A few thundery showers may be present across southern and southeast England early on Friday, but from the middle of the day they are expected to develop more widely within the warning area. Whilst some places will remain dry, where thundery showers do occur, they will bring frequent lightning, gusty winds, potentially some large hail, as well as brief spells of heavy rain. 15-25 mm of rain fall may fall within an hour, with a very small chance of 30-40 mm falling in 3 hours; the latter most likely across southwest England. Showers will tend to ease and fade during Friday evening.
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. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
