Wales faces four weather warnings on Sunday and Monday including an amber “possible risk to life” warning as heavy rain may lead to travel disruption and flooding.

The Met Office issued separate warnings, for parts of north, mid and south Wales, following recent flooding from Storm Bram and “devastating” flooding in Monmouth from Storm Claudia.

Natural Resources Wales (NRW) has warned people in south Wales in particular to prepare for potential significant flooding overnight.

There is currently one flood warning and 35 flood alerts in place.

“Given the recent wet weather and saturated ground, the likelihood of impacts is higher,” the Met Office said, adding there was also a possibility of flooding in Dolgellau, Gwynedd.

“Over the next 24 to 36 hours, parts of the UK, particularly the west, will see a significant amount of rain,” a Met Office spokesperson said.

They continued: “In south and west Wales we could see another 100mm (4in) of rain falling in the next 24 hours or so, and that’s falling on saturated ground.

“We’ve had a very wet November and start to December. So, travel disruption and possible flooding of businesses and homes over the next day or two could be quite significant.”

NRW said it was continuing to monitor the situation closely and its teams were working alongside the Flood Forecasting Centre, emergency responders and local authority partners to prepare for the weather, monitoring forecasts and rainfall predictions.

Sally Davies, NRW’s duty tactical manager said their real concern was how the situation could escalate rapidly in the early hours of the morning.

“We’re urging people to be vigilant and to make preparations for potential flooding now.

“If flooding is possible in your area, think about preparing a flood kit with any important documents and medication, moving your car to higher ground and moving treasured possessions upstairs or to a higher place.”
