The fire service were called out after flash flooding in Cardigan yesterday (Monday).
And with more heavy rainfall and thunderstorms expected over the next few days, they are urging drivers to take extra care on the roads.
On Monday, Mid and West Wales Fire and Rescue Service attended flooding incidents in Cardigan, as well as Ystradgynlais, Cwmtwrch, Abercrave and Narberth.
Area manager Craig Flannery, MAWWFRS, said: “Due to the heavy rainfall and thunderstorms that are expected over the next few days, we urge all drivers to take extra care on the roads.
"Please do not drive through floodwater. By doing so, you are putting yourself and others at unnecessary risk. It only takes one foot, or 30cm, of moving water to float your car and as little as an eggcup-full of water, going into your engine, is enough to wreck it.
"Flood water can be deceptively powerful – it can literally rip up the road surface and dislodge manhole covers and kerbstones – and its depth and flow rate can quickly change with the weather.
"So please, if you are driving and come across floodwater on the road, just turn around rather than put yourself and your vehicle at risk."
