Natural Resources Wales (NRW) is warning people of the risk of further significant river and surface water flooding this weekend as Storm Dennis is expected to reach Wales.
Heavy rain and strong wind are forecast across most of the country from Saturday afternoon (15 February) into Sunday and is likely to cause considerable disruption.
With river levels still very high and ground already saturated following Storm Ciara, the risk of flooding is significant as rivers are likely to rise quickly.
NRW expects to issue wide-spread flood alerts and warnings with the highest rainfall amounts likely to be over the South Wales Valleys, but high levels expected over Snowdonia, the Cambrian Mountains, and the Brecon Beacons.
NRW staff are working around the clock to prepare for Storm Dennis - monitoring forecasts and rainfall predictions, ready to send flood warnings as and when necessary.
Officers are also out in communities across Wales, alongside local authorities, checking defences and making sure any drainage grids and screens are clear, to reduce the risk to people and their homes.
Jeremy Parr, Head of Flood and Incident Risk Management for NRW, said:
“We expect the worst of the rain on Saturday afternoon and overnight into Sunday, which could see many flood alerts and warnings issued.
“There is potential for significant impacts across Wales, from river flooding and from surface water. Transport and travel will likely be disrupted too.
“We urge people to stay safe and be careful this weekend – don’t be tempted to drive or walk through flood waters, you don’t know what lies beneath.
“Keep an eye on weather forecasts and visit our website for latest information on the flood warnings. You can find practical advice on flooding on our website too.”
Flood alerts and flood warnings are updated on the Natural Resources Wales website every 15 minutes.
Information and updates are also available by calling Floodline on 0345 988 1188. People can also register for free flood warnings either by calling the Floodline number or on NRW’s website www.naturalresources.wales/flooding
