Expect heavy showers and thunderstorms to develop in the southern part of the area on late Sunday morning and early Sunday afternoon, gradually moving northward and expanding into larger areas of rain before exiting. There is a potential for intense downpours in some locations, with up to 30 mm of rain in under an hour and possibly 40-50 mm over 2 to 3 hours, leading to the risk of surface water flooding. Localized hazards may include hail, frequent lightning strikes, and strong wind gusts.
To prepare for the possibility of flash flooding, assess the risk in your area and consider creating a flood plan along with an emergency flood kit. Secure moveable objects and temporary structures, such as bins, garden furniture, trampolines, tents, gazebos, sheds, and fences before the arrival of gusty winds. Stay informed about road conditions, public transport schedules, and consider adjusting travel plans if necessary.
Ensure you are ready for power outages by gathering essential items like torches, batteries, a mobile phone power pack, and other necessities. If caught outside during a thunderstorm, seek shelter in a safe enclosed space like a car, and avoid standing near trees or other structures that may attract lightning strikes. Stay alert to changes in weather warnings, as the forecast can shift quickly. Stay updated with the latest weather information in your area according to the Met Office's recommendations.
