Residents in Henllys, Torfaen, and surrounding areas are urged to prepare for significant rainfall as the Met Office has issued a yellow weather warning for the region. The warning comes into effect from 9am on Thursday and is expected to remain in place until 6am on Friday, indicating a prolonged period of wet weather.
Forecasters predict that much of the warned area could see between 20mm and 30mm of rain, with isolated pockets, particularly over higher ground, potentially experiencing up to 50mm. This volume of precipitation in a relatively short timeframe raises concerns about surface water flooding, which could impact homes and businesses.
The Met Office has highlighted several potential impacts, including difficult driving conditions due to spray and standing water on roads, leading to longer journey times. There is also a possibility of disruption to bus and train services, and a slight chance of power cuts to some homes and businesses.
Across the wider UK, while the focus is on Wales, other regions are also bracing for unsettled weather. Northern Ireland is expected to see scattered showers, though not as persistent or heavy as those forecast for parts of Wales. England's South West could also experience some heavier downpours, while Scotland is likely to see a mix of sunshine and showers, with temperatures generally milder than average for the time of year.
Temperatures in Henllys during the warning period are expected to range between 9 and 12 degrees Celsius. Wind speeds are anticipated to be moderate, around 10-15 mph, but could gust higher in exposed areas, exacerbating driving conditions. The Environment Agency advises residents to check their flood warnings and prepare for potential impacts, particularly if living in low-lying areas or near watercourses.
Local authorities in Torfaen are likely to be monitoring the situation closely, urging residents to secure any loose outdoor items and to avoid driving through floodwaters. Further updates from the Met Office and local councils are expected as the weather system approaches.
