RED warning issued as major flooding hits South Wales

(Update: Red warning now lifted however conditions remain dangerous in places)

A red weather warning has been issued by the UK Met Office for the South Wales area – in particular the valleys area. Exceptionally persistent and heavy rain during the last 24 hours, with totals over 150mm (6″) on high ground, has lead to the bursting of many rivers banks and flooding of properties as associated river catchments continue to drain their loads. As this occurs throughout today (Sunday 16th February), river levels are expected to continue to remain exceptionally high through much of the dray, resulting in a continuation of life-threatening conditions.

Areas included in Met Office Red warning:

Much of the South Wales valleys and populated areas nearby for examples the rivers TAFF, USK and NEATH. Populated areas include Cwnbran, Pontypridd, Merthyr Tydfill, Mountain Ash, and Blackwood. 

The river Taff has completely burst it’s banks by Treforst, South Wales. These images were sent into us by Jessica Walton at roughly 6.30am of the river’s flood waters affecting properties. Look at the speed of the waters, another hazard associated with this exceptional event – likely of carrying dangerous items posing a risk to life.

  • Presence of danger to life from fast flowing or deep floodwater

  • Extensive flooding to homes and businesses likely

  • Collapsed or damaged buildings or bridges
