Expect heavy showers and thunderstorms in the southern part of this region on late Sunday morning and early afternoon, moving northward and expanding into larger rain bands before exiting the area. Some areas may experience intense downpours, with up to 30 mm of rainfall within an hour and possibly 40-50 mm over 2 to 3 hours, which could lead to surface water flooding. Additionally, hail, frequent lightning strikes, and strong wind gusts are potential localized hazards.
To prepare, assess if your location is prone to flash flooding and consider creating a flood plan and emergency flood kit. Secure moveable objects and temporary structures, like bins, garden furniture, trampolines, tents, gazebos, sheds, and fences before the arrival of gusty winds. Check road conditions and public transport schedules to avoid delays.
For power outages, gather torches, batteries, a mobile phone power pack, and other essentials to better cope. If caught outside during a thunderstorm, seek shelter in a safe enclosed area, like a car, and avoid standing near or under trees or structures that could attract lightning strikes. Be ready for rapid changes in weather warnings by staying informed with the latest forecasts from the Met Office.
