A FLOOD warning has been issued for all areas near the River Clwyd amid heavy rain on Wednesday morning.

Flood water is gathering on roads and near homes across the county, with the north most affected, as parts of North Wales have seen nearly double their monthly average rainfall in the last five days.

Natural Resources Wales issued the warning to advise riverside homeowners from Rhuddlan to Clocaenog to "be prepared" for flooding. It said the River Alwyn has already burst its banks in Rossett, north of Wrexham.

The environmental agency added that isolated properties and extensive areas of agricultural land are most at risk.

In Llangollen firefighters have been pumping water out of a caravan park for more than 12 hours.

Loggerheads Country Park is also closed due to flooding, with water levels still rising.

Traffic problems caused by surface water flooding have hit Dyserth, with Y Pandy and Waterfall Road closed, while the A5151 between the village and Rhuddlan has standing water.

In Rhyl, Seabank Drive is closed, as well as Westbourne Avenue where residents have been issued sandbags.

To the south of Denbighshire, in Ruthin and Denbigh, the A525, Llanrydd Street, Denbigh Road and Lower Denbigh Road have surface water in several places.

The B5430 between Valley Lodge and Pistyll Gwyn Quarry, Llanarmon yn Iâl has been closed.

The A5 is shut in Corwen in both directions. Diversions are in place to join the A494.

Meanwhile a tree has fallen on the A543 between Bodfari and Afonwen.

TV weather presenter Ruth Wignall tweeted: “Parts of North Wales had almost twice the monthly average rainfall in the last five days! Up to 155mm with more significant rain coming tonight.”

There were problems with surface water on the A539 at Llangollen overnight. Denbighshire County Council officers were in attendance and cleared the flood water.

A spokesperson for the council said: “The rain is expected to ease this afternoon but more is expected overnight.

“Residents are advised to continue to monitor weather forecasts and social media for any updates."
