What should I do?
Reason for update
Warning area adjusted to remove parts of south and southwest England and West Wales, whilst including more of northern England. Period of validity has been delayed by 1 hour, whilst the likelihood of impacts has been increased.
Heavy showers and thunderstorms are likely to break out in the south and west of this area early Sunday afternoon, moving steadily north whilst growing into larger areas of heavy rain before clearing through the late evening. Some intense downpours are possible in a few places, giving up to 30 mm in less than hour and perhaps 50 mm over 2 to 3 hours leading to surface water flooding. Large hail, frequent lightning strikes and possibly strong wind gusts will be additional localised hazards. 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.
