Introduction to the Weather Warning
The weather in Wales has been better than expected on Saturday, but this respite will be short-lived as a weather warning for heavy rain has been issued for Monday and Tuesday. The Met Office has upgraded the warning for south Wales from yellow to amber, indicating that flooding across the region is "probable" and could cause a "danger to life". This warning will be in place from midnight to 11pm on Monday and will cover the majority of south Wales, including counties such as Blaenau Gwent, Bridgend, and Caerphilly.
Details of the Weather Warning
The Met Office has stated that an area of heavy rain is expected to move over central and south Wales between late Sunday and late Monday. Whilst rainfall amounts will vary, some heavy and persistent rainfall is likely to fall, especially over high ground. The areas affected by the weather warning on Monday include Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Neath Port Talbot, Newport, Pembrokeshire, Powys, Rhondda Cynon Taf, Swansea, Torfaen, and Vale of Glamorgan. The Met Office has warned that 20-40 mm of rain is likely to fall quite widely across the wider region, but 60-80 mm is likely to accumulate over some windward-facing high ground in south Wales, and perhaps nearer 100-120 mm in a few places.
Potential Impacts of the Weather Warning
The Met Office has warned that homes and businesses could be flooded, causing damage to some buildings. Meanwhile, delays or cancellations to train and bus services are possible, and spray and flooding could lead to difficult driving conditions and some road closures. Power cuts and loss of other services to some homes and businesses are also possible, and some communities may be cut off by flooded roads. The Met Office has said that "fast flowing or deep floodwater is possible, which could cause a danger to life". This warning is not limited to Monday, as another yellow warning for rain will be in place between midnight and 3am on Tuesday, covering north Carmarthenshire and large parts of mid and north Wales.
Additional Weather Warnings
In addition to the amber warning for south Wales, there are two other warnings that affect Wales. A yellow warning for rain will be in place for the vast majority of Wales between midnight and 3am on Monday, and another yellow warning for rain will be in place between midnight and 3am on Tuesday, covering north Carmarthenshire and large parts of mid and north Wales. The Met Office has warned that significant rainfall is expected across these regions, and residents should be prepared for potential disruptions to daily life.
