Heavy rain and thunderstorms expected on Monday, 23 September, could result in significant surface water flooding across parts of England, authorities have warned. The Environment Agency is advising people to stay updated on weather conditions, check their flood risk, and exercise caution when planning travel.
Persistent downpours and storm activity could bring localised flooding to urban areas and low-lying regions, with the potential for some properties to be affected and transport disrupted. While the threat of river flooding remains low, the risk from surface water flooding is heightened, particularly in areas where drains and water systems may struggle to cope with sudden, heavy rainfall.
Sarah Cook, Flood Duty Manager at the Environment Agency, issued a strong warning:
“Persistent heavy rain and thunderstorms could lead to significant surface water flooding on Monday across parts of England. The impacts could include localised flooding in urban areas and fast-responding catchments, including some property flooding as well as travel disruption. The risk from river flooding remains low.”
The Environment Agency has deployed teams on the ground, ready to support local authorities in their response to surface water incidents. Cook urged the public to heed warnings, particularly when travelling through potentially affected areas:
“We urge people to plan their journeys carefully, follow the advice of local emergency services on the roads, and not to drive through flood water – it is often deeper than it looks, and just 30 centimetres of flowing water is enough to float your car.”
Motorists are reminded that floodwater can pose serious risks, and the depth and strength of fast-flowing water can be deceiving. The Environment Agency has reiterated the dangers of driving through floodwater, which can compromise safety and lead to vehicles becoming stranded.
The forecast raises concerns for communities living in flood-prone areas, with urban drainage systems likely to be overwhelmed by the intense rainfall expected. Homeowners and businesses are being encouraged to check their flood risk online and sign up for free flood alerts to stay informed. The agency also stressed the importance of taking precautions, particularly if water levels rise quickly.
Further advice includes moving vehicles to higher ground where possible, securing loose outdoor items, and preparing flood defences if necessary. Local authorities will be working closely with emergency services to mitigate risks, and flood response teams will be on standby to deal with any immediate threats.
The public is urged to check weather updates regularly and visit the government’s flood warning service website to assess any potential risks to their area. Cook added:
“People should check their flood risk, sign up for free flood warnings, and keep up to date with the latest situation. Our teams will continue to monitor the situation and support local efforts to respond to any flooding incidents.”
Monday’s weather event follows a summer of variable conditions, and while the risk of river flooding remains minimal, surface water flooding could pose a serious threat to transport networks and low-lying residential areas.
With thunderstorms expected to sweep across the country, people are being advised to remain vigilant, stay safe, and avoid unnecessary risks.
