Natural Resources Wales (NRW) has issued an alert for the whole of Bangor-on-Dee as river levels rise following days of heavy rainfall.

"Flooding of low-lying land and roads is expected. Flooding is also possible for the B5426 Straight Mile and A525 roads if conditions deteriorate further.
"Property flooding in Bangor on Dee is not expected at this time, although some localised flooding problems may result from surface water.
"We will continue to monitor the situation."
Other alerts are in place for the Lower Dee Valley and the Lower Dee catchment which includes Whitchurch.
Meanwhile, the Environment Agency has issued a flood alert for the River Dee catchment from Whitchurch to Chester, including Shocklach and Farndon.
A spokesperson said: "Flooding is possible in this area. Monitor local water levels and weather conditions. Avoid using low lying footpaths or entering areas prone to flooding. Start acting on your flood plan if you have one.
