town hall.

The floods and storms, which began at around 18:30, also caused travel chaos in and around the city. Several roads in the Greater Manchetser area were closed. Tram tracks were flooded and some lines on Manchester’s Metrolink tram network were suspended. Train services were also interrupted and Manchester Airport said that some inbound flights were delayed.

Local newspaper, Manchester Evening News, reported that “around 30mm of rain – half of a month’s worth of rain – crashed down on the region in just one hour.”

Images on social media showed flooded areas of the airport arrivals building and Piccadilly train station as well as streets and tram lines.


Storms and flooding also affected parts of Cornwall in the South West of England, causing damage to homes and disruption to train services. The worst hit areas included Falmouth, Camborne, Helston and Redruth. Some schools have been closed in the affected areas.

The first of the storms began at around 15:00, with further storms occurring throughout the evening. The Met Office said that around 40 mm of rain was recorded in Camborne.

Cornwall Fire and Rescue Service said some people were trapped in their homes by flood water.

Fire Service Group Manager Nathaniel Hooton told the BBC: “We had a large number of properties affected by the floods. That ranged from water being 1ft high in some areas, and up to waist high in others. In affected areas… some people became essentially trapped in their houses.”


The UK’s Met Office had earlier issued yellow level warnings for heavy rainfall.

The Met Office said: “A very warm and humid air mass is in place across much of the UK, with conditions marginal for thunderstorm development this afternoon as temperatures rise.

“Northern England and southeast Scotland are currently judged the most likely area to see scattered thundery downpours but even here many places will have no more than light rain.

“However, where storms do form, there is a lot of moisture and energy available, with the risk of more than 30mm of rain in around an hour, large hail and frequent lightning.”

Hottest September Day for Over 100 Years

The Met Office said that 13 September 2016 was the hottest day of the year, “with 34.4 °C recorded at Gravesend. This makes it the warmest September day since 1911.”
