Expect slow-moving showers and thunderstorms to develop on Monday, with varying levels of rainfall across the warning area. Some places may see 10-20 mm of rain in an hour, with a possibility of up to 30-40 mm over a few hours. Lightning may also be a concern.
To prepare, assess whether your location is at risk of flash flooding and create a flood plan and emergency kit if necessary. Secure moveable objects and temporary structures before gusty winds arrive, such as bins, garden furniture, trampolines, tents, gazebos, sheds, and fences.
Stay informed of road conditions if driving, or bus and train timetables if using public transport. Be ready for power cuts by gathering torches, batteries, a mobile phone power pack, and other essentials. If caught outside during a thunderstorm, seek shelter in a safe enclosed area like a car, avoiding trees and other structures at risk of lightning strikes.
Weather warnings may change suddenly, so keep updated on forecasts from the Met Office.
