Slow-moving heavy showers and thunderstorms will continue to affect parts of Kent and Sussex through Wednesday afternoon. Some places will miss these, but where they do occur 20-25 mm rain is likely in less than an hour with a chance of 30 to 40 mm falling in one to two hours in a few locations. This is likely to lead to some surface water flooding and disruption, whilst lightning strikes may be an additional hazard. Showers and thunderstorms will slowly die out during Wednesday evening.
