There is a likelihood of heavy showers and thunderstorms in the southern part of the area on late Sunday morning and early afternoon, gradually moving north and expanding into larger areas of rain before clearing. Some places may experience intense downpours, potentially causing up to 30 mm of rain in less than an hour and possibly 40-50 mm over a period of 2 to 3 hours, leading to surface water flooding. Additional localized hazards may include hail, frequent lightning strikes, and strong wind gusts.
To prepare for potential flash flooding, it is advised to consider 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 the arrival of gusty winds. Check road conditions before driving and adjust travel plans if necessary to avoid delays.
Prepare for power cuts by gathering essentials like torches, batteries, a mobile phone power pack, and other necessary items in advance. Seek shelter in a safe enclosed area like a car if outdoors during a thunderstorm, avoiding trees or structures that could attract lightning strikes. Stay updated on weather warnings as they may change rapidly. The Met Office recommends keeping abreast of the weather forecast in your area.
