Scattered heavy showers, some with thunder, are expected to develop later this morning and into the afternoon, before easing this evening. In the most active storms, hail, strong gusty winds, and lightning may be impactful. There is also a chance that a few spots could see frequent, heavy bursts of rain, leading to surface water flooding. What Should I Do? Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car). Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground. Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.

Thunderstorms associated with scattered heavy showers may cause some impacts during Wednesday
