The Met Office said to expect some spray and flooding on roads, some interruption of power supplies, bus and train services to be affected and the flooding of homes and businesses to be likely.
A Met Office spokesman said: "An area of heavy rain reaching southwest England late Wednesday afternoon spreads eastwards across southern England, reaching the far southeast of England by mid-evening.
"Rain will last for around six hours in any location, finally clearing southeast England during the early hours of Thursday.
"Rain may be accompanied by coastal gales and, in a few places, thunder. 15 to 25 mm of rain is widely expected with 30 to 50 mm possible in a few places."
