Thunderstorms may bring some disruption during Friday evening, and overnight into Saturday. What to expect: Flooding of homes and businesses could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services Fast flowing or deep floodwater is possible, causing a danger to life Some communities might become cut off if roads flood Power cuts might occur and other services to some homes and businesses could be lost Spray and sudden flooding could lead to difficult driving conditions and some road closures Further details: Thunderstorms are likely across parts of eastern and southeastern England from Friday evening through to the early hours of Saturday. Although many places within the warning area may not see any impacts, torrential downpours could bring 30-50mm of rain, with a chance of even greater accumulations in a few places. With much of the rain falling in a short space of time this brings the risk of surface water flooding. Large hail, strong and gusty winds, perhaps in excess of 40-50 mph for a short period of time, and frequent lightning will be additional hazards though again many places will not see this occur. 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
