The UK's national weather service, Met Office, on Monday issued warnings of delays on the roads due to flooding caused by heavy downpours.
One yellow and one amber rain warning have been issued across larger parts of the country, reported the Mirror.
The yellow warning, covering many parts of England and Wales, is expected to be in force from midnight on Monday until midnight on Tuesday.
According to forecasters, the Midlands, northeast England and east Wales are likely to get the most rainfall, with around 30mm to 50mm set to fall in six hours or less.
However, some areas could see 80mm to 100mm over the course of 12 to 24 hours.
Meanwhile, the amber warning is more severe and is in force from 5 am till 9 pm on Monday covering many parts of Southern and central England. Heavy rain accompanied by flooding and lightning might cause travel disruption and may be an additional hazard in some areas.
The more severe amber warning, in force from 5 am until 9 pm on Monday, says that heavy rain is expected to produce flooding and travel disruption. The amber warning, covering parts of central and southern England, says lightning may be an additional hazard in some areas.
Scotland, Ireland, and north-west England can expect a relatively brighter day, with a mix of showers and sunshine in south-east England. On Tuesday, the northern areas and Scotland are expected to see a "bit of a swap," with longer spells of rain, while much of the south, Wales, and the Midlands are expected to have a mostly dry day.
The Met Office on Sunday, urged people going out Monday morning to take care. The weather service wrote on X, "Take care as you head out on Monday morning - heavy rain could bring flooding and disruption for parts of England and Wales. Cloudy for most of Northern Ireland and Scotland, with patchy rain arriving into the far north."
The flood duty manager at the Environment Agency, Sarah Cook, said there is a risk of surface water flooding on Monday, "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."
She further urged people to plan their journeys carefully, following the advice of local emergency services and not to drive through flood water, “It is often deeper than it looks and just 30cm of flowing water is enough to float your car."
Criswick said that more rain is expected at the beginning of next week in areas that have received rain over the last couple of days.
"We have just recently issued an amber warning as well for similar areas across parts of the Midlands and also just moving up into the north-east of England as well. So where we've seen have accumulated rain over the last day or so we're expecting further rain as well. It's likely we'll see more impacts from flooding and road closures and things like that."
Over the weekend, several streets across the UK were submerged as flooding damaged buildings and cars. Photos on social media showed parts of Dunstable in Bedfordshire and Hitchin in Hertfordshire under water. Heavy rain left shops and vehicles partially submerged, prompting the Environment Agency to issue flood warnings for areas near the River Lee in Luton and the River Ivel at Langford.
According to news agency Stoke-on-Trent Live, cars were left stranded in North Staffordshire, cars were left stranded in around two feet of sludge after a "mudslide". Saturday's heavy downpour caused chaos on Cheadle Road in Draycott in the Moors where residents say there was a "sea of mud".
Heavy rain is expected across central and southern areas, merging into broader bands by dawn. The north will remain cloudy with light rain and drizzle, staying cool, while the south will be warm and humid.
On Monday many regions across central and northeastern England have been flooded as a result of consistent heavy and persistent rain. Thunderstorms are expected in the southeast, while the north will remain mostly cloudy with occasional rain in northern Scotland.
From Tuesday to Thursday, the weather is expected to be fairly settled with sunny spells and probably some showers. It will turn cooler, widely wet and windy Wednesday onwards.
