Heavy rainfall is expected to cause flooding in parts of the UK today, as nearly a month’s worth of rain is forecast to fall within a few hours. Two yellow weather warnings have been issued, with downpours moving eastwards throughout the day. Areas like Wales could see up to 70mm of rain, raising concerns about flooding, travel disruptions, and potential power outages.
Communities in southwest Wales, such as Swansea, usually experience 75mm to 80mm of rainfall in an average September. These areas, along with places like Merthyr Tydfil and Llandeilo near Bannau Brycheiniog National Park, are under one of the weather warnings today. The anticipated downpours could match the typical rainfall for September, urging residents to prepare.
In north Wales, heavy rain is expected, with places like Gwynedd and Eryri National Park likely to be affected. Harlech in Gwynedd usually sees 80mm of rain in September, but today’s forecasted 60mm could lead to flooding and potential isolation of communities.
The Met Office warns of travel delays and flooding in certain areas due to persistent heavy rain moving across south and southwest Wales. The Midlands, particularly Staffordshire and Birmingham, will also face heavy rainfall before it turns showery in the East of England later in the day.
While the Midlands has not received a weather warning yet, concerns remain high as Birmingham typically sees around 68mm of rain in September. Flood alerts are already in place for rivers in Cumbria and Devon, with fears of rising water levels and potential risks to campsites and nearby areas.
Natural Resources Wales has issued flood alerts for various regions, emphasizing the need for caution and preparedness. The upper Towy catchment in Carmarthenshire and rivers in Llanelli, Llangennech, Pwll, and Burry Port are among the areas of concern.
