Natural Resources Wales is asking people to be prepared for the possibility of localised flooding as the next band of heavy rainfall approaches.
Latest forecasts show persistent and intense rainfall is expected to reach Wales early tomorrow morning, continuing through to Tuesday, Christmas Eve.
While most parts of Wales will experience heavy rainfall at some point during the day, the worst affected areas are expected to be across the whole of south Wales, west and mid Wales.
Following prolonged periods of heavy rainfall earlier this week, ground remains saturated, meaning that further rainfall will quickly find its way into rivers and streams.
This is likely to lead to more Flood Alerts and Flood Warnings being issued across Wales in coming days.
There is also a risk that leaves and other debris, brought down by strong winds, will block drains causing flooding of road surfaces.
People travelling to see family over Christmas are advised to allow extra time as driving conditions may be difficult.
People are advised to keep an eye on local news and weather forecasts for news of any disruption in their area, and are reminded of the dangers of driving through flood water.
Officers from Natural Resources Wales are will be monitoring forecasts closely over the coming days.
Teams are out this weekend checking that flood defences are in good working order and that rivers are clear of debris which could restrict river flows.
People can find out if they are at risk of flooding, or if they can sign up for free flood warnings by calling Floodline on 0345 988 1188.
