Yellow Weather Warnings Issued for Thunderstorms and Flooding Across England and Wales

The Met Office has issued yellow weather warnings for thunderstorms across England and Wales for Wednesday and Thursday. These warnings cover the West and East Midlands, the North West, South East, South West, east of England, and all of Wales. Forecasters warn of a risk of flash flooding, travel disruption, and large hail. On Wednesday, intense downpours of 20 to 30mm of rain could fall in less than an hour, with some areas potentially seeing 40 to 50mm within three hours. Thursday's forecast includes slow moving heavy rain with potential accumulations of up to 50mm in 12 hours, and a small chance of exceeding 75mm over east facing high ground.

The Environment Agency has issued five flood alerts for specific areas, including the River Trent tributaries and urban watercourses in Loughborough and Nottinghamshire. Met Office chief forecaster Steve Willington attributed the unsettled weather to warm and humid air moving north. The storms follow a period of record breaking dry conditions, with almost three quarters of England and all of Wales designated as being under drought. Experts noted that heavy rain following such a dry summer could increase the risk of flash flooding.

Looking ahead to the Bank Holiday weekend, forecasts suggest continued wet weather. Heavy downpours are expected on Saturday, with high rain coverage predicted for Cardiff, Manchester, and London. While Sunday is expected to remain wet across England, Wales, and Scotland, some sunny intervals and highs of 22C are forecast for London and the south on Monday.
