Flood alerts are being made as heavy rain and thunderstorms are forecast for the whole of Wales.
The Met Office is forecasting heavy showers, which could be intense in places, to hit north Wales this evening and affect the whole of Wales Tuesday and into Wednesday.
Natural Resources Wales says due to the recent warm weather the ground is particularly hard meaning water will run off more quickly into drainage systems. There is a risk that this cause roads to flood and drains, ditches and small streams to overflow.
People travelling home from work, on their holidays or events like the Royal Welsh Show, are advised to take extra care, as driving conditions could be difficult.
Those camping or caravanning should also keep an eye on the weather conditions and listen to advice from site owners.
