Yellow Thunderstorm Warning Issued for Southern England – June 7, 2025

The Met Office has issued a yellow thunderstorm warning for Saturday, June 7, 2025, in effect from 09:00 to 18:00 BST. This alert covers southern and southeast England—including Kent, Sussex, and Surrey—as well as London, parts of the East and West Midlands, South West England, and Wales.

What to Expect

• Heavy Rainfall in Short Bursts:
  Up to 40mm of rain may fall within just a few hours. In some areas, 10–15mm could fall in under an hour, more than the total rainfall many regions saw during all of May.
• Frequent Lightning, Hail & Strong Winds:
  The storms are expected to bring intense lightning, hail, and gusty winds, which could damage homes, trees, and power lines.
• Flash Flood Risk and Travel Delays:
  With so much rain falling so quickly, flash flooding is likely, especially in low-lying or poorly drained areas. Roads and railways may be affected, with potential delays and cancellations. Drivers are warned to expect spray, standing water, and fallen debris.
• Event Disruptions:
  Several outdoor events have already been cancelled or postponed. These include the Sussex 202 Surf Ski Competition and Day One of the Kent Wind Festival, both called off for public safety.

Weekend Weather Outlook

By late Saturday afternoon, storms should begin to fade from the west. Sunday will bring drier conditions for most regions, although scattered showers may linger in the north and east.

Stay Safe: Key Advice

• Check updates from the Met Office regularly.
• Avoid unnecessary travel during the warning period.
• Secure outdoor items to prevent wind damage.
• Stay away from flooded roads and footpaths.
• Follow local authorities for emergency guidance.

In Summary

Saturday’s storm warning marks one of the most severe thunderstorm alerts of the season so far. With heavy rain, lightning, and possible flooding, residents across southern England and Wales are urged to remain cautious. As the weekend progresses, calmer weather is expected to return, but not before Saturday delivers a volatile mix of rain, wind, and dis,ruption.
