We are urging people to prepare for the risk of further flooding across much of Wales.
A band of heavy rain is expected to hit North and West Wales late on Monday - the same areas where we issued nine Flood Warnings and 22 Flood Alerts during the weekend.
The highest rainfall totals are likely on high ground in the Cambrian Mountains, Snowdonia and the Brecon Beacons.
This in turn may cause further disruption in those areas that were affected by high rainfall over the weekend.
With the ground saturated and the rivers already swollen, this could cause rivers and streams to rise rapidly.
We again expect to issue a number of flood warnings and roads could be closed as drains struggle to cope with the volume of water.
A further band of rain on Tuesday could also cause further problems.
We are advising people to allow extra time for journeys as driving conditions may be difficult and to take care near fast-flowing and swollen rivers.
Our officers are out checking that flood defences are in good working order and that rivers are clear of debris which could restrict river flows.
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.
Martyn Evans, NRW’s Duty Tactical Manager, said: “We’re asking people to stay safe near water and to keep an eye on our website where flood alerts and warnings are updated every 15 minutes.
“People can find out if they are at risk of flooding, or sign up for our free Flood Warning service, by visiting our website or calling Floodline on 0345 988 1188.”
