Showers and thunderstorms are forecasted to develop slowly on Sunday afternoon and evening, with varying rainfall amounts expected across the warning area. In areas where showers become organized, there is a possibility of 20 mm of rain falling in an hour, increasing the risk of flooding following recent wet weather conditions.
If you are in an area prone to flash flooding, it is important to consider creating a flood plan and an emergency flood kit. To avoid delays, check road conditions before driving, or bus and train schedules if using public transportation, and make any necessary adjustments to your travel plans.
Prepare for potential power outages by gathering essential items such as torches, batteries, a mobile phone power pack, and other necessities ahead of time. If you are outdoors during a thunderstorm, seek shelter in a safe enclosed area like a car, and avoid seeking shelter near trees or structures that may attract lightning strikes. If you are on higher ground, move to a lower elevation.
Be ready for rapid changes in weather warnings by staying updated with local weather forecasts when a warning is issued by the Met Office.
