More snow could hit Caerphilly County Borough, the Met Office has warned.
It has issued a yellow “be aware” warning from Thursday afternoon until Friday night.
The Met Office said: “An area of snow is expected to develop over east and northeast England later on Thursday, and then during Friday this will extend steadily southwestwards into central and some southwestern parts of England, as well as the east of Wales.
“Whilst there is uncertainty regarding where the heaviest and most persistent snow will fall, accumulations of up to about 10cm are possible in the worst affected regions. The public should be aware that, as a result, there could be some disruption to travel.”
Last weekend snow blanketed the county borough creating problems for drivers in some areas.
