Further detail

Heavy showers and thunderstorms are likely to break out across parts of England and Wales on Thursday afternoon. The exact location of showers is still uncertain and some places will stay dry all day. However, where the showers do occur they could be torrential, with the additional hazards of lightning, hail and gusty winds. The heaviest showers could result in 20-30 mm within an hour, with 24 hour accumulations possibly reaching as much as 70-90 mm where multiple showers affect the same location. 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.
