Parts of Pembrokeshire are already underwater, with some homes flooded up to 10ft, and other parts of south and mid Wales are also at risk.
Although not officially named yet, 'Storm Deidre' has prompted Pembrokeshire council to warn home owners and businesses in Haverfordwest town centre to prepare for flooding tonight.
The BBC reported that fire crews were tackled flooded homes in Angle, Crundale in Haverfordwest, while 10 properties in Haven's Head and Lower Priory, Milford Haven, had to be evacuated.
The Met Office has issued a "danger to life" warning for many parts of the country with heavy rain falling in a short space of time.
A yellow warning has been issued for south-west England as well as Wales, Northern Ireland and parts of Scotland.
Problems will be increased due to the large amount of rain falling withing six to nine hours which will be moving easterly as the day goes on.
Between 15-25ml of rain is expected later on today with higher ground getting between 40-60ml.
There is also an amber warning for south-west Wales – mainly covering Carmarthenshire and Pembrokeshire – where 20-40ml of rain is expected.
Gale force winds are also expected where the worst affected areas – south-west England, mainly Devon and Cornwall, west Wales and western Scotland – will get gusts between 50-55mph inland but in coastal parts this will increase to between 60-70mph.
Winds could be strong enough to generate the fourth named storm of the season – Storm Deirdre – although the forecasters are yet to officially give it the title.
The yellow warning will be in place on Saturday in Wales where an inch of rain is expected to fall in just three hours.
There are no warnings in place for Sunday.
Forecaster Alex Deakin said: "Out in the Atlantic there is a deepening area of low pressure.
"That is going to be a big player in the weather through the next few days.
"The isobars start to squeeze together – that means the winds will be picking up through the day and these weather fronts will be bringing bands of rain across all areas.
"We do have a yellow weather warning in force for wind and rain on Friday.
"Heavy rain initially across western Scotland, west Wales – it does tend to fizzle out as it makes its way towards parts of the Midlands and more central parts of Scotland.
"That active weather system sweeps in later in the day turning things wet in the afternoon across northern Ireland, Wales and south west England.
"The winds picking up as well, it's actually coming up from the south so the air is not cold – the temperatures will be in double digits, maybe up into the low teens and feeling quite mild – although obviously it'll feel colder because of the strength of the wind.

"The rain continues to work its way in through the afternoon and evening.
"We have warnings in force for parts of Wales, south west England, northern Ireland and across parts of Scotland too.
"That rain continues its way towards the east coast where it'll reach later in the evening.
"But for many Friday evening's rush hour isn't going to be very pleasant. It'll be wet, blustery, a lot spray and water on the roads.
"The winds are likely to reach 40mph, maybe 50mph inland but at the coasts we could see gusts of 60mph, accompanied by high waves – that could bring some coastal flooding.
"Through the course of Friday evening that weather tracks its way into north east Scotland, but once that band has cleared into the North Sea, we're then left with some sunshine and a whole host of showers.
"With showers, they'll come and go because of the brisk wind – although the winds on Saturday won't be as lively as they will be on Friday.
"It's going to be a blustery, boisterous weekend. Temperatures will be 10 to 14 degrees, so not cold, and more sunshine and showers to come on Sunday."
The weekend is set for hail and thunder while showers will most likely batter the south and west of the country.
Sunday will stay unsettled and breezy with showers or some longer spells, particularly in the west and south.
The best of any sunshine will be in the north and east with temperatures staying mild.
