Whilst not all areas will see these during this period, there is scope for rainfall accumulations of 20-30 mm in some places by midnight, perhaps higher in isolated locations. More widespread heavy rain, torrential in places, is anticipated during the early hours of Saturday, covered by a separate warning. 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.
