Expect slow-moving showers and thunderstorms to develop on Sunday afternoon and evening, with variable rainfall accumulations in the warning area. Showers may bring up to 20 mm of rain in an hour, increasing the risk of flooding following recent wet weather. Check if your location is prone to flash flooding and prepare a flood plan and emergency kit. Stay ahead of delays by monitoring road conditions and public transport schedules, adjusting travel plans as needed. Be ready for power outages by gathering essentials like torches, batteries, and a mobile phone power pack. Seek shelter indoors during thunderstorms, avoiding trees and elevated areas. Stay updated on weather warnings as they can change rapidly.
