This afternoon heavy showers and thunderstorms will move eastwards, gradually diminishing later in the evening. In areas where storms are frequent, there may be a build-up of 20 to 30 mm of rain over 2 to 3 hours. Additional hazards in some places include frequent lightning, hail, and gusty winds.
To prepare for potential flash flooding, assess if your location is at risk and create 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 gusty winds arrive.
Check road conditions and transport timetables to avoid delays. Prepare for possible power cuts by gathering torches, batteries, a mobile phone power pack, and other essentials.
If caught outside during a storm, seek shelter in a safe enclosed area, like a car, and avoid trees or structures that may be hit by lightning. Stay informed as weather warnings may change rapidly. The Met Office advises staying up to date with the weather forecast in your area.
