The Met Office has issued an updated yellow weather warning for heavy rain across a significant portion of Wales, now extending its coverage to include five additional areas. This expansion signals a heightened risk of disruption for residents and infrastructure, with the warning active from 3am on Saturday until 6pm on Sunday.
Initially covering several regions, the updated warning now encompasses a broader swathe of the country, reflecting a revised forecast for persistent and heavy downpours. The newly added areas are understood to be particularly vulnerable to the impacts of such rainfall, including potential surface water flooding, disruption to transport links, and difficult driving conditions.
Forecasters anticipate that some areas within the warning zone could see between 30mm to 50mm of rain, with isolated spots potentially receiving up to 70mm, particularly over higher ground. Wind speeds are also expected to pick up, with gusts possibly reaching 40-50 mph in exposed coastal areas, exacerbating the challenging conditions. This combination of heavy rain and strong winds increases the likelihood of localised flooding and potential damage to property and infrastructure.
Across England, Scotland, and Northern Ireland, the immediate forecast generally remains less severe, though localised showers are expected in parts of the South West of England and western Scotland. Temperatures across the UK are predicted to be mild for the time of year, ranging from 8-12 degrees Celsius in the south and 5-9 degrees Celsius further north. However, the focus of the most significant weather impact remains firmly on Wales, where communities are advised to remain vigilant.
Authorities are urging residents in affected Welsh areas to prepare for potential disruption. This includes checking local flood warnings, clearing drains where safe to do so, and making contingency plans for travel. Drivers are advised to exercise extreme caution on roads, be aware of standing water, and avoid unnecessary journeys during the peak of the rainfall.
