Headline

What to expect?

  • There is a small chance that some communities are temporarily cut off by flooded roads

Further details

Scattered slow-moving heavy showers and thunderstorms are likely to develop across parts of Wales and southwest England during Saturday afternoon. Whilst many places will see little or no rainfall, some locations could see 20-30 mm in an hour or two. There is a small chance that repeated shower development could result in a few places seeing 40-50 mm. Showers and thunderstorms will gradually fade during Saturday evening. What should I do? Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit. Prepare to protect your property and people from injury. Before gusty winds arrive, check to ensure moveable objects or temporary structures are well secured. Items include; bins, garden furniture, trampolines, tents, gazebos, sheds, and fences. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car). Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground. Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
