Weather: Flooding fears as more rain expected across Wales
Some communities could be cut off by flooded roads as more rain is expected across Wales, the Met Office has said.
A weather warning is in place until Tuesday evening, with difficult driving conditions in some areas.
The Met Office also said homes and businesses could be flooded, with a number of flood warnings already in place after days of rain.
Flooding means trains have not been able to run on the line between Machynlleth and Newtown in Powys.
Replacement buses are in place until the end of Tuesday.
Surface water has affected some roads and highways officials said patchy fog hit travel on the A55 across north Wales until late morning.
There are several flood warnings across Wales, according to Natural Resources Wales.
On Monday, an attempt to rescue about 20 cows which had become stranded by floodwater in a field in Abergwili, Carmarthenshire, had to be abandoned.
The Met Office weather warning, which covers most of Wales, is in place until 20:00 BST. Up to 50mm (2in) of rain is possible in some places in only a couple of hours, forecasters said.
