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.
A warm and very humid day across Northern Ireland will help in the development of scattered heavy showers and thunderstorms. Whilst many areas will miss these, where they develop 10-20 mm of rain could fall in less than an hour, with a chance of a few areas seeing 20-30 mm in less than an hour. This could lead to some flooding in places. Lightning, hail and gusty winds will be additional hazards.
By evening showers and thunderstorms may merge into longer spells of rain, especially across western areas.
