Expect slow-moving showers and thunderstorms to develop on Sunday afternoon, with varying rainfall accumulations across the warning area. Organised showers may result in 20-30 mm of rain falling in an hour, along with frequent lightning and hail, particularly in the east.
To prepare, assess the risk of flash flooding in your area and create a flood plan and emergency kit. Secure moveable objects and structures before gusty winds arrive, including bins, furniture, trampolines, tents, sheds, and fences.
Check road conditions and transport schedules, and prepare for potential power cuts by gathering essentials like torches, batteries, and a mobile phone power pack.
If outside during a thunderstorm, seek shelter in a safe enclosed area like a car, avoiding trees and other structures that may attract lightning strikes. Stay informed of weather warnings that may change quickly by keeping up-to-date with the forecast from the Met Office.
