Torrential rains and thunderstorms have led to flooding and travel disruption to parts of the UK amid the wet start to August. Rail operators warned Monday of blocked lines and cancellations, while motorists in some parts of the country negotiated roads filled with water.
The Met Office had previously issued three yellow warnings for heavy rain and thunderstorms, covering parts of Scotland, Northern Ireland, and London and southern England, due to expire at 9pm or 11pm.
The gloomy weather comes after a weekend of downpours in which the worst landslides occurred in northern England and southern Scotland.
The Met Office said the storms brought torrential rain and lightning to the north and northeast of Scotland’s Glasgow area on Monday afternoon. National Rail Scotland said “significant rains” had caused the closure of the line between Dalmuir and Hyndland via Yoker.
Torrential rains also brought torrential rains to Edinburgh and parts of the Lothians, with ScotRail warning of cancellations between Milngavie and Edinburgh via Airdrie and Bathgate due to flooding. Local residents shared images on Twitter of the flooded streets in Glasgow and Edinburgh.
Heavy rains broke out in Northern Ireland, and motorists were urged to exercise caution on the roads due to standing water and splashes.
In England, rail operator Greater Anglia said lines between Bishop’s Stortford in Hertfordshire and Stansted Mountfitchet in Essex were blocked due to flooding.
Images taken in Greenford, west London, on Monday afternoon showed cars plowing through a flooded street, with a motorist appearing to push his vehicle through knee-deep water.
In East London, the Barking and Dagenham council informed people on Twitter that the Mayesbrook Covid-19 testing center was closed due to flooding.
The West Sussex Fire and Rescue Service urged the public not to be tempted to swim in open water after a group of youths were rescued from water currents near Lindfield. He said the incident “could easily have ended in tragedy,” adding: “Recent heavy rain has raised river levels and rapidly increased the speed of the water, making it impossible to swim safely, even in rivers. that people are familiar with. “
Meteorological Office meteorologist Matthew Box said the rains were bringing down rains at a rate of 15mm to 30mm per hour, but their movement meant they were nowhere to be found during that period of time. “When you have these big, potentially stormy, heavy rains moving, when you’re under the core of the rain, it’s very intense and the rain is coming down at great speed,” he said.
According to gauges from the Met Office, Swyddffynnon in Wales saw 31.6mm of rain between 7am and 7pm on Monday, while Salsburgh in Scotland’s North Lanarkshire experienced 29.8mm during the same period.
Further south, at Sandhurst, Berkshire, 21.6mm of precipitation was recorded, while 29.4mm fell at Plumpton in East Sussex.
The Environment Agency issued 11 flood alerts in parts of London and south-east England on Monday night, advising people to be prepared for potential floods.
The Scottish Environmental Protection Agency had issued nine flood alerts.
Box said the recent changeable weather was not unusual and was because the UK was on the colder north side of the Atlantic jet stream, which had brought an area of low pressure over the country. Longer days and more intense sunlight at this time of year create more convection, triggering thunderstorms.
Box said “fairly heavy rains” could hit eastern England and central and eastern Scotland on Tuesday, with less rain and “decent sunny spells” expected in other areas.
Summing up the forecast for next week, Box said the weather will remain “changeable” with “decent weather in the mix”, while the more “challenging” conditions will be towards the northwestern parts of the UK.
