There is a likelihood of heavy showers and thunderstorms developing in the southern part of the area on late Sunday morning and early afternoon, moving northward and expanding into larger areas of rain before moving out of the region. Intense downpours may occur in some areas, leading to potential surface water flooding with up to 30 mm of rainfall in under an hour and possibly 40-50 mm over 2 to 3 hours. Additional localized hazards include hail, frequent lightning strikes, and strong wind gusts.
To prepare for potential flash flooding, assess if your location is at risk and consider creating a flood plan and assembling an emergency flood kit. Secure moveable objects and temporary structures before strong winds arrive, such as bins, garden furniture, trampolines, tents, gazebos, sheds, and fences. Check road conditions, bus, and train schedules to adjust travel plans if needed to avoid delays.
It is advisable to be ready for power cuts by gathering torches, batteries, a mobile phone power pack, and other essentials to assist with coping during outages. Seek shelter in a safe enclosed area, such as a car, if caught outside during a thunderstorm. Avoid trees and structures that could attract lightning strikes and move to lower ground if on elevated terrain.
Stay vigilant for changes in weather warnings, as they can evolve rapidly. The Met Office recommends staying informed of the local weather forecast to stay prepared for any developments.
