The Met Office has issued a 12-hour yellow rain warning effective from midnight to noon on Wednesday, February 21.

This forecast comes in the wake of a particularly wet weekend that saw flooding in Croscombe and has already heightened concerns over rising river levels in the region.

Forecasters are predicting an intense deluge to sweep across the area in the early hours of Wednesday, bringing with it the potential for more flooding and disruption.

Particularly at risk are areas of high ground in the South West and Wales, where up to 70mm of rain could accumulate. Given the already saturated state of the ground, there is a heightened risk of further flooding throughout the Westcountry.

"Heavy rain will spread from early on Wednesday morning across Wales and southwest England," stated a Met Office spokesperson. The expected rainfall is substantial, with widespread areas anticipating 15-25mm and higher elevations facing the prospect of 50-70mm. The saturated ground conditions are likely to exacerbate the impact, leading to disruptions across the affected areas.

The rain is forecasted to move eastward by Wednesday afternoon, alleviating conditions.

The weather warning spans a large part of the South West, stretching from Bristol to Cornwall and into South Wales. Weather maps indicate the inclement weather will commence around 5pm on Tuesday, February 20, intensifying into the night. The heaviest rainfall is predicted to occur at 2am, persisting through the morning before gradually moving east around noon.

Residents and visitors in the affected areas are advised to stay updated on the latest weather forecasts and prepare for possible disruptions caused by the heavy showers.
