There is a high chance of heavy showers and thunderstorms forming a band from southwest England to the south Midlands and parts of the Home Counties during late Sunday morning and into the afternoon. Some areas may receive 15-25 mm of rain in 1-2 hours from multiple showers moving over the same location, with a possibility of 30-40 mm in a few spots.
To prepare for potential flash flooding, assess if your area is at risk and create a flood plan along with an emergency flood kit. To avoid delays, check road conditions, bus and train schedules, and adjust your travel arrangements as needed.
Being equipped for power outages can help you handle them better. Stock up on torches, batteries, a mobile phone power pack, and other essential items. If caught outside during a thunderstorm, seek shelter in a safe enclosed space like a car, avoiding trees and structures that could attract lightning. Move to lower ground if you are in a higher area.
Remain vigilant as weather warnings may change rapidly. When a warning is issued, stay updated with the local weather forecast according to the Met Office's recommendation.
