Two flood warnings remain in place in Carmarthenshire.
The first is for the River Cothi at Pontargothi and Pontynyswen and a second warning has now been issued for the River Towy at Abergwili.
The agency has said further rain which is forecast to arrive in Wales on Sunday will hit saturated ground and rivers could rise quickly after any further rain.
Graham Hillier, from Environment Agency Wales said:
"We're asking people to take extra care as the risk of flooding continues.
"Our officers have been working hard over the Christmas period to clear blockages from rivers and make sure our flood defences remain in good condition.
"We're advising people to keep an eye on weather forecasts, local news reports and our website, which is updated every 15 minutes, for the latest Flood Alerts or Warnings in their area."
