Hour-by-hour weather maps have revealed the places in Wales which will see the heaviest downpours on Sunday. It comes as the Met Office has given an 11-hour yellow weather warning for rain, with as much at 45mm falling in some areas.
It will be in place between 8am and 7pm, and will affect those living in Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Ceredigion, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Pembrokeshire, Powys, Rhondda Cynon Taf, Swansea, Torfaen and Vale of Glamorgan.
It comes as hundreds of rugby fans are due to arrive in Cardiff as Wales face Argentina in their first match of the autumn internationals at the Principality Stadium. There will also be remembrance services taking place across the country this morning.
The rain warning also comes just days after parts of Pembrokeshire and Carmarthenshire were submerged in water on Tuesday and Wednesday.
The extreme weather forced guests to leave a popular caravan park in Tenby, left schools closed and forced some people to evacuate their homes.
On Sunday, the Met Office forecast for Wales says: “A band of rain, heavy at times, will move slowly eastwards during today. 10-20 mm of rain falling widely with as much as 35-45 mm in a few places, chiefly over higher ground and mostly falling within six hours.”
