A timespan of heavy rainfall is anticipated to pose life-threatening risks from swiftly flowing or deep floodwaters in several regions of the United Kingdom, according to the meteorologists.
The Met Office has released an amber warning for rain in the southern and central areas of Wales, spanning from Newport to Carmarthen and extending northwards towards Brecon, valid from 3 PM on Sunday until 6 AM on Monday.
This extended period of rain, prompted by a substantial low-pressure zone moving in from the Atlantic, is "expected to lead to some instances of flooding and disruption in the later part of today and overnight into Monday," the warning states.
It is anticipated that rainfall quantities reaching up to 100mm (4 inches) in certain locations will be enough to create "swiftly flowing or deep floodwaters … leading to life-threatening situations" and causing potential delays or cancellations in train and bus services.
The Met Office stated that it is likely that some communities could be isolated by flooded roads and that "homes and businesses may be at risk of flooding, resulting in damage to property."
The Environment Agency advised drivers against attempting to navigate through floodwaters and encouraged individuals to sign up for free flood alerts from the agency.
Sarah Cook, the flood duty manager, stated: "Persistent and heavy rain increases the likelihood of significant inland flooding parts of south and central Wales. Localized flooding is also possible in the south-west of England and in Cumbria over today and tomorrow morning.
"Potential impacts could include flooding of rivers and urban surface water from drains and channels. Plan your journeys carefully and do not drive through floodwaters. Water depths are often greater than they appear, and as little as 30cm of flowing water can float your vehicle."
The Met Office has also issued a series of less severe yellow warnings for wind and rain affecting various parts of the UK, including Wales, Northern Ireland, Scotland, northern England, south-west England, and the West Midlands.
