Met Office points AMBER warning for rain with flooding anticipated to trigger havoc: UK climate map reveals the place will probably be worst hit in a single day

After a few days of blue skies, Brits are bracing for torrential rain, flooding, and 75mph winds overnight as weather warnings have been issued across the UK.

A new map reveals the worst-hit areas with parts of the country covered by yellow or amber warnings.

Flooding and power cuts are expected, while some areas may experience travel disruptions across roads and rail.

The Met Office has issued amber weather warnings for rain and wind in south Wales, and yellow warnings in the rest of Wales and south west England.

The first warnings came into place today at midday with the last due to be lifted at 8am on Monday.

Parts of central and northern England including London are not covered by the warnings and are expected to miss the worst of the weather.

Residents from Wales and south west England, including Cornwall and Devon have been told to expect travel disruptions such as bus and train services.

Warnings also include potential flooding to roads and homes in the area as well as possible power cuts.

In areas including Cardiff, Swansea and Newport, up to 50-77 mm of water is expected to fall over high ground.

While places with exposed hills could have as much as 100mm of rain. 

The entire UK should expect strong winds with central, northern and western areas experiencing gusts up to 60mph.

Spots along Irish Sea Coastlines, Scottish Islands should brace for even stronger 75mph winds.

Andy Page, Met Office, Chief Meterologist said: ‘We are now entering of period weather being influenced by low pressure systems from the Atlantic. 

‘Strong winds and heavy rain during Sunday will bring the potential for travel disruption, dangerous conditions near coasts and the possibility of power cuts for some.

‘As well as a number of yellow warnings for wind and rain we have issued an amber rain warning covering part of South Wales.

‘As this rain is falling in an area where the ground is already wet there is the likelihood it could cause some impacts.

‘It is also windy with many central, northern and western parts of the UK seeing gusts of up to 50-60 mph at times, and as much as 65-75mph in exposed spots along Irish Sea coastlines, Scottish Islands, and other areas of high ground further inland.’

Parts of the UK without warnings should also expect wet weather.

And these bleak conditions are expected to continue into next week with longer spells of rain and temperatures dropping in the UK.

The Environment Agency warned people not to drive through water.

Sarah Cook, flood duty manager at the Environment Agency, said: ‘Heavy and persistent rain brings a risk of significant inland flooding in parts of south and mid Wales.

‘Impacts could include river flooding and surface water flooding from urban watercourses, drains and channels. 

‘Please plan journeys carefully and do not drive through flood water – it is often deeper than it looks and just 30cm of flowing water is enough to float your car.’

On Monday the rain is expected to clear in the southeast and sunshine will spread across the UK.  

The south will experience mild temperatures but the north will have average temperatures.

Later on in the week, there will be glimmers of sun and showers of rain on Tuesday followed by heavy rain on Wednesday. 

Luckily, Thursday will be drier and brighter away from the far north and far southwest.
