Dyfed Powys Police say they've dealt with around 40 to 50 flooding related incidents today.
Approximately 25 properties have been damaged by floods, in areas such as Llanelli, Bury Port, Pembrey, Furnance, as well as parts of Swansea, Skewen and Neath.
"It's not stopped" said Vale of Glamorgan resident David Apjohn-Williams.
"The rain's been coming down through the fields, and down through the stream as well".
Five flood warnings are currently in place across Wales.
Crews are attending flooding incidents in the Neath Port Talbot, Swansea, and Llanelli area's. #flooding

Parts of south Wales have seen around another 1.5 inches (32mm) overnight and that's on top of the rain that fell late last week. The ground is already saturated leading to many examples of localised flooding. There are also a number flood warnings on rivers around Wales.
The Met Office has a yellow warning in force across the whole of Wales, but counties between Carmarthenshire and Monmouthshire have an amber warning in force. The coastal district around north Ceredigion and south Gwynedd also has an amber warning for heavy rain.
This afternoon after a lull in the rain, the wet weather will return with the possibility of another 40-60mm (around 2 inches) of rain possible. A very mild afternoon with highs of 12-13C but it's windy too.
After a wet evening across the country, the rain will push northeast leaving a drier night.
There will be some showers around though and it will be very windy and mild. Milder overnight than we'd expect for daytime highs at this time of the year.
Tomorrow will be brighter in the north but a risk of seeing yet more rain pushing to southern parts of Wales later in the day.
