Yellow weather warning for rain across 16 areas of Wales

A yellow weather warning for rain has been issued for Wales on Monday and Tuesday, with 16 areas of the country covered. Low pressure is dominating this weekend, bringing wet and windy conditions for many.

As we move into the new working week, there is potential for more disruptive weather. The 24-hour warning is affecting Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Ceredigion, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Pembrokeshire, Powys, Rhondda Cynon Taf, Swansea, Torfaen and Vale of Glamorgan.

There are already multiple flood warnings in place across Wales and reports of flooded roads and train lines.

The warning starts on Monday at 6pm until Tuesday at 6pm.

The Met Office states: “Outbreaks of rain will become persistent and heavy on Monday night into Tuesday morning, and whilst the rain may be more intermittent during Tuesday daytime some occasional heavy bursts will still be possible.

“There will naturally be some variation in rainfall totals across the area, but accumulations of 20-40 mm are likely in quite a few places, with 60-80 mm over Dartmoor and high ground in south Wales.

“There is a small chance of 80-100 mm falling over the most exposed, prone hills.

“Given the saturated nature of the ground, this is likely to lead to some flooding in places and transport disruption.

“Rain will also be accompanied by strengthening southerly winds, which may exacerbate impacts.”

The meteorological service warns that spray and flooding could lead to difficult driving conditions and some road closures, and that, where flooding occurs, there is a slight chance of delays or cancellations to train and bus services.

It adds that there is a small chance that some communities will become cut off by flooded roads, and a small chance that homes and businesses could be flooded, causing damage to some buildings.

There is a chance of fast flowing or deep floodwater causing danger to life, and a slight chance of power cuts and loss of other services to some homes and businesses.

Offering advice on what you should do to prepare yourself, the Met Office adds: “Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

“Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

“People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items.

“Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.”
