The forecaster has also issued yellow warnings for rain in western areas of Scotland as well as Cumbria and south-west England.
In Newcastle Emlyn residents were advised to move from their homes on Saturday afternoon although many chose to remain.
Ch Insp Jacqui Lovatt, of Dyfed-Powys Police, said: “Those who decided not to leave were given appropriate safety advice – to move to the upper floor and that any valuables, essentials and food are taken upstairs.”
