New Year's Eve revellers can expect strong winds and heavy rain as they welcome in 2023.
BBC Weather forecast that Saturday will be wet and unsettled in Pembrokeshire and Ceredigion, with further outbreaks of heavy rain pushing in from the south-west throughout the day and evening.
New Year's Day will start rather cloudy with frequent showers, these falling heavy at times, but it will turn drier with some late sunny spells in the afternoon.
Meanwhile the Met Office has issued a yellow weather warning of heavy rain for the parts on Carmarthenshire on New Year's Eve.
The Met Office said there could be as much as 10mm (0.39 in) rainfall in an hour, which could result in some surface water flooding.
The warning is in place from midnight until 21:00 GMT on Saturday.
A spokesperson from The Met Office said: “Heavy rain is expected to bring some surface water flooding and travel disruption.
“Bus and train services will probably be affected with journey times taking longer. Spray and flooding on roads will probably make journey times longer.
“Flooding of a few homes and businesses is likely.”
