The UK is currently enjoying a heatwave, with temperatures soaring to 33°C during the bank holiday weekend. However, this pleasant weather is set to change dramatically with a 400-mile rain bomb forecasted to hit England starting June 1. Weather maps from WXCHARTS, based on MetDesk data, indicate that heavy rain, potentially reaching 5mm per hour, will affect areas from Cornwall to Newcastle, with coastal towns like Plymouth, Southampton, and Hastings expected to bear the brunt of the storm. The rain is predicted to begin around midnight on June 1 and continue until approximately 6pm on June 2, accompanied by strong winds across much of England and Wales. Although the storm will bring unsettled weather, temperatures are expected to remain above normal, with highs around 26°C during the weekend, maintaining a warm atmosphere even as conditions change. May typically sees limited rainfall, averaging between 50mm and 58mm, making the anticipated deluge a significant shift from the norm.
