Heavy rain forecast on high ground until Friday
Heavy rain is expected to continue on Thursday and into the early hours of Friday bringing up to 100mm (4in) of rain on higher ground across Wales, say weather forecasters.
Natural Resources Wales (NRW) has five flood alerts in place and the Met Office has a yellow "be aware" warning.
The Met Office warning covers Conwy, Gwynedd, Ceredigion, Powys and Carmarthenshire.
The rain raises the risk of localised flooding on low ground.
The Cleddau Bridge on the A477 in Pembrokeshire was closed to high-sided vehicles in early afternoon on Thursday, but has later re-opened to all traffic
BBC Wales weather forecaster Derek Brockway said: "River levels will continue to rise and the extra rainfall may cause some flooding."
"It will be wettest on the high ground in the west and north west with mist and hill fog but drier in parts of the north and east in the rain shadow."
He said a cold front currently over Ireland will see the return of colder but brighter weather on Friday.
