Yellow weather warnings in place across all four countries also mean short term losses of power and other services are expected this afternoon as well as delays to transport. Flood warnings have been issued for Wales and flood alerts for elsewhere in the UK. Meteorologist Alex Deakin said: “We do have warnings in force: parts of Wales, south-west England Northern Ireland.
“And across parts of Scotland to, chiefly over the hills, as that rain continues to head its way.
“Not reaching parts of the east coast until well into the evening but for many Friday evening’s rush hour isn’t going to be very pleasant.
“It will be wet and it will be blustery.
“A lot of spray, a lot of surface water on the roads and those winds likely to reach 40mph, maybe 50mph inland, and around the coast we could see winds up to 60mph, accompanied by high waves that could bring some coastal flooding.”
The Met Office said immediate action was needed in Haverfordwest, Middle Hill, Solva and Quayside in Wales.
A further 11 flood alerts have been issues.
The weather front starts as a deepening area of low pressure to the west of the British Isles before moving east and forming a north-south band of rain.
The four main patches of adverse weather will hit Wales and south-west England, northern Ireland and two patches in Scotland.
Spray and flooding on roads are expected to make journey times longer, with some delays to rail, air and ferry transport too.
There will also likely be delays for high-sized vehicles on exposed routes and bridges.
However, Mr Deakin said temperatures will not be too bad, as the wind is coming from the south so it won’t be too chilly.
He added: “Although of course, it will feel colder because of the strength of the wind and the rain, which continues to work its way in through the afternoon and evening.”
