Britain faces wild weather after its warmest spring equinox in over 50 years. With temperatures reaching 21°C, a severe shift unleashed thunderstorms, hail, and flooding. The M18 in Yorkshire saw closures due to rising waters, and regions like London and the East Midlands were hit by intense rain. Some areas received up to 15mm in under an hour. Met Office meteorologist Jonathan Vautrey attributes this dramatic change to recent heat, linking it to climate change's effect on weather extremes. Flood alerts have been issued, urging caution amid ongoing storms.
