Expect slow-moving showers and thunderstorms to develop on Sunday afternoon, with rainfall accumulations varying significantly across the warning area. Organized showers may bring 20-30 mm of rain in an hour or less, with the potential for frequent lightning and hail in the eastern region.
To prepare, assess if your location is at risk of flash flooding and plan accordingly. Secure moveable objects and temporary structures before gusty winds arrive, including bins, garden furniture, trampolines, tents, gazebos, sheds, and fences. Check road conditions for travel adjustments, and gather essential items like torches, batteries, and a mobile phone power pack in case of power cuts.
If outside during a thunderstorm, seek shelter in an enclosed space like a car, avoiding trees and other structures that may attract lightning strikes. Stay informed of changing weather warnings by regularly checking for updates.
